There’s a lot of confusion around the term red dot sight. It doesn’t refer to one specific optic but rather a whole category of sighting systems.

In simple terms, “red dot” covers multiple optic types — including reflex, holographic, and prism designs — all using an illuminated aiming point to improve speed and precision.

Which red dot do you need?

When someone says they’re looking for a red dot sight, it’s worth asking what type they really mean. Most people are thinking of a reflex sight, but they might actually need a holographic or prism optic—or even an ACOG style magnified scope.

On this page, my goal is to clear up that confusion, explain the major sight technologies, and help you find the best red dot sight for your setup and budget.

Introduction

In the Marine Corps Rifleman Creed it says, “Without me, my rifle is useless. I must fire my rifle true. I must shoot straighter than my enemy who is trying to kill me. I must shoot him before he shoots me. I will…”

When it comes to optics for shooting enemies before they shoot you at close to mid-ranges, nothing beats a red dot sight.

So, whether you’re looking for an optic for home defense or just something to take out those evil paper targets at the range, a red dot is a great choice.

Optics are one of those accessories you really don’t want to cheap out on. It makes me sick to my stomach when I see a nice rifle with a cheap scope. I wish they would pass a law making it illegal.

On the flip side, if you have a low-end AR-15, it would be stupid to drop $1000 dollars on an optic. The bottom line is you should buy an optic that matches the quality of your rifle.

Types of Red Dot Sights

Reflex Sights

Are the most common type of red dot sight and is what most people are thinking of when they think of a red dot.

These sights operate using a series of mirrors where the dot or reticle is projected forward onto a lens and is reflected back by a mirror, making the dot visible.

Reflex sights come in two distinct flavors and sometimes you may even find a 2-in-1 package where a small exposed reflex is mounted on top or at a 45-degree angle to a magnified tubed reflex. This offers the shooter multiple magnification options.

Exposed Reflex Sights

This type of optic has one mirror that projects the sight dot back at the user. They have no tube and only consist of a small clear window.

These offer the highest eye relief and fastest target acquisition of any type of sight. These are almost never found with any magnification and are highly sought-after for close-quarter or close-range shooting where fast target acquisition is essential.

Tubed Reflex Sights

These sights have two different lenses where the reticle or dot is projected from the rear lens to the front lens. These sights usually are found with no magnification, however, many of them can be found with small amounts of magnification. Tubed reflex sights typically have the most variable functions and can be found in many different shapes and sizes.

This design is significantly more precise and accurate than the other two optics we are discussing today. EOTech has the sole patent on this technology so they are the only producer of a holographic sight. There are some other optic manufacturers claiming to sell holographic sights, but these are usually just reflex sights dressed to appear as holographic sights.

Holographic Red Dot Sights

Holographic sights allow the shooter to acquire targets with both eyes open easily by sporting a clear view of the target through a window.

EOTech sights are very similar to reflex sights but offer higher precision and are usually better known for competitive shooting. The floating reticle allows for angle adjustments automatically, making this sight perfect for shooting on the move or moving from target to target quickly. With that said and considering their market dominance via patent, EOTech sights cost significantly more than exposed reflex sights but offer only a little higher quality and functionality.

Prism Sights

Prism sights are typically shaped like a traditional scope but are significantly more compact and not as long. Prism sights do sometimes come with small amounts of magnification and allow for either an etched or illuminated reticle.

These optics utilize a prism to focus the light and create the sight picture as opposed to mirrors and lenses like traditional scopes do. That’s how they manage to still offer magnification with a smaller and shorter configuration.

They do have some drawbacks, they typically have the shortest amount of eye relief, which means your eye must be closer to the sight to view the picture. This makes target acquisition not as fast as a reflex or holographic, which is the trade-off you are accepting for magnification.

Another drawback is that they only offer small amounts of magnification and will not come close to a full-blown scope. You’ll typically find these in 1x, 3x, 4x, 5x or 6x. Sometimes prism sights are paired with a reflex sight to offer both small amounts of magnification and a quick non-magnified option for target acquisition.

Why a Red Dot Is Worth It (Even for Beginners)

I’m actually a big fan of iron sights, they’re tried and true, but let’s be honest, it’s 2025 and the days of lining up targets with the front and rear sight are over. I mean, even the Marine Corps has moved on from iron sights… that says a lot.

Attaching a red dot optic to your rifle or pistol is the quickest way to increase target acquisition speed, makes shooting more comfortable, and simplifies the shooting process.

Before you start comparing brands, it’s worth learning how to zero a red dot sight properly. A clean zero ensures your optic hits exactly where you aim, whether it’s mounted on a rifle, pistol, or shotgun. Check out our step-by-step guide to sighting in a red dot fast — including the 25-meter zero method used by the military.

For less experienced shooters, red dot sights are more user-friendly than any other type of sight. With a red dot equipped rifle or pistol, you can pass your firearm to say your wife or range buddy who is new to shooting and they will be able to use it very effectively with little training.

My Mission With This Article: In this article, I will explain the differences between reflex, holographic, and prism sights (see above). There are some common misconceptions when it comes to these groups of optics and I want to share some tips to help you find the perfect optic.

I decided to break this review down by price range, so you can quickly find the best red dot sight for the money within your budget. I also share some good retailers, so you know where to get the optic if you decide to pull the trigger.

Understanding 1x Magnification & Magnifiers

Before I get into the type of red dot optics, I’d like to clarify what 1x magnification means. Most red dot scopes come standard as 1x, meaning they don’t offer magnification. This can be changed or augmented however with a second piece called a magnifier.

We have a full post on the best red dot magnifier in 2025. A red dot magnifier is a separate piece of equipment that sits in front of the optic or directly behind the optic and offers magnification for your 1x optics. Usually, these are easily detachable, or they move on a hinge and can be flipped to the side, giving the shooter the ability to use their optic for short-range target acquisition and then switch to magnification quickly for long-range engagement. Most magnifiers come around the 3x range, but you can find some that offer up to 6x magnification.

Like I said above most are non-magnified (1x magnification) and are best suited for close and mid-range shooting. If you’re looking for an optic to increase the range of your rifle, you might want to look for one on this list that offers magnification or check out my ACOGs and Scopes page here.

When Is It OK to Buy a Cheap Optic?

If you’re looking to buy a red dot sight for a .22 caliber rifle or a sight that will simply get the job done you don’t need to spend a lot of money. There are some really great budget options on the market right now, like the Romeo 5.

Most people really don’t need to step out of the under $100 or under $200 category. That said, if you’re looking for a high-end red dot sight for AR-15s, pistols, or other high caliber rifles and are looking for optimal performance, spend some extra cash and buy the best red dot sight you can afford. You’ll thank me later.

You Shouldn’t Put a Cheap Red Dot on a High-Power Firearm

Buying an extremely cheap optic might seem quite appealing, especially if you’re on a tight budget. If your main focus is to simply have something sitting on top of the gun to look tacticool and maybe use once or twice a year, a cheap optic may actually do the trick for you. Unfortunately, if you are going to be putting several hundred rounds down range a cheap optic just simply won’t do.

Some of these cheap optic advertisements will claim they have all the same functions and features as high-end optics and while it may seem like this is true, there will be something lacking.

In the world of optics, you generally do get what you pay for, but that doesn’t necessarily mean you need the latest and greatest optic. There are plenty of great optics in the mid-price range, but don’t plan on getting a quality one for under $50.

Here Are 5 Reasons Why

1. Cheap optics usually have a wide minute of angle (MOA). MOA is a unit of measure for the accuracy of what a shooter may expect the size of groupings to be. You can read more on MOA here. A large MOA means a low amount of accuracy. A large MOA might not be too noticeable when you’re shooting a .22 at close ranges, but when you’re trying to reach out and hit targets at 500 Meters with an AR-15, MOA matters.
2. Another reason to stray far from low budget optics is the crispness of the reticle.
3. Most of the time, cheap optics will have unusually bright or dim dots that are hard to focus on and use in either high or low light situations. Sometimes they even create their own glare and reflections. High-end optics also typically have night vision compatible lighting. This means the lighting is low enough for night vision accessories and goggles to pick up on without damaging them by being too bright.
4. Many cheap optics are also very difficult to get zeroed and sometimes lose their zeroing with time and/or recoil from the firearm they’re mounted on. Speaking of recoil, some optics simply cannot handle the recoil from high caliber weapons and thus result in catastrophic failure for your optics. There are even some cool YouTube videos where cheap low-quality optics shatter and explode.
5. A big difference between high-end optics and low-end optics are their power sources and battery life. Some high-end sights like the ACOGs that are issued to Marines utilize a tritium/fiber optic illuminated reticle that essentially eliminates the need for batteries altogether. Your cheap optics will burn through batteries and lack functions such as auto shut off and power-saving modes. Some high-end optics even have etched sights along with powered reticles to ensure that if you ever run out of energy, you can still use them.

What Features Should You Look for in a Red Dot Sight?

Buying the best red dot sight isn’t just about picking a brand you’ve heard of. It’s about understanding which features actually matter for your firearm and how you plan to use it. Whether you’re setting up an AR-15, a pistol, or a shotgun, the right combination of reticle type, battery life, durability, and mounting options makes all the difference.

1. Reticle Type & Design

The reticle is what you actually see when you aim — and it comes in many flavors. Common red dot sight reticle types include:

• Single Dot: Clean and simple — perfect for beginners or general use. A 2 MOA dot is ideal for precision, while a 4-8 MOA dot is faster for close-quarters.
• Circle-Dot (Bullseye): A small dot surrounded by a larger ring. Great for quick target acquisition and tracking movement — a favorite for AR-15 users.
• Triangle: Precise point aiming at the tip, favored by shooters who prefer a more defined aiming reference.
• Crosshair or Multi-Reticle: Found in advanced optics like the Vector Optics Multi Reticle Red Dot or Aimpoint Red Dot Sight, giving you more flexibility for different shooting styles.

Some modern optics use an etched reticle red dot instead of a fully projected LED, which stays visible even if your battery dies — great for shooters with astigmatism or poor eyesight. Others feature multiple reticle modes or colors (red and green), giving you adaptability across lighting conditions.

Pro tip: If you’re wondering how a red dot sight works (physics-wise), the reticle is projected forward, reflected off a coated lens, and appears to float on your target — maintaining a consistent point of aim regardless of eye position.

2. Battery Life & Power Type

Few things ruin a range day faster than a dead optic. Always check the battery type and expected life before you buy. Common red dot sight battery sizes include:

• CR2032: The most common 3V lithium coin cell — found in optics like the Sig ROMEO5 and many Holosun models.
• CR1632: Smaller 3V lithium battery used in compact red dots such as the Holosun EPS Carry.
• CR1/3N: Used in some older or larger Aimpoint red dot sights.
• LR44: A 1.5V alkaline option sometimes found in tactical or budget models.

Look for optics with automatic shut-off or motion-activation features (like Holosun’s Shake Awake), which preserve power. Many modern sights boast 50,000+ hours of use on a single cell — essentially “set it and forget it” battery life.

3. Durability, Build Quality & Recoil Rating

Durability can make or break your optic — literally. If you’re shooting higher-caliber firearms, check whether the optic is recoil-rated for your platform. Many premium optics like the EOTech EXPS3 or Vortex Crossfire Gen II are tested to withstand 12-gauge or .308 recoil without losing zero.

Look for an aircraft-grade aluminum housing, shockproof construction, and O-ring seals for waterproofing. A hard-coat anodized finish also resists scratches and glare — essential for field use. As someone who’s spent time behind both Aimpoints and budget knock-offs, I can tell you the difference in ruggedness is night and day.

4. Mounting Options & Footprints

You can’t use your optic if you can’t mount it. Red dot sights come in several footprints and mounting systems. The most common red dot sight mounting options include:

• Picatinny / Weaver Rails: Standard on most rifles and carbines — always check compatibility.
• Pistol Mounting Plates: Micro-dots like the Holosun 507K or EPS Carry use RMSc or K-series footprints.
• Universal Red Dot Mounts: Great for older pistols like 1911s — some even work without drilling.
• Riser or Co-Witness Mounts: Allow you to align the optic with backup iron sights or adjust your sight height for comfort.

Always confirm your pistol red dot footprint chart or rail dimensions before buying — it’s one of the most common buyer mistakes. I’ve seen shooters drop $400 on a sight only to realize it doesn’t fit their slide cut.

5. Size, Weight & Field of View

A red dot sight’s size directly affects how it handles. Compact models like the Holosun EPS Carry or Trijicon RMRcc keep pistols slim and snag-free. Larger optics like the Vortex Strikefire II or Sig ROMEO-M17 offer a wider field of view and easier tracking for rifles or carbines.

The key is balance — a lightweight sight that doesn’t throw off your weapon’s center of gravity, but still gives you enough window size for fast acquisition.

6. Purpose & Intended Use

Before buying, ask yourself: What are you going to use it for? Range fun? Home defense? Duty rifle? Each role favors different features:

• Home Defense / Tactical: Choose a bright, durable optic with quick-on illumination (e.g., EOTech EXPS3, Holosun 509T).
• Competition / Range: Look for a multiple-reticle red dot sight or larger window for fast follow-ups.
• Hunting: Go for an etched or illuminated reticle with excellent battery life and weather sealing.
• Everyday Carry (Pistol): Compact, lightweight, and motion-activated models shine here.

There’s a saying among Marines — “Mission drives gear.” The same applies here. Match your optic to your mission, not the other way around.

7. Price vs. Performance

There’s an old saying that still holds true: “The optics on your firearm should cost about as much as the firearm itself.” It’s not gospel, but it’s a good rule of thumb. A cheap optic on a quality rifle is a waste; a $1,000 optic on a bargain gun is overkill. Find the balance point that fits your firearm and your skill level.

Red dots have come a long way — you can now find models under $200 that rival mid-tier optics from a few years ago. Brands like Vortex, Holosun, and Sig Sauer offer lifetime warranties and near-bombproof construction, so you don’t have to overspend to get reliability.

Best Red Dot Sights for the Money (2025 Picks)

1. Sig Sauer Romeo 5 (Best Value)

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x20mm multi-coated with Spectracoat and anti-reflection
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: This is hands down one of the best red dot sights on the market today and in my opinion, is probably the best value of any sight you can buy. The Romeo 5 is a fantastic little budget red dot sight , and you don’t always get things from Sig Sauer that are affordable!

Along with offering a very clear sight picture, this beauty has some standout features for a sight in this price range. It has motion-activated illumination, which means any movement or vibration will cause the sight to “wake up” and automatically turn on. This functionality is nice because that means if you accidentally forget to shut the sight off, it will automatically turn off after 15 minutes. That means you won’t have a dead battery when you need the sight most because you forgot to shut it off.

The Romeo 5 is meant to be used in co-witness with other Sig optics and even comes with the mounting hardware to achieve this. All in all, Sig always delivers a great product for an arguably high price tag. With this price tag, however, comes the Sig Sauer Guarantee warranty and of course, the bragging rights of using a Sig product!

Pros

• 2 MOA dot
• 10 illumination settings
• Motion activated

Cons

• Proprietary mount required
• Mount system is fairly high

This is also one of the most durable red dot sights out there! Check out the video below where they actually test and torture the Romeo 5.

2. EOTech 512 Holographic Sight (Editor’s Choice)

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x20mm with anti-glare coating
Optic Type: Patented Holographic
Reticle: Holographic 1 MOA dot with 68 MOA ring

My Review: EOTech is a legendary brand in the firearms accessory industry, and as stated above EOTech has a patent on holographic sight technology, which is hands down the best.

If you buy an EOTech sight most likely you’re going to love it, but I want to let you know a couple of things before you purchase one of their optics. After doing a bit of research, I have found that many of their customers, including the US government, have had some misfortune in dealing with them. Of course, technical difficulties in new technology are bound to happen and mistakes can be forgiven, but I wanted to give you the facts and let you decide what to do what you want with them. You can read the lawsuit news here .

So long as you are shipped a brand new fully functioning optic, you will be satisfied. There is no other brand out there that offers this technology. Eye relief is unmatched by its competitors and the free-floating reticle is perfect for acquiring targets no matter the angle you are using to peer through the window. My personal usage of EOTech sights have always been positive. I love that this sight runs on two AA batteries that are very easy to replace.

EOtech sights are commonly used by law enforcement, SWAT teams, and military personnel. I choose this model because I feel it is the best value of all their sights and seems to have the highest overall reviews. For those of you who want to spend even more on an even higher-end optic, EOTech has much more expensive versions of this sight that include a plethora of added features.

Pros

• Replaceable battery
• Excellent sighting ring & dot
• 1 MOA dot

Cons

• 1/2 MOA click value
• Low battery life

3. Aimpoint PRO Patrol Rifle Optic

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x20mm fully multi-coated
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: The Aimpoint Pro Patrol Optic was designed specifically for law enforcement and police use. It doesn’t have quite as many features and settings as the CompM4 used by the US Army, but it still features a very crisp 2 MOA red dot and an insanely clear field of view.

The Aimpoint Pro is about half the price of the CompM4 and is overall a better value. That said, CompM4 does have more features, including 3 more night vision settings and 3 more day time settings. If you think you might be interested in the CompM4 you can read more about it in the under $1000 section of this review.

The Aimpoint Pro always on function is especially handy for those of you who may need to deploy your firearm at a moment’s notice. This scope was made for Law Enforcement Officers (LEOs) and military personnel in mind.

If you’re looking for the best red dot sight for the money to attach to an AR-15 or other similar rifles I would say it’s a toss-up between the Aimpoint Pro and the EOTech red dot optic listed above. The Aimpoint Pro is one of the highest-rated optics out there. I have used this optic and the EOTech listed above and you’re going to be happy either way. They both have slightly different features and you need to decide which ones you want.

I always like to talk about the downside of an optic because if you go to Amazon and read reviews it’s almost all praise and people saying how their rifle is shooting like a dream. Just beware that some customers who purchased this optic from certain sellers on amazon received a defective unit or returned unit that was once and may still be defective. So, if you do decide to buy an AimPoint, just be sure that it’s actually the AimPoint company you’re buying it from. So long as you get one that lives up to its name, you are guaranteed to love it.

Downsides aside, this is one of the best all-around tubed reflex sights with innovative battery saving technology, capable of remaining active for three years continuously with only a single battery! Three years is a long time and you can be sure these optics will last as long as their battery life due to an extremely durable and well built anodized aluminum shell and waterproofing capable of withstanding 150ft of submersion.

The package here includes everything you need to get shooting out of the box such as the Aimpoint Modular QRP2 mounting hardware, spacers, flip covers, and is compatible with night vision.

Pros

• 2 MOA dot
• Long battery life
• Waterproof 150 feet
• Modular

Cons

• Large tube for a red dot
• 1/2 MOA click value
• Target acquisition slower than a single-pane

Here is a video review of the optic. I recommend skipping to 0:45 in the video.

4. Vortex Defender-CCW Review

Check Price on Amazon | Buy on OpticsPlanet

The Vortex Defender-CCW is Vortex’s latest enclosed-emitter style red dot built specifically for everyday carry. It replaces the Vortex Venom and Vortex Viper models with major updates to battery access, lens design, and mounting compatibility. In this updated Vortex Defender CCW review , we cover the current Vortex Defender CCW price , specs, and how it compares to the Vortex Defender-ST and Defender-XL .

Vortex Defender-CCW Specs (2025 Update)
Magnification / Objective	1×24 mm
Reticle Options	3 MOA / 6 MOA Red Dot
Optic Type	Micro Reflex Enclosed Emitter
Battery Type & Size	CR1632 Top-Load Design
Battery Life	Up to 9,000 hours (approx 1 year real-world)
Battery Replacement Tool	No tools required – thumb slot for easy change
Housing Material	7075-T6 Aluminum (ultra-durable)

Brightness Settings	10 Manual + Auto Mode + Motion Activation
Weight	Approx 1.0 oz (28 g)
Warranty	Vortex VIP Lifetime Warranty (USA)

My Review: The Defender-CCW’s enclosed-emitter design protects the lens from dust and debris better than open reflex optics like the old Venom. It uses a CR1632 battery that loads from the top, making battery changes simple without re-zeroing — one of the most-searched questions (“ Vortex Defender CCW battery change instructions ”) is now a non-issue. The optic is built like a tank but remains feather-light, and the aspherical lens delivers zero distortion across its wide field of view.

Compared to the Vortex Defender-ST and Defender-XL , the CCW version is optimized for concealed-carry pistols (think Glock 19, Sig P365, and Springfield Hellcat). It shares the same electronics and Defender CCW manual as the larger models, and its battery life is nearly identical in real-world testing — typically 9 months to 1 year depending on brightness. Users on Reddit have also confirmed simple battery replacement using just a coin.

Model	Best For	Footprint	Battery Type	Dot Sizes	Approx Price (USD)
Defender-CCW	Concealed Carry / Micro Pistols	Shield RMSc	CR1632	3 MOA / 6 MOA Red Dot	$249 – $349
Defender-ST	Standard Pistols / Tactical Use	DeltaPoint Pro	CR2032	3 MOA / 6 MOA Red Dot or Green Dot	$379 – $449
Defender-XL	Competition / Rifle Platforms	DeltaPoint Pro	CR2032	2 MOA / 5 MOA / 8 MOA Red Dot	$459 – $499

Vortex Defender CCW Compatibility: The optic fits most RMSc-cut slides, including Glock 43X MOS, Glock 48 MOS, SIG P365, Springfield Hellcat, and Canik METE MC9. For larger frames like Glock 19 MOS or FN 509 Tactical, use the included shim plate to align sight height with Defender ST/XL. It’s also compatible with most Picatinny adapter plates for shotguns and PCCs.

Vortex Defender CCW Battery Life & Replacement Tips: Expect around 9,000 hours of runtime at medium brightness. Replace the CR1632 battery once a year for best performance — just twist off the top cover with your fingers or a coin. No tools are required, and you won’t lose zero thanks to its top-load battery tray.

Pros

• Top-loading CR1632 battery (no re-zero)
• 9,000-hour battery life at mid brightness
• Rugged 7075-T6 aluminum body
• Fully enclosed emitter design for reliability
• Compatible with Shield RMSc mounts
• Available in Red Dot or Green Dot versions

Cons

• Shorter battery life than some CR2032 competitors
• No solar backup or auto-shutoff timer customization

Note: The Defender series officially replaces the Vortex Venom and Viper lines, which are discontinued. The Defender-CCW delivers the same footprint and performance with modern upgrades in optics, battery design, and durability.

5. Aimpoint ACRO P-2 (Best Enclosed-Emitter Red Dot)

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1× magnification, 3.5 MOA red dot, fully multi-coated glass
Emitter Type: Enclosed sealed emitter
Battery Life: 50,000 hours (5+ years) on CR2032 battery (included)
Construction: Hard-anodized aluminum, waterproof to 115 ft (35 m)
Weight: 0.31 lbs (140 g)
Footprint: Aimpoint ACRO mount interface (plates available for Glock MOS and RMR adapters)

My Review: The Aimpoint ACRO P-2 is the current gold standard for enclosed-emitter red dots. Built like a tank, it’s designed to survive the recoil and environmental abuse that destroy lesser optics. The 3.5 MOA dot is crisp, daylight-bright, and remains visible even through tinted lenses or under night vision. The ACRO P-2’s sealed emitter keeps mud, rain, and lint off your lens — a big advantage over open-emitter pistol optics like the Trijicon RMR Type 2.

Battery life stretches beyond five years, and its submersible 115-foot rating makes it equally suited for duty pistols, carry setups, and rifle mounts. It’s heavier than micro dots like the Holosun 507C, but the added durability and peace of mind are worth the trade-off for serious users.

Feature	Aimpoint ACRO P-2	Trijicon RMR Type 2
Emitter Type	Enclosed (Sealed)	Open (Exposed)
Battery Life	50,000 hrs (CR2032)	4,000 hrs (CR2032)
Submersible Depth	115 ft / 35 m	66 ft / 20 m
Footprint	ACRO Interface (Glock MOS plates available)	RMR Footprint
Weight	0.31 lbs	0.12 lbs
Ideal For	Duty / Carry / Enclosed Reliability	Lightweight EDC / Competition

Popular Article: Best Red Dots for Shotguns (Updated 2025)

Pros

• Fully enclosed emitter — no dust or rain interference
• 50,000-hour battery life
• Exceptional Aimpoint durability
• Waterproof to 115 ft (35 m)
• Perfect fit for Glock MOS and ACRO mounts

Cons

• Heavier than open emitter alternatives (e.g., RMR Type 2)
• Higher price tag (~$600+)
• Proprietary mounting interface requires adapter plate

6. Holosun HS510C Red Dot Optic

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x
Optic Type: Exposed Reflex in a holographic designed shell
Reticle: 2 MOA standard red dot with 65 MOA Ring

My Review: This thing really gives EOTech holographic sights a run for their money and is a great value for those of us who don’t have EOTech level budgets. It has the ability to toggle the dot and ring which is a huge advantage over the early EOTech models but at a much cheaper price.

With 50,000 hours of battery life and a beautiful titanium alloy shell, this sight is a serious contender, especially if you’re not looking to spend a lot.

Here’s a nice video explaining this optic in greater detail:

Pros

• 2 MOA dot
• 65 MOA Circle
• Motion activated
• 12 light settings
• Solar panel

Cons

• Integrated mount means use theirs
• Battery not easy to get to

7. Sig Sauer Romeo 1

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x with multi-band high light transmission lens
Optic Type: Exposed Reflex
Reticle: 1 MOA standard red dot

My Review: You know I’m a huge fan of Sig Sauer already and for good reason as they always deliver incredibly high-quality products that seem to be exactly what the doctor ordered if you were to get a prescription for shooting things accurately that is.

The Romeo 1 Mini Reflex embodies everything Sig Sauer stands for. They have a super tactical appearance while still maintaining a level of elegance and style that matches with pretty much anything, the sight itself is nearly indestructible as Sig knows well by now that their products are being bought to be abused, and as always, you get crystal clear Sig Sauer glass with all the goodies we love from Sig Sauer.

The Romeo 1 comes with the MOTAC technology, which essentially just means it gets turned on when you move it around, meaning you’ll save tons of battery since the illumination automatically turns off when it detects no movement at all.

The window is an orange frosted 30mm lens with the Sig Sauer proprietary Spectracoat and since this is an open based red dot, it has unlimited eye relief and contains no magnification. The dot you get is a 3 MOA red dot with configurable illumination levels and is all powered by an easy to remove top-loading CR1632 battery.

The particular package I’ll send you to is both ready to be mounted on rifles and pistols, with the included pistol adapter kit that basically just gives you dovetails and mounting plates.

There is an older version of this red dot sight that comes with a green lens instead. Most of the specs are the same but I believe the newer version has better battery life and in my opinion, it looks a bit sharper and I just personally prefer the newer version. The new version is under model code SOR11005 and the older version is under model code SOR11001.

Pros

• 1 or 3 MOA dot
• Co-witness through the lens

Cons

• Expensive
• Rail mount not included

8. EOTech EXPS3 HWS (Best Holographic Sight)

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1× magnification, 0.5 MOA adjustments, 1 MOA dot / 65 MOA circle reticle
Type: True holographic sight
Brightness Settings: 20 daylight + 10 night-vision modes
Battery Life: ≈1,000 hours at setting 12 (Reticle brightness dependent)
Mount: Quick-detach Picatinny rail mount included
Night Vision: Gen I–III+ compatible
Construction: Metal housing, waterproof & fog-resistant

My Review: The EOTech EXPS3 HWS remains the professional benchmark for holographic weapon sights. Its floating 1 MOA dot and 65 MOA ring reticle deliver rapid target acquisition without sacrificing precision. Unlike reflex LED sights, EOTech’s laser-driven holographic reticle stays true to point of aim from virtually any angle, making it ideal for both CQB and mid-range engagements. The EXPS3’s short base mount and side-loading CR123 battery keep the profile low and installation simple on crowded rails.

There are several EXPS3 variants — the EXPS3-0 (single dot), EXPS3-2 (two-dot BDC), and EXPS3-4 (four-dot reticle). Each uses EOTech’s proprietary 65 MOA ring for faster bracketing and offers full NV compatibility. With a rugged metal housing and a field of view around 120 feet at 100 yards, the EXPS3 is still the go-to optic for military, law-enforcement, and professional shooters who demand speed and durability.

9. Vortex Strikefire II

Check Price on Amazon

 

Optical Specs:  1x tube-style red dot
Optic Type:  Red dot
Reticle:  4 MOA dot

My Review: This is a tube-style red dot scope. It is ideally suited to carbines and short-barreled rifles. As of this writing braces are again legal in the United States (this could change in a minute’s time), so the scope is excellent for braced pistols as well.

The scope is parallax free which means it is best suited for short to mid-range shooting. Past 200 yards, you really need parallax correction. 

Also, the 4 MOA dot covers 4 inches at 100 yards. Reaching out to 200 yards, that dot covers a whopping 8 inches. You could hide and entire varmint inside that circle.

The scope ships with a canteliver mount. This raises the scope more than a set of low rings. If you mount it to a rail already elevated a good bit above the barrel, you are looking at a lot of elevation adjustment to lower the dot to be on target.

Adjustments are 1/2 MOA.

All the above adds up to say this is not a precision work scope. Red dots in general are not meant for superior accuracy.

So, if you are looking for a CQB or 3-gun speed tournament carbine, this is a good choice.

Pros

• Vortex warranty
• 10 light levels
• 30mm tube
• Long battery life
• High light transmission

Cons

• Slower targeting 
• Needs higher mount rings
• Single-point ring attachment
• 1/2 MOA click value

10. Meprolight Self-powered Bullseye

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x30mm
Optic Type: Exposed Reflex
Reticle: 4.3 MOA, 5.5 MOA, Bullseye, or Triangle reticle options available

My Review: This optic is built like a tank but lacks the weight of one, while still providing a nice seamless design. It requires no batteries and no on/off buttons, so it’s always on and always ready to rock and roll. It’s no wonder the Israeli Special Forces love to use this reflex sight, it is by far one of the most dependable sights I have ever reviewed.

Ultra-bright environments or utter darkness isn’t going to halter this sight as the brightness of the display and the intensity of the dot will automatically adjust according to the light situation.

These were designed to be as tough as possible, facing imminent combat situations and to be used in tandem with magnifiers like the MEPRO MX3. The self-illuminating reticles are using fiber optic technology when ambient light is available and tritium during low light situations to ensure your reticle is bright and crisp no matter where you are.

If you have the extra money, throw it at this thing and go to bed at night calmly knowing that this sight will probably outlive you and will still be shining like the day it was new.

Pros

• No battery needed
• Choice of reticles
• Magnifier  capable
• Tritium illumination; visible at night

Cons

• Needs ambient light for best results
• New tech for a red dot
• All reticles are large

11. Aimpoint QRP2 CompM4

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x25mm with Aimpoint Proprietary protective and anti-glare lens coatings
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: The Aimpoint CompM4 is one of the top reflex sights out there so long as you’re willing to pay top dollar for it. At $850, it’s not the most expensive option you’ll find but it’s certainly not cheap. What you get, though, is a buy once cry once experience leaving you with optics that will shine bright longer than you’ll likely live!

These sights come with incredible battery life and are actually optimized for night vision with special NV settings. The mounts that are included allow this sight to be functional atop almost any weapons system and mounting this optic is incredibly easy. If you’re looking for optics to shoot at 300m or less, this is probably your best option. AimPoint also gives incredible warranties with each of its products in the off chance something does go wrong, so there really isn’t much to worry about investing in this optic!

Included in the package is the KillFlash anti-reflection device with Milspec lens covers.

Pros

• 2 MOA Dot
• Easy replace batteries
• AA batteries
• Long battery life
• Waterproof 150 feet

Cons

• 1.5 MOA click value
• Target sighting slower than single-pane
• Knob on side gets in way
• Low light transmission

12. Trijicon MRO-C Patrol

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x25mm with Trijicon proprietary lens coatings
Optic Type: Tube Reflex
Reticle: 2 MOA multi-axis adjustable red dot

My Review: Trijicon makes good stuff, period, so I don’t think I really need to say anything more regarding the quality you’ll get. They’re the best, simply put, and they will not disappoint no matter the model you choose, so long as you get the right one for your set up.

Now, Trijicon is usually synonymous with their ACOG line up and it’s not often people give them credit for their other optics. The MRO-C is a hefty looking red dot but it doesn’t just look hefty, this is by far one of the most durable and battle-ready red dots you could ever spend your hard-earned money on. If you’re the type of person to save up and only buy the best of the best, the Trijicon MRO-C should be on your shopping list.

The MRO-C utilizes a 25mm lens to project a none magnified 2 MOA red dot with infinite eye relief. The dot is powered by a lithium CR2032 that is included in the box and being used at illumination setting day 3, you should get roughly 5 years of battery life, so perhaps hold off on stocking up on batteries for this crazy thing!

Furthermore, this red dot is built to give you options. This isn’t a selfish standalone unit but instead, it’s ready to work together in co-witness and even comes with a few mounting options for use with other magnifiers. Speaking of options, you can easily revert to iron sights or whip out a larger scope since this comes with a quick detach mount that literally takes just a couple of seconds to remove completely.

The Patrol package grants you a fancy Tenebreax KillFlash anti-reflection hood that ensures no one can pick you out of the brush during the day from a little glare. The MRO-C Patrol is rated for just about everything, including shotguns and like I said before, it’s one of the toughest made red dots on the market today and since it’s military-grade waterproof, it’s capable of surviving submersion all the way down to 100ft.

Pros

• 2 MOA dot
• Very long battery life
• Quick release mount
• Suited for heavy recoil
• Waterproof 100 feet

Cons

• Tube style
• Mount is extra
• Mount is very high

13. Trijicon RMR LED Type 2 Sight

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x22mm multi-colored wide-band light transmission lenses
Optic Type: Exposed Reflex
Reticle: LED 3.25 MOA in the RM01 or 6.5 MOA found on the RM02

My Review: This is the industry leader in exposed reflex sights. No other reflex is as small, light, durable, and has an automatic light-adjusting lens. This almost fits in the under $450 category but unfortunately, the prices you’ll find it at do not include mounts. Mounts for this sight can be very expensive depending on whether or not you are mounting this to a pistol or rifle.

Battery life is pretty good at roughly two years, as expected from Trijicon and the housing shape is very unique, offering a fantastic looking optic in an incredibly small form factor. The RMR is constructed from forged aluminum alloy with the intent of being resistant to impacts but surprisingly still only weighs a minuscule 1.2 ounces.

Anything from Trijicon is going to be rather expensive, but if you can afford it, Trijicon has been long known to be one of the top military-grade optical manufacturers and continues to provide above and beyond functionality and durability. I’d go as far as to say Trijicon offers the absolute toughest and most rugged optical solutions you can get your hands on.

Just like many of the other major brands, Trijicon is suffering from the market being flooded with knock offs and shady resellers. Please ensure you are purchasing a real Trijicon reflex sight, their packaging has identifiers on it to prove authenticity.

Pros

• Low profile
• Fits many semi-auto slide cutouts
• Good battery life
• Waterproof 66 feet

Cons

• Mounting kit needed for some RMRs
• 3.35 MOA dot
• 1 MOA click value

For concealed carry and subcompacts, an enclosed emitter solves the debris and moisture issues common to micro open-reflex dots.

14. Holosun EPS Carry (Best Compact Enclosed Emitter)

Check Price on Amazon

Optical Specs: 1× magnification, 2 MOA red dot (EPS Carry-RD-2 configuration)
Emitter: Fully enclosed, sealed housing
Battery Life: Up to 50,000 hours (CR1620)
Brightness: 12 settings (10 daylight + 2 NV)
Footprint: RMSc / “K-series” pattern; includes RMSc-to-K adapter plate
Housing: 7075-T6 aluminum, built-in rear notch, IPX8 rated
Dimensions / Weight: ~1.62″ L × 1.07″ W × 0.95″ H; ~1.44 oz

My Review: The Holosun EPS Carry is the micro-enclosed pistol optic a lot of shooters were waiting for. By sealing the emitter inside a 7075-T6 aluminum housing, it avoids the dust, rain, and lint issues that can obscure open-reflex dots on carry guns. The dot is crisp, the glass is clear, and the controls are simple. Between the side-loading battery tray, Shake Awake motion activation, and long runtime, it’s an easy upgrade over legacy micro-reflex designs while staying compact enough for subcompacts like the P365, G43X/48 MOS, and similar slides.

This RD-2 variant uses a 2 MOA red dot, but green-dot versions and MRS reticles exist if you prefer different aiming references. The ultra-low optical height helps retain usable factory irons on many pistols, and the included adapter plate expands slide compatibility. For EDC or duty-adjacent carry, the EPS Carry delivers reliability and value well above its price class.

15. Vortex Optics Sparc 2

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x22mm fully multi-coated
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: This optic is basically a high grade “wannabe” with mid-grade technology. It is definitely usable and isn’t a terrible option for budget seekers, however, don’t expect mil-spec grade quality.

With that said, Vortex rarely disappoints and for the price you pay here, you are getting some pretty excellent value. The site is constructed of machined aircraft-grade aluminum allowing it a lightweight feel but heavy-duty performance and it’s waterproof, so it checks the boxes for mid-range durability.

I found this optic to be extremely easy to adjust and the rear-facing controls are both intuitive and easy to use quickly . Cycling through the 10 brightness settings is a breeze, but I will comment on the brightness settings, as I thought the highest setting was so high that is was unusable. The rest of the settings are fine and some of them are night-vision compatible. The reticle is very crisp with optics of higher quality than I would expect at this price point.

The included adjustable mounting system is extremely easy to use and I really liked how the sight and mounting hardware still allow for the use of iron sights.

Pros

• 2 MOA dot
• Easy replace AAA battery
• Vortex warranty
• Can co-witness in some guns

Cons

• High mount
• 1 MOA click value

16. Primary Arms MD-ADS Red Dot

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x25mm
Optic Type: Tube Reflex
Reticle: 2 MOA Microdot

My Review: Primary Arms is one of the best mid-range priced optics manufacturers and they really hit this one home. At this price, you can’t possibly expect AimPoint quality and surely you won’t find it on the MD-ADS.

Upon first getting this sight, you’ll notice an overall cheap feel of the components but don’t let that discourage you, that’s how Primary Arms managed to deliver such a crisp dot and high-quality glass at such a bargain of a price. They put the money where it matters most. If you can’t afford a top-notch brand, this sight will bring you just as much functionality and nearly as much durability for a fraction of the cost.

This thing has an insane battery life, rated at 50,000 hours with a single saucer battery and also an insane built quality, consisting of hard-coated anodized aircraft aluminum that is both IP57 water and shock-resistant.

Pros

• Short tube
• Low mount
• 2 MOA dot
• Long battery life
• Lifetime warranty

Cons

• Target sighting not as fast as single-pane
• .5 MOA click value

17. Sightmark Shot Plus

Buy on OpticsPlanet

 

Optical Specs: 1x25mm
Optic Type: Exposed Reflex Holographic look-alike
Reticle: Four integrated options: 3 MOA dot with 50 MOA circle, 5 MOA standard dot, 3 MOA with 50 MOA crosshair, 3 MOA with 30MOA circle/crosshair

My review: For all of you who want a fancy little holographic look-alike for an affordable price, the Sightmark SM26008 is the answer. No, it’s not even close to mil-spec and no, it’s not actually a holographic sight, however, it is cheap and it does work, all while adding a bit of tacticoolness to your rifle.

Personally, I do like it. I am fairly against spending over a thousand dollars to get a 1x optic and I think many people share that sentiment. Sightmark capitalized on the market and gave us a super cheap but usable option. All around, it isn’t great, but it’s suitable for the price and will likely work well for most people. Just don’t get it too cold, as it will fog up and you’ll be worse off than you would with no sights at all!

This sight actually comes with a lot of features that I was surprised to see in a budget option, including the choice between red and green reticle colors, tactful digital controls, a quick detach weaver mount, 5 brightness settings, a 1000 hour battery life rating, and IPX4 water resistance. The housing is a cast-aluminum that, although not being as good as EOTech, is fairly sturdy and protects the optics from slight bumps and falls.

Pros

• Moderate battery life
• Water resistant (rain)
• 4 reticle choices

Cons

• High mount
• No co-witness
• 5 light settings
• 1 MOA click value

18. Primary Arms SLxZ Advanced Red Dot

Buy on OpticsPlanet

Optical Specs: 1x30mm
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: This optic, like most from Primary Arms, has a great reputation and is offered at a great price. The battery life is nearly unbeatable when it comes to budget optics and the flip caps are of high quality, something many manufacturers cheap out on!

The design is very lightweight but still very durable, consisting of 6061 aluminum with a hard-anodized finish. These have a rather impressive 14,000-hour battery life operating on a 1/3N button battery.

It won’t come out of the box with a mount, so you’ll need to purchase one if you don’t already have one. Luckily, this scope is under 150 dollars so purchasing a mount should keep you under $200 still.

Pros

• 30 mm tube
• 2 MOA dot
• Great battery life
• Waterproof (1 meter)

Cons

• Fairly long tube for a red dot
• Target sighting not as fast as single-pane
• 1 ring mount location
• 1/3 MOA click value

If you want a budget-friendly tube-style red dot with long battery life and simple controls, this next pick is a strong value.

19. Vortex Crossfire Gen 2 (Best Budget Red Dot)

Check Price on Amazon

Optical Specs: 1× magnification, 2 MOA green dot
Brightness Settings: 11 total (9 daylight + 2 NV)
Battery Life: Up to 50,000 hours (CR2032 battery)
Mounting: Low mount and 1/3 co-witness mount included
Material: Hard-anodized aluminum housing / sealed O-rings for waterproof protection
Weight: 5.2 oz (147 g)

My Review: The Vortex Crossfire Gen 2 is the newest iteration of one of the most popular budget red dots ever made. Vortex refined the glass, housing, and controls while retaining the brand’s “no-nonsense” simplicity. With its bright 2 MOA dot, 50,000-hour battery life, and lightweight aluminum body, this optic covers hunting, defensive carbines, and range plinking without adding bulk or cost.

Unlike many economy dots, the Crossfire Gen 2 ships with both a low and a skeletonized 1/3 co-witness mount, giving shooters flexibility across rifles, shotguns, and PCCs. The multiple anti-reflective coatings produce a clearer image than the original Gen 1 version, and the O-ring sealed construction keeps dust and moisture out in harsh environments. Vortex’s unconditional VIP lifetime warranty seals the deal—this optic is one of the few sub-$200 red dots you can truly trust long-term.

Specification	Vortex Crossfire Gen 2
Magnification	1× (non-magnified)
Reticle	2 MOA Green Dot
Battery Life	≈ 50,000 hours (CR2032)
Brightness Settings	11 (9 Day + 2 NV)
Housing	Hard-anodized aluminum, O-ring sealed
Mounting Options	Low + 1/3 Co-Witness Mount Included
Length × Height × Width	2.5 ″ × 2.5 ″ × 1 ″
Weight	5.2 oz (147 g)
Warranty	Vortex VIP Lifetime Warranty

Crossfire Gen 2 vs Gen 1 Comparison

Feature	Gen 2	Gen 1

Pros

• Outstanding clarity for a sub-$200 optic
• 50,000-hour battery life with NV compatibility
• Includes both low and 1/3 co-witness mounts
• Waterproof and shockproof construction
• Covered by Vortex VIP Lifetime Warranty

Cons

• Brightness dial could use more textured grip in gloves
• Green dot option costs slightly more than red
• Limited magnifier compatibility due to short tube length

20. Aimpoint Micro T-2 Sight

Check Price on Amazon

Buy on OpticsPlanet

Optical Specs: 1x25mm with Aimpoint Proprietary protective and anti-glare lens coatings
Optic Type: Tube Reflex
Reticle: 2 MOA standard red dot

My Review: So long as you don’t find yourself with a knock off, you are guaranteed to be satisfied. Your bank account won’t be so thrilled at first, but it’s a buy once cry once kind of deal.

No need to worry about eye relief, optic washing, starbursting, optical rings, etc. This sight is optimized to be used on any of its several brightness settings and is compatible with all night vision gear. These are sights that are trusted by our men and women on the front lines.

Of course, as with most Aimpoint products, you’ll be getting that 50,000 battery life rating we know and love and no, water won’t be impeding that as this unit is capable of surviving submersion all the way down to 80’. These are night-vision friendly and include the Aimpoint advanced optical clarity lenses.

Overall, these are some of the best reflex red dots on the market. They’re so good that many other manufacturers use them as a sort of benchmark, judging and reviewing their own products off of this particular model.

BUYER BEWARE!

You may have noticed that I have mentioned some of the major brands in optics have stark rivals with counterfeiting and resellers. You absolutely must take caution when purchasing optics online. On Amazon, you will almost always have a choice to purchase optics from multiple sellers. Please ensure the seller is trusted and is shipping the optics from somewhere that makes sense. For many optics on this list, they are manufactured in the US. If optics are being shipped from another country, you should be extremely wary of its legitimacy. Further, many of the name brand optic manufacturers like Aimpoint, Trijicon, Vortex, and EOTech have extensive instructions and product databases located on their websites. They are aware of counterfeits in their midst and offer you tools to identify these counterfeiters.

Here are some of the pages you can resort to:

Our Review & Testing Methodology

At Marine Approved, we don’t just recycle manufacturer specs or Amazon reviews — we actually get hands-on with the gear whenever possible. Our goal is to give you information you can trust, based on real-world use and honest performance testing.

How We Select Optics

Each red dot sight on this list was selected through a mix of field testing, technical evaluation, and user feedback. We start by narrowing down models that have proven track records for reliability and verified performance. That includes both combat-proven optics like the Aimpoint and EOTech series, and newer contenders from brands like Holosun and Vortex.

Hands-On Testing

When possible, our team (made up of current and former service members and experienced shooters) tests optics on a variety of platforms — including AR-15 rifles, PCCs, and compact handguns. We focus on:

• Clarity and Reticle Precision: How crisp and distortion-free is the sight picture?
• Durability and Shock Resistance: Can it handle real-world recoil and range abuse?
• Battery Life and Power Management: Does it meet or exceed advertised specs under normal use?
• Zero Retention: Does it hold zero after hundreds of rounds or rough handling?
• Ease of Use: Controls, brightness settings, mounting, and compatibility.

Supplemental Research & User Data

We also study verified buyer data, professional law enforcement/military reports, and community feedback from trusted sources — not just Reddit threads. This helps us cross-check our field impressions against long-term reliability reports.

Transparency & Updates

Optics technology changes fast. That’s why this guide is updated annually — and sometimes mid-year — to reflect the newest releases, manufacturer updates, and reader feedback. If we recommend something, it’s because we’d use it ourselves or trust it enough to put it on one of our rifles.

Bottom line: Our goal is to help you make confident, informed decisions — whether you’re mounting your first red dot or upgrading a professional-grade setup.

Frequently Asked Questions

This list is not conclusive of all red dot sights available but is more so a great place to get a feel for what this market has to offer. There are so many different firearms and situations that it would be impossible to review each and every optic for each and every situation. As always, research the optic completely to ensure you are capable of using it on the firearms you own and that there won’t be an issue with eyesight blurring the reticle.
