20 Best AR-15 Scopes for the Money in 2019 (Listed by Price)

The Situation: You finally pulled the trigger and bought that AR-15 you’ve been daydreaming about.

You’re super excited to finally get out for some range time, but after sending a few rounds down range something just doesn’t feel right.

It’s not the tactical stock, it’s not the muzzle break, it’s not the foregrip. What could it be?

You plink a few more demonic paper targets trying to consider what could be missing when you hear the faint metallic pings. They sound like they’re coming from over 500 meters out!

You realize the guy down range is nailing the long distance targets with an AR that is built just like yours! What’s his secret? What does he have that you don’t?

Then you see it. Those beautiful curves. Those shiny lenses. Those sexy flip up covers. That’s it! You need a new scope for your AR-15.

So, you speed home and hop on the Google box searching for the best AR-15 scope for the money within your price range. An overwhelming sensation ensues and soon you are hours deep in reading thousands of reviews over hundreds of scopes.

There are so many options, how could you ever choose just one? These things are expensive, so God forbid you pull the trigger on one and it turns out to be a lemon.

I’ve been there, so let me help you by first explaining what to look for and what to expect and then I’ll list out some of my favorite choices in variable price ranges that should help you to find exactly what you’re looking for!

Scope for AR-15s Buying Guide

First and foremost, if the scope buying process is stressing you out, sit back in your chair and relax. Look through your favorite Field and Stream magazine and ponder the meaning of the life beyond your boom stick.

What do you need a new AR-15 scope for? Are you simply looking to take out those evil paper targets at the range? Are you planning to destroy your enemies in competitive shooting? Are you building a new rifle to gun down those furry little critters your wife or girlfriend loves? Are you planning to bust this sucker out at a meat shoot? Is it your life long goal to see how far a .223 is capable of flying?

You must dial in the scope of the mission before you even think about buying a new AR-15 scope. No scope will handle every job perfectly so really think about how you’re going to use this bad boy.

Home defense? Go ahead and stop reading here and instead pop over to my red dot sights buying guide as you won’t need a scope for good ol’ close quarter combat situations.

Tips to Find the Right Magnifying Tube Thingy

In this part of the guide, we’ll discuss things you should know before you start searching for a suitable scope for AR-15s. If you are already a total pro, you can scroll past this part straight to the list of scopes or use the quick navigation menu above.

This Guide is for Those Going the Distance!

Pricing: If you had to sell the boat to build this bad boy, you better consider selling the van to buy a scope for it. A scope should roughly match the quality of the firearm it will be married to.

After all, you don’t want them fighting one another, do you? This makes for a very expensive mistake, as the two will not be willing to work together and provide you with the performance you deserve.

If you’ve spent $1000 or more on your AR, you shouldn’t be looking for a cheap scope. If your AR15 is built like a Cadillac, the scope needs to be Cadillac quality as well! That doesn’t necessarily mean they should cost the same, but if you have a quality AR, do yourself a favor and buy a quality scope.

As a general rule of thumb, smaller tubes and objective lenses are usually cheaper. There are, of course, many variables that play into this so that doesn’t always hold true. Fixed focal lengths, or scopes that do not have a range of magnification are also usually on the cheaper side to their variable brethren.

Light: Some people think the larger the lens is (objective lens) facing forward the higher the magnification of the scope. This is usually not true and can be a tad misleading. This front facing lens determines how much light the scope can handle which will determine the brightness and quality of the sight picture.

With a small objective lens, targets in the woods and dimly light areas may not appear so vividly, causing you to skip over them unknowingly. If you’re always shooting in a well lit area, this probably won’t be much of an issue for you but if you plan to go hunting, chances are good that you may incur targets in shaded areas.

A second variable to light is the tube size. Tube size will also play an important role in light transmission so the same rules above apply here.

Remember, though, if your trekking with your rifle across the tundra, weight may be something you should consider. The larger tube and lens you have, the more glass you’ll be lugging with you. Glass is heavy, so don’t opt for larger if you won’t need it. Your muscles will thank you later for choosing the slimmest scope that gets the job done!

Effective Range: Shooting a mile sounds cool, and it is, if you have ammo that can actually reach that far. This guide is focused on AR-15s which fire either the .223 or 5.56 NATO rounds. This ammunition is not suitable for extremely long flights.

Their max effective range is roughly 500 meters for point targets and 600 meters for area targets. This means that buying scopes optimized for distances further than 600 meters is a terrible idea, both for your sanity and your bank account.

Most people will be using their AR-15s to take down targets within 400 meters or less. Make sure the scope you choose is suitable for this distance, or whatever distance your mission requires, so be it that the ammo can actually reach the missions specifications. If it can’t, you may want to look for an AR10 (effective to 1000 meters) or something a bit more powerful than an AR15.

Magnification: More magnification usually always sounds like a good thing, but if you’re using your rifle to hit moving targets or perhaps hunting, too much magnification may hinder your ability to acquire targets quickly and plan for incoming obstacles.

Higher magnification results in a much smaller window of sight but much further distances. If you’re perched on a shooting range, the high magnification is great as you have all the time in the world to find those targets and you know exactly where they’ll be.

Some high-end scopes will offer variable power, which means you can cycle through magnification levels. These may be especially handy for scouting out targets and then focusing more in depth once you have identified their location.

Something discussed in my red dot optics guide is the ability to use a 1x sight like an EOTech holographic sight paired with a prism magnifier to achieve the same results of a scope with the added ability of quickly switching and engaging close up targets with ease. Shooting 40 meters away with a 25x scope isn’t going to be enjoyable, but if you can switch between 1x and 30x with the flick of your wrist, you’ll have an unstoppable array of magnification at your fingertips!

Weight: We have already spoken about weight, but I’d like to put more emphasis on this factor. A scope may not seem like a huge contributing factor in weight, especially when holding it unattached to the rifle.

The problem is, all of these little additions add up on the rifle and vastly change the dynamics of the rifle itself. If you’re used to lightweight optics or simply using the attached iron sights, you will be thrown off by the added weight of a scope.

All of that glass will be weighing down on your rifle so make sure to practice with the added weight before deploying your new set up into action! A heavier weapon may also make it more difficult to hold steady or deploy in windy conditions.

These are all major factors at far distances, which are distances you’re aiming to achieve by attaching a scope in the first place, right?

Breaking Down What the Numbers Mean

If you start shopping before you completely understand all the fancy numbers with X’s in the middle of them, you’re going to be incredibly confused and will likely choose the wrong scope. What are all these X’s and MM’s?! I just want meters!

Example: 3-20 x 50mm

The first numbers are the power of magnification. In our example above, this means targets will appear 3 times larger than normal.

But wait, there are 2 numbers married together with a hyphen, what can that be? Those numbers indicate a range of power. This example shows us the scope is capable of a minimum magnification power of 3x all the way up to a maximum power of 20x.

Finally, the last number that is given in millimeters tells us the diameter of the objective lens. Remember, this will determine how much light will be transferred to your picture but will also result in heavier and harder to steady performance.

Reticles: An inexperienced scope shopper may not think much of the reticle coming with their scope, but you most certainly should consider these when spending your childs college funds or if you want the best shooting experience.

Types of Scope Reticles

Most reticles will vary and largely will depend on the user’s preference. The difference between a dot and a crosshair won’t change the performance of your rifle very much but one or the other may be more suitable for the condition of your eyes.

Some of these reticles even come with helpful tools to aid your journey on the path to professional marksmanship. These are called bullet drop compensator reticles (BDC). They include helpful little lines or dots set at multiple levels of range. Typically, you’ll dial in your center piece at the range you will most likely shoot at and then use the lines to adjust once you’ve found targets. These are best used in hunting or variable target situations where you won’t be privy to range information prior to engaging.

When you see Mil-dot you may think these sights are for military use, but the mil in mil-dot has nothing to do with the military. The Mil stands for milliradian (1/1000 radian) and the mil-dot will have little dots spaced out across your crosshairs that are precisely spaced apart. These offer the shooter advanced information using complex mathematical equations to form estimations of range.

Focus Adjustments: Most scopes will come with a focus adjustment dial or turret which is typically located near the ocular end of the scope, or where your eye is looking into the scope.

Scope Labeled with Basic Terminology
Example Scope with Parts Labeled

If can’t find it, your scope either doesn’t have one or you’re looking into the opposite end and you may need to retake your hunter’s safety course!

The focus adjustment is simply there to help you adjust the sights to be comfortable to you specifically. Everyone has different eyesight and thus you must finagle with the focus adjuster until it just feels silky smooth.

Some scopes, often foreign brands, will name a turret “focus” when it’s actually not the focus. I know, this is confusing and may throw you off, but be careful and don’t assume all “focus” labeled dials and turrets are actually for focusing. If they aren’t for focusing, they’re probably for Parallax.

Parallax: If you buy top end scopes, you probably won’t need to worry about this, but if you can’t fathom dumping all of your kids’ college funds and only part of them, you may need to consider if the scope suffers from the parallax effect.

In a nut shell, parallax is the change in sights depending on the angle of your eyeball. If you look at the crosshairs from different angles and the crosshair seems to move around and point to different things, this is parallax.

Parallax is very real and very dangerous as it will throw off the accuracy of your shot. If your scope has parallax (technically, all do, but many are so close to having no parallax that they claim they are parallax free) it might have an adjustment for this that you will simply need to play around with and practice until you get it right.

Eye Relief: (No More Making Up Excuses About How Someone Punched You In The Eye for Outshooting Them) Eye relief is how relieving it is after you shot down tomorrows dinner. Right? No? Eyes still not relieved? Hmmm.. okay. What about the ability to keep your dome piece further back from the sight while maintaining a clear sight picture? Is that relieving? Eye relief on a scope is measured by the distance your eye can positioned away from the edge of the ocular lens.

Some scopes require your eye to be as close as half an inch away from the lens, which is funny when the recoil slaps you in the face!

Other, (typically more expensive) scopes allow for several inches of eye relief. If a scope has more than 6 inches of eye relief it is usually marketed as long eye relief scope.

In short, further eye relief equals a more enjoyable shooting process, safer eyeballs, and less black eyes. No more making up stories about how someone punched you for outshooting them when you actually just got KO’d by your own rifle.

Fancy Bonus Features: Luckily, most furry critters haven’t implemented cutting edge technology to evade you and the same technology your grandpappy used to gun down these critters will still work perfectly fine today.

However, if you want the deer to tremble at the idea of being hunted by the terminator, check out these new age functions!

Illuminated Reticles: These are pretty self-explanatory and typically use batteries to light up your reticles. In low light situations these can really come in clutch, enabling the shooter to see his/her reticles clearly.

Range fingers: Some scopes come with lasers! No, the lasers wont fry holes through the hearts of your enemies, that’s what your 5.56 is for. However, it will display in depth range data for advanced shooters to calculate bullet drop or helping you choose which BDC line to use.

Heads Up Display: Some advanced scopes will include ballistics of the ammo you are using, windage, range, holdover points, parallax adjustments, and more to ensure the perfect shot each and every time. We are talking about tactical AR-15 scopes though and most of these scopes are for taking mile long shots. Some of these even have built in accelerometers that measure inclination and bullet rotation patterns.

Smartphone Buddies: Your smartphone does everything man, usher in the technology era! If you love using your smartphone for everything, you might find it interesting that there are scopes that can send data straight to your phone via Bluetooth. They can even send pictures and videos so people can watch you mercilessly slay those cute little demonic prairie dogs!

“Bro, I sniped an ant 3 miles away with my custom tactical AR-15”.

Now you can use the pics or it didn’t happen motto on guys like that!

Dialing in: So, you’ve bought yourself some fancy scope whose body is riddled with dials. Don’t be that guy who has no idea what the little clicky clickers do on his optics.

Let’s say you’re all sighted in and ready to go, by your standards. You hit the range and you’re constantly cursing, claiming your sights are RIGHT ON BRO but your grouping is two inches low and two inches to the right.

Instead of blaming the gun, resort to the clickers! (called turrets if you want to be firearm correct). Adjust your scope 2 MOA (minute of angle) to the left and 1 MOA upwards. This will adjust the scope to set the target on the dot (or reticle).

There is MUCH MUCH MUCH more that you can learn about scopes, but this guide should have gotten you up to speed on a basic level thus far.

Without further a due, I’d like to show you the best AR-15 scopes at multiple price points. Keep in mind, these are scopes that I personally like.

Which scope you choose may depend on how tacticool you think one looks over another or your personal preference on features. There are THOUSANDS of options, so consider the ones I’ll show you but also take a look around for other possible options you may enjoy.

This list is mostly for those of you who would rather hit the range now instead of later while shoppers are stuck behind their computer screens reading about every single scope on the market.

Budget Bin: AR-15 Scopes Under $100

Welcome to the Budget Bin. The scopes listed will not provide you with high performance.

We discussed earlier the quality of your scope should match your rifle. There are no AR15s for sale anywhere near $100 unless you robbed someone. These may be suitable if you just want a place holder or something to plink paper with for fun, but they will not offer a great level of accuracy, adjustability, or durability.

Also, when shopping in the Budget Bin, please make sure the scope can handle the recoil of the firearm you are placing it on. Not all scopes are built to withstand force, which is exactly what they receive when put on powerful rifles. Just consider recoil, especially if you are looking to use this scope on another rifle build down the road.

1. CenterPoint MSR with Picatinny Mount

Cheap AR-15 Scope

Price Range: Under $75
Magnification: 1-4x 20mm

My review: This optic is perfect for those that shoot their AR-15s a few times a year just for the pure enjoyment of firing their weapons. It won’t offer supreme marksmanship accuracy, but it will get the job done.

The construction is mostly plastic which makes the durability of this scope pretty low. I recommend using Loctite or glue on the mounting screws as they become loose with just a few shots resulting in losing your zero. So long as it doesn’t rattle loose and move around, this scope isn’t horrible, it’s just not great.

Functions and Features:

  • 1” tube diameter
  • Quick aim reticle with 3 MOA center dot
  • Versatile ring 65 MOA
  • Ideal for 250 yards
  • Decent amount of eye relief
  • Includes picatinny rail mounting rings and lens covers

The only cons I see:

  • Sight picture is hard to attain at low power intervals
  • Very difficult to adjust the turrets as they are stiff and also plastic, making them easy to break

Key Features:

  • A cheap scope that will hold up to the recoil of an AR15 and even a 300 blackout
  • Incredibly cheap option for under 250 yards

2. UTG BugBuster CQB

AR-15 Scope Under $100

Price Range: Under $100
Magnification: 3-9x 32mm

My review: This scope isn’t specifically designed for AR-15s, but it will work just fine. Being under $100 gives this scope a pretty big advantage over its direct competitors. This is the very popular scope for AR-15s here in the Bargain Bin.

This scope has an intuitive mil-dot reticle with multiple color options. It seems to be very durable considering it’s a cheap scope, although it is certainly not waterproof and I’d be weary of being caught in the rain, even though it does say it’s rainproof. This is a good scope if just want to have a little enhanced range capability at the shooting range. I wouldn’t take this out on a multi-day hunting trip or expect to land accurate groupings over 300m with it.

I attached a video review of this scope below. This scope and the UTG BugBuster listed above are both great for the money. I recommend choosing the scope that best fits your intended use.

Functions and Features:

  • 1” tube
  • Emerald coated for high light transmission
  • Lockable turrets and zero resettable
  • ¼ MOA per click adjustments
  • Range estimating mil-dot reticle
  • Red or green illumination options
  • 2” sunshare
  • Flip open lens caps
  • Totally sealed and nitrogen filled tube
  • Shockproof, fog proof, and rain proof

The only con I see:

  • Not completely waterproof

Key Features:

  • For under $100, this scope offers a pretty good mil-dot reticle
  • This scope seems to offer an okay level of durability being shockproof and rainproof

3. Bushnell Banner Scope (Best Under $100)

Bushnell Banner Dusk Scope

Price Range: Under $100

My review: This is a fantastic beginner scope that delivers hints of performance you’d find in upper tier scopes. This is the highest rated scope in the bargain bin. This scope is advertised as being a great scope in low light settings, although you can use it in direct sunlight as well. Unfortunately, Bushnell doesn’t include or even manufacture a sun shade compatible with this scope and the scope has a bit of distortion at its highest levels of magnification. Aside from those two minor issues, this is a fantastic scope for an AR-15 or smaller calibers. It’s waterproof and feels surprisingly tough for its price!

If you want to learn more about this scope, I attached a video review below. I recommend skipping to around 4:24. You can see the distortion at higher magnification levels. Overall, this is a great scope for the money! You can’t go wrong with this scope or the one listed above.

Functions and Features:

  • 3.3” eye relief
  • 3-9x 40MM
  • Low light capable for use during dusk and dawn
  • DDB multicoated lenses
  • Multi-X reticle with ¼ MOA
  • Windage and elevation turrets
  • One piece tube design filled with nitrogen
  • Waterproof
  • Fog proof
  • Shock proof

The only cons I see:

  • Struggles in direct sunlight due to lack of a sun shade
  • Distortion on high magnification levels

Key Features:

  • One of the best budget scopes for low light operation
  • Holds zero surprisingly well for being so cheap

Rookie Numbers: AR-15 Scopes Under $200

At under 200 we are still talking rookie numbers. These are scopes that you can most certainly use to hunt and play around with. You won’t find fancy functions or extreme durability but you will find decent optical solutions for cheaper than most AR-15s will cost (which is against the rules of MarineApproved).

If shooting casually for pure enjoyment is your thing, these sights will be enough to suffice. If you are looking to take long pot shots accurately, keep scrolling.

4. Vortex Optics Crossfire II

Vortex Optics Crossfire II

Price Range: Under $175
Magnification: 4-12x 40mm

My review: This is one of my favorite optics in the under $200 category, but it’s still not as good of a value as the Vortex or Buckermasters 2 listed below. This scope doesn’t have any spectacular functions, but it does have a handy little BDC reticle and the most basic adjustments you’d need to have a little fun at the range. It is completely sealed and probably okay for a little rain during a hunting trip. With this scope you should have no problem using the medium range of your AR-15 consistently. This is one of the top rated scopes out there and definitely worth taking a good look at.

Functions and Features:

  • There are several versions of this scope allowing you to find the features and functions right for you
  • Long eye relief and forgiving eye box
  • Multi-coated lenses
  • Fast focus eye piece
  • Capped reset turret
  • Single piece tube construction at 1”
  • O-ring sealed and nitrogen filled
  • Waterproof and fogproof
  • Popular scope for coyote hunting
  • Dead-hold BDC reticle

The only potential cons I see:

  • Parallax adjustment turret is difficult to use

Key Features:

  • Very high-quality glass for a cheap price
  • BDC reticle

5. Athlon Optics Talos Rifle Scope

Athlon Optics Talos Rifle Optic

Price Range: Under $200
Magnification: 6-24x 50mm

My review: This is a pretty great little scope to have for medium ranges. It has no incredibly amazing features but it is relatively durable and will provide good consistency in the 100-200 yard range. This is the lowest scope on the Talos line, which is known for their high-end scopes but this scope performs just as good at a lower price if you are shooting for fun.

Functions and Features:

  • Multi-coated lenses for optimum light transmission
  • True color brightness
  • Etched reticle
  • Heat treated one piece tube
  • Nitrogen purged and completely sealed
  • Aircraft grade aluminum tube
  • 3” eye relief
  • 23oz weight
  • Mil reticle

Key Features:

  • High durability compared to others in this price range
  • Crystal clear image with no shadowing even at highest magnification settings

6. Nikon Buckmasters II BDC Rifle Scope

A Good Hunting Scope for AR-15

Price Range: $155
Magnification: 4-12x 40mm/
Note: Best Value Under $200 (2nd Overall)

My review: As far as overall performance and quality, I feel it is second only to the next scope on this list (by a very small margin). That said, this scope is around $15 dollars less than the next scope, so I would actually say this is the best AR-15 scope for the money in the under $200 category. So long as you get one that isn’t broke, isn’t a knockoff, and doesn’t come with factory defects, these scopes are incredible for the price. I would almost say they are equal in usability and precision as scopes in the next price range. It has a decent amount of durability and really does offer a great sight picture at every magnification level. I attached a video so you can learn more about the scope and see what the BDC reticle looks like below.

Functions and Features:

  • Nikon Patented BDC Reticle
  • Multicoated lenses for high resolution sight picture and maximum brightness
  • Waterproof, fogproof and shockproof
  • Parallax adjustments
  • Nitrogen purged and O-ring sealed design
  • 3.7” eye relief
  • 1” tube diameter
  • Spot on Ballistic Match Technology and mobile device application

The only cons I see:

  • Nikon has had a lot of reported issues with low quality control
  • Difficult to contact Nikon customer support

Key Features:

  • Crystal clear sight picture on any magnification setting
  • Patented BDC reticle offers easy to view bullet drop compensation

7. Vortex DiamondBack (Best Under $200)

Vortex Optics Diamondback Scope

Price Range: Under $200

My review: This is a fantastic budget option for hunting and medium range target practice. Firstly, you’ll notice very easy to see crosshairs with enough eye relief to be comfortable when using for long durations. The XR crystal multi-coated lenses provide tons of light transfer, even late in the day as the sun is setting.

There are multiple different variations of this scope and the primary difference is the magnification. I chose to review the 3-9x40mm because I feel as though this is the best option of the six for an AR15 setup. Some of them are a bit overkill for a 5.56 round but you could also use the 1.75-5×32, 3.5-10x50mm, and the 3-9x40mm. This is my choice as the overall best scope for AR-15 rifles in the the under $200 category.

I will attach a YouTube video below so you can learn more about this scope.

Functions and Features:

  • 3-9x40mm
  • Head-hold BDC reticle
  • Steel precision turrets
  • One-piece tube design that is purged by Argon and O-ring sealed
  • Hard anodized finish
  • Crystal multicoated lenses
  • Shockproof
  • Water proof
  • Fog proof

The only con:

  • No lens caps

Key Features:

  • Good light capture even in dawn settings
  • Incredibly durable

Enthusiast: AR-15 Scopes Under $300

If you’re looking for getting the most bang for your buck, there are some pretty good scopes in this price range.

8. Nikon P-223 BDC 600

Nikon 223 Rifle Scope

Price Range: Under $300

My review: This scope is specifically designed for an AR-15 shooting a .223 Rem/5.56 NATO round and has a BDC reticle inclusive of hash marks that are optimized for the round itself. I was very surprised when I first saw this scope. At first glance, it doesn’t look like anything special, but once you’re glaring down the scope and nailing targets with ease at variable ranges, you’ll see why this is a top-rated scope! They also make these with higher levels of magnification and for other rifles such as a .308 and AAC 300 BLK. Overall, I would say this is the best AR-15 scope under $300, but the Leupold scope below is a very close second.

I attached a good video review I found on this optic below. Keep in mind they are reviewing the 3-9x40mm version, but the overall features are the same.

Functions and Features:

  • Polymer and aluminum construction
  • Proprietary Nikon lens multi-coating
  • Spring loaded instant zero rest turrets
  • BDC 600 reticle with open circle aiming and hash marks 100 yards to 600 yards
  • Spot On Ballistic Match Technology
  • Quick focus eye piece
  • 1” tube diameter
  • 3.7” eye relief
  • Waterproof
  • Shock Proof
  • Fog Proof

Key Features:

  • Bullet ballistic match technology is great for squeezing out the most effectiveness you possibly can
  • The scope is surprisingly durable

9. Primary Arms SFP Riflescope with ACSS Reticle (Best Under $300)

Primary Arms Scope for AR-15

Price Range: Under $300

My review: The first thing people want to know is how well this performs against its more prestigious (and expensive) Trijicon RS24. That scope is also on our list and I will say, the Trijicon scope is most certainly better. If you have the money, go ahead and step up to it. However, if you don’t have a huge budget and you’re looking for something almost as good, the Primary Arms SFP comes up HUGE! At only half the price of the RS24, you get enhanced magnification, worse quality glass (but still great), and similar construction and styling. Realistically, this is one of the best scopes I’ve ever reviewed that I’d still consider cheap. At under $300, this scope offers a lot of what the $500+ scopes offer. If you don’t mind a slightly less than perfect glass quality, this scope should end up near the top of your wish list.

Notable Features:

  • 1-6x24mm
  • Second focal plane
  • Patented ACSS BDC AR15 etched reticle (5.56, 5.45, .308)
  • 11 brightness configurations
  • IP67 waterproof
  • Nitrogen purged tube
  • Multi-coated anti-reflective lenses
  • 6063 aluminum construction
  • Lifetime warranty

The only cons I see:

  • Awful eye relief at maximum magnification
  • Halo effect on low magnification

Key Features:

  • Two eye capability on 1x and great eye relief with low magnification
  • Just as versatile as the Trijicon RS24 for roughly half the price

10. Leupold VX-Freedom

Leupold VX Freedom Scope

Price Range: Under $300

My review: This scope is everything you need and nothing you don’t. As far as value, it’s an absolute steal. It doesn’t have the fanciest design or extra features but at under $250 it’s a fairly high-quality optic. The crosshairs are especially thick, good for those with less than perfect eye sight. This scope also has more than enough magnification for the AR-15 and is very easy to adjust with precise finger clicks on its metal turrets.

Functions and Features:

  • 3-9x40mm
  • 6061-T6 aircraft aluminum construction
  • One inch main tube
  • Waterproof
  • Fog proof
  • Twilight light management system
  • 1/4 MOA precision clickers
  • Roughly 4” of eye relief

The only bad thing:

  • No lens caps

Key Features:

  • Feels incredibly sturdy
  • Does well during low light situations such as dawn and dusk

Tried and True: AR-15 Scopes Under $500

For the most part, AR-15’s are sold around the $500 mark. This means scopes in this price range will be suitable for marriage for many AR-15s.

11. Vortex Optics Viper 6.5-20x50

Vortex Optics 223 Scope

Price Range: Under $500

My review: One of the craziest adjustable magnification scopes I’ve gotten to review, the Vortex Viper did not disappoint. You could, if you wanted, smash targets at 100m and then seconds later land shots consistently at 1000m (rifle defendant). Of course, for applications regarding AR15s, that’s probably a bit overkill and you’ll most likely be using its lower levels of magnification.

Vortex always amazes me. The brand comes off as a sort of budget brand to me for some odd reason, however, each and every time I review one of their products I am impressed! The sight picture is bright and clear and the durability of this scope is hardly any less than our top dollar mil-spec scopes.

Here is a pretty good video review on this scope. I recommend skipping to around 1:35 in the video.

Vortex BTC Reticle

A lot of you may argue with me on this, but Vortex time and time again proves that it is one of the best value brands in the optics game. They certainly aren’t the cheapest, but these scopes are worth saving up for.

Functions Features:

  • 6.5-20x50mm
  • 30mm main tube with hard anodized finish
  • Second focal plane
  • Mil-dot MOA or dead-hold BDC reticle options (different scopes)
  • Argon purged tube
  • Capped reset turrets for quick indexing

Key Features:

  • Vortex lifetime warranty
  • Glass quality that rivals high-end scopes

12. Leupold VX-R Patrol

Leupold Illuminated Rifle Scope with Motion Sensor

Price Range: $500
Magnification: 1.25-4x 20mm

My review: Leupold is probably one of the most well-known high-quality scope makers out there and each and every one of their sights lives up to it’s name. This sight is incredibly easy to use and fits very well on top of the AR-15. It doesn’t have intense magnification levels, but with an AR-15 you don’t really need further magnification than what this scope offers. The price is a little high compared so scopes of this same magnitude but you’re probably paying a bit for the name. If that doesn’t bother you, pick this one up!

Functions and Features:

  • Constructed of 6061-T6 aircraft quality aluminum
  • 3:1 zoom ratio
  • Waterproof and fogproof
  • Twilight light management system
  • Leupold proprietary hashmark FireDot reticle with 10 MIL centralized dot
  • Windage and elevation adjustments
  • Diamond coating on exterior lenses gives abrasion resistance and ultra-light transmission
  • Motion sensors that turn off the reticle when not in use and turn on the reticle when the scope senses movement

The only cons I see:

  • Exposed knobs are easy to knock out of place
  • Reticle is a little on the thick side, taking up more of the sight picture than I would want. This is really just a personal pet peeve, though.

Key Features:

  • Legendary Leupold quality with their patented hashmark FireDot reticle
  • Low weight design compared to similar scopes

13. Burris 200437 MTAC

Burris AR-15 Optic

Price Range: Under $400
Magnification: 1-4x 24mm

My review: This scope is probably one of the highest quality scopes you can purchase for an AR-15 that is suitable for short to medium distances. This scope obviously isn’t made for long distance shots so I wouldn’t expect it to fair well there, but it does offer incredible sight picture and unbeatable eye relief.

This sight also has a very elegant design that I don’t normally mention, but this one is just impressive that I couldn’t help it. The Burris MTAC is a fantastic low to medium range scope that is well priced and sits beautifully on top of any AR-15 platform. It’s also very lightweight compared to its near competitors and comes with a lifetime warranty.

Functions and Features:

  • Lifetime warranty
  • High quality aircraft grade aluminum construction
  • 30mm Tube diameter
  • 17 ounce weight
  • 10 brightness intensity settings
  • Ballistic QC illuminated reticle
  • LPT knobs
  • Flip lens covers

Potential cons:

  • Reticle is a bit overkill and a little distracting
  • This scope is only made for short to medium distance targets and does not perform well in long distance, as it’s not designed to

Key Features:

  • Life time warranty that you probably wont ever need to use due to high durability
  • Incredible eye relief for a scope of this design

What Do You Do for a Living?: Scope for AR-15 ($500 and Up)

Welcome to the buy once cry once section. In this section I detail random scopes that I like above $500. Most of these are probably a bit unnecessary to the casual AR-15 enthusiasts but may be a life saver to a competitive shooter or die hard hunter. If you are truly looking for the best scope for AR-15 rifles regardless of price, this is is where you should be looking.

14. Vortex Optics Viper PST Gen II

Vortex Viper Generation two 223 Scope

Price Range: Around $500

My review: Firstly, this scope comes in multiple different magnifications. I recommend the 1-6x VMR 2 MOA for the AR-15.

Secondly, this is the budget version of a top of the line scope, the Razor HD. Basically, it has slightly lower tiered glass and a few corners were cut to reduce the price. With this said, however, don’t count this scope out! It’s amazing and its certainly usable for any mid to long range AR-15 set ups. Comparing the Razor HD and the PST physically side by side is the only way you’ll actually notice a quality difference. The PST is just slightly bulkier and has slightly less lens clarity, but for the money you’re saving, I would say it’s most certainly worth it!

Functions and Features:

  • 1-6x24mm VMR
  • 2 MOA
  • 3.8” eye relief
  • Windage and elevation adjustments
  • Second focal plane rifle scope
  • Laser etched turrets
  • Intuitive hash mark Vortex Reticle with detailed holding points and 10 intensity levels
  • Extra-low dispersion glass
  • Multicoated XR lenses with Armortek coating for added lens protection
  • O-ring sealed Argon purged aircraft aluminum tube
  • Adjustable parallax and RZR zero stop

The only potential con

  • Glare on the lens when sun is behind the shooter

Key Features:

  • Much cheaper version of the coveted Razor HD but almost just as good
  • No nonsense lifetime warranty

15. Trijicon RS24 AccuPower

Shooter Holding Rifle with AR-15 Scope Attached

Price Range: $615

My review: Of course, anything from Trijicon is going to cost big, but do they come up big when you need them? In the case of the RS24, that answer is absolutely yes! This is one of the most complete all-around scopes I’ve ever encountered and to be honest, seeing the price tag of a quality Trijicon under a thousand bucks was a beautiful sight all of its own. For starters, this thing is built tough! You can really tell that Trijicon upholds its ruggedness no matter if its an ACOG, red dot, magnified optic, etc. Always expect battlefield level durability.

Secondly, the glass is incredibly clear but under direct sunlight I feel like the illumination could be a little brighter. Aside from this one slight drawback, the optic performs great. I love the fact that you can be shooting with two eyes open with the red dot at 1x and with a quick click engage targets accurately at 400m. This is the closest high-quality scope to a multi-tool you’ll find!

Functions and Features:

  • 1-4x24mm
  • 24mm Objective lens
  • 30mm tube diameter
  • Second focal plane
  • Waterproof up to 10 meters
  • Made of 6061-T6 anodized material
  • 31-hour battery life
  • The scope can be purchased in several different reticle types and color configurations

Key Features:

  • Top class versatility
  • Battlefield grade durability

16. Leupold VX-5HD

Leupold 0603 2228 High End Scope

Price Range: $600-800

My review: This scope is probably not for the everyday range queen but more so for those of you looking to complete that dream build with an epic scope atop. The Leupold VX-5HD contains the highest quality glass of any variable magnification scope I’ve reviewed and despite it having a rather small objective lens, it delivers incredible brightness, even in low light situations. This scope isn’t going to blow away the competition, instead, it simply one-ups just about everything on this list and the price surely reflects that. In scopes like this, slight increments in glass quality cost huge amounts of money! Oh yeah, it’s also tough as nails with lens coating that you can drag through the dirt and waterproofing that you can submerge up to 10 meters.

Not bad Leupold, not bad at all. Just a tad expensive!

Functions and Features:

  • 1-5×24
  • 30mm tube diameter
  • Duplex reticle
  • 6061-T6 aircraft aluminum construction
  • Proprietary argon and krypton purged tube
  • Guard Ion lens coating
  • Leupolds custom dial system, the ZeroLock 2
  • Twin Bias Spring Erector system
  • Ultra-bright sight picture
  • Lifetime warranty

The only cons I see:

  • A lot more expensive for just a little bit more

Key Features:

  • Ultra-light for a scope this size (13.4oz)
  • Incredible sight picture quality

17. Vortex Optics Razor HD Gen 2

Vortex Optics Razor HD Gen II Rifescope

Price Range: $1100

My review: I talked earlier about how Vortex always seems like a budget brand but then blows my socks off.

Well, I’ve finally found their flagship model and yes, socks have been blown once again! The first thing you’ll notice is how sleek the casing really is. Holding this thing you’ll know someone (or you) shelled out serious cash because they (or you) enjoy the finer things in life! For lack of a better explanation, this scope is like the caviar version of the Vortex Viper. The HD Gen II glass is breathtaking, its almost as if the glass doesn’t even exist. Even at its highest magnification, sight picture remains crystal clear and bright as ever.

The scope itself is rock solid, durable enough to drag through dirt and mud and still have a brand new looking and functioning scope. The scope also comes in 3 different models, with the reticles being the only difference. Of course, since this is an AR-15 scopes page, I’d like to recommend the Jm-1 BDC MOA version as that model is optimized for the AR15 specifically.

Functions and Features:

  • 1-6x24mm
  • 30mm tube size
  • O-ring sealed argon purged tube
  • VMR-2 MOA Reticle with illuminated center dot
  • APO optical system via extra-low dispersion glass
  • Multi-coated XR Plus anti-reflective coatings
  • Armortek anti-scratch coatings
  • Illumination dial with 11 brightness settings with off positions between each setting
  • Single piece aircraft aluminum construction
  • Water and fog proofing

The only con I see:

  • The only con is that this scope will likely cost more than most peoples AR15 builds. Buy once cry once!

Key Features:

  • HD Gen II glass is in a category of elite optical glassware
  • The off setting between each brightness click is incredibly intuitive

18. Trijicon ACOG TA31 ACSS

Trijicon ACOG Scope with Red Reticle

Price Range: Around $1250
Magnification: 4×32

My review: It’s a Trijicon ACOG. Do I need to say more? This is one of the most legendary sights on the market today. It’s nearly the exact optic I was issued for my M4 in Corps. It is battle tested and ready to roll with an innovative buy once cry once price and quality!

Yes, it will likely destroy your bank account, but if you’re shooting well who cares? Your AR15 has an ACOG!

This thing is meant for rapid deployment and tight groupings at medium range. You won’t be sniping things a mile away, but you will get an incredible tactical AR-15 scope with an almost indestructible design. Buy this and never shop for a mid-range scope again.

The video below does a good job explaining how to use the BDC on the ACOG.

Functions and Features:

  • Fixed 4x magnification
  • Dual illuminated reticles. ACSS 5.556 in green
  • Second focal plane optic
  • Waterproof and shockproof
  • Trijicon proprietary BDC reticle

Pros

  • Specifically designed for AR-15 style rifles and calibers
  • Legendary ACOG design offers an incredible sight picture

Cons

  • Your wife might divorce you for spending such a ridiculous amount to see stuff.

Key Features:

  • Specifically designed for AR-15 style rifles and calibers
  • Legendary ACOG design offers an incredible sight picture

19. EOTech HHS ll ExpS2-2 with G33 3x magnifier

EOTech 3x Magnifier Optic

Click edit button to change this text. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

Price Range: Under $1000
Magnification: 1x or 3x

My review: I’ve actually reviewed this setup already in my red dot optics guide but since I like it so much, why not talk about it here, again? I think it’s fitting if you have the moolah to shell out for it!

With this EOTech system you’ll be getting the best of both worlds. A legendary 1x holographic sight with a 3x prism magnifier that sits on a hinge. Easily flip between the two and engage with targets in both close and medium range.

This is most suitable for competition shooters or combat deployments but if you so choose, you can certainly use it to hunt and/or impress people at the range. Spend some money and have some fun, this thing is awesome! Just beware of knock offs, they’re everywhere. Ensure you’re really buying it from EOTech.

Functions and Features:

  • Holographic hybrid system
  • 65 MOA circle with 2 1 MOA aiming dots
  • Single transverse 123 battery to reduce sight length
  • Takes up only 2.75” of rail space
  • Locking quick detach lever
  • Quick switch to side (STS) mount for magnifier

Capable of handling up to 550lb, either a single or double nest, and both spreader and non-spreader bar hammocks, this stand was specially built for relaxing with family or a loved one outdoors.

Key Features:

  • Quickly cycle between 1x or 3x optics with a holographic and magnifier system
  • Used by the US Special Operations

20. Sig Sauer SOT61008 Tango6

Sig Sauer AR-15 Scope with 3 Gun Reticle

Price Range: Around $1400
Magnification: 1-6x 24mm

My review: If you have the money, this scope is incredible. It’s durable and heavy, built like a bulldozer and just as strong as one. Using this scope will give you the freedom of close up engagements on 1x with both eyes as well as intense 6x magnification for medium to long range targeting. It’s really just another Sig product, need I say more? Yes, they’re pricey, but they are also of the highest quality in any category they release products in, scopes being no different.

Functions and Features:

  • 3 gun reticle 0.5 MOA adjustment
  • 107ft of view at 100 yards
  • 3.8” eye relief
  • Night vision compatible
  • 11 brightness settings
  • Sig Sauer Hex optical system
  • Hellfire Fiber optic and glass etched illuminated reticles for first or second focal planes
  • Lock down zero system turrets with zero stop and reset
  • Shoot with both eyes open on 1x

Key Features:

  • Using 1x is just as good as having an exposed reflex and using 6x is just as good as having a full-blown scope. It’s the best of both worlds!
  • Extremely precise MOA adjustments
