Best AR 15 Scope

Mounting your AR 15 with a scope is as personal and customizable as building the rifle itself.

But, once you're ready to add an optic to your AR, you'll find the market awash with scopes with drastically different prices, build quality, and features.

How much should you spend?  Is there a one-size-fits-all scope?  How do you choose between a scope or a sight for an AR 15/MSR rifle?

What is the best scope for an AR-10?

We'll discuss these considerations and offer up our scope recommendations.  Let us help you complete your AR platform armed with as much information as possible.

While the wide-ranging lineup of scopes below is by no means a comprehensive list, we've provided some of the best scopes that have been rated and tested by AR owners just like yourself.

However, if you are looking for something that fits a specific budget or hunting activity, be sure to also check out some of the other lists (below) we have compiled to find the AR-15 scope perfect for your needs:

To start with, we're letting you know from the get-go that we will use the terms AR 15 (ArmaLite AR-15) and MSR (Modern Sporting Rifle) interchangeably throughout this post.

If you've been building your AR 15 from scratch, you'll appreciate the diversity of the optics market when it comes time to mount your newly-built rifle with a scope.  The thing about MSRs?  They're extremely modular and customizable to perform for your needed application.  So, what is it you're looking to do?

Uses for An AR-15 Optic:

  • Plinking/Recreational shooting
  • Target shooting
  • Small-game, Varmint, Predator, and Big-game hunting
  • 3-Gun, Competition shooting
  • Tactical, Military, Law Enforcement use
  • CBQ to mid-range shooting
  • Home defense, Surveillance, Security use
  • Night vision, night hunting, night surveillance use

The intended use for your MSR will guide your scope requirements from scope dimensions, build quality, and budget to reticle style, magnification, and added features.  As you can see, there is no one-size-fits-all scope for your rifle.

But, what about the red dot versus scope debate?

Red dots are fast and are excellent for CQB (close quarter battle) needs.  At the same time, a low powered 1-4x, 1-6x, or 1-8x scope on an AR 15, especially one with an illuminated reticle or center dot, can certainly offer the same advantages, plus some, to provide versatility to your MSR system.

We may tend to be biased towards low power variable (LPV) scopes, but they also come with tradeoffs to red dots.  Apples and oranges?  Leaving this discussion for another day, remember to be application-specific for your needs.

Since we can't read your mind or presume to know what you're up to, we'll just lay out the lineup and you can choose what scope or sight speaks to you.

Best AR-15 Scope Reviews

1. Trijicon VCOG 1-6X24 - Best Overall

Trijicon VCOG 1-6x24
Image Credit: Trijicon

Trijicon brings the highly praised reliability of the ACOG to the table and combines it with variable power to give birth to the VCOG – the Variable Combat Optical Gunsight. Demanding the absolute best in performance and quality for an AR15 will require the most generous budget you can come up with.

Pros:

  • Trijicon quality
  • Excellent glass clarity
  • FFP reticle
  • Illuminated reticle
  • 4” eye relief

Cons:

  • Price

Trijicon scopes are known for their close to indestructible build quality. Having been made from forged aluminum alloy, it’s tough, strong, and ready to withstand the abuse from hunting, duty, and patrol applications.

It’s a LPVO scope with 1-6x magnification for close to mid-range use. Of course, with 90 MOA of travel, the opportunity is there to reach out for long-range shots if sniper applications are required. However, it’s highlight feature is the 1x power for CQB performance with reticles in the first focal plane with illumination. The integrated dial fin makes things easy to shift between power ranges for extended seeing or back to 1x use.

There are multiple reticle options each with their own product number as they range from .22 specific reticles to .223/.556 options and .308/7.62 calibrations and then different designs with horseshoe dots and crosshairs. Trust Trijicon to provide a reticle that will suit your needs. Each reticle model also comes with either a TA51 or quick release mount.

With a AA battery as the power source, it runs up to 700 hours when on brightness level 4. It fulfills the modern expectation of having intermittent ‘off’ positions between brightness settings.

As everyone knows, Trijicon is an expensive brand, but quality tends to match its price point. Having the best on your AR will require a generous budget.

2. Vortex Razor HD Gen II-E 1-6X24 - Best Illuminated Reticle

Vortex Razor HD Gen II-E 1-6×24
Image Credit: Vortex

It's only fitting that a high-end Vortex make the list.  The Razor HD Gen II-E rifle scope is perfect for the AR/MSR platform.

What does the "E" stand for?  "Enhanced."

This scope represents the new and improved Razor HD Gen II series, and you're about to see why it has become a fast favorite.

Pros:

  • Excellent glass quality
  • 30 mm tube
  • SFP/illuminated reticle
  • Wide adjustment travel
  • Wide diameter turrets

Cons:

  • Price

This scope has the favorite LPV magnification range of 1-6x to replace your red dot and magnifier on your MSR or carbine.  It sheds the weight of its predecessor weighing in at only 21.5 oz.

With a 30 mm, single-piece tube body, it's robust and allows for a colossal 150 MOA adjustment travel for both windage and elevation.  50 MOA revolutions and zero-resettable, wide diameter turrets allow for streamlined performance in any situation.

With an SFP (second focal plane) reticle, the crosshairs won't change size on you regardless of magnification.  Use the reticle to hold over out to 600 yards.

The BDC reticle has a center illuminated dot to help acquire fast target acquisition and draw the eye to the center.  Lock in that brightness setting with the locking illumination feature.

Stay low and close for CQB with 1x power and crank it up to extend your observation range when out in the field or hunt.  Glass quality is superb as the Gen II-E scope has it all from an APO system to Optically Indexed Lenses, HD Lens elements, and more.

Although it's still expensive for most shoppers hunting for an affordable scope, the Gen II-E 1-6x is unparalleled in its price range.

If there's a scope you won't have buyer's remorse with, it's this one.

3. Trijicon ACOG 4X32 TA31F - Best Red Dot Combo

Trijicon ACOG 4X32 BAC
Image Credit: Trijicon

There's no way we could pass up the chance to feature a tried and true AR 15 sight, the ACOG.  The Advanced Combat Optical Gunsight has been a U.S. military staple for more than a decade.

What does this fixed magnification sight offer the shooter that puts it up at the top with best AR-15 red dot sights?

Pros:

  • Combat proven
  • Battery-free illumination
  • BDC/ranging reticle
  • Trijicon quality
  • Use with both eyes open

Cons:

  • Price

Anything over $1000 is going to be seen as an expensive buy, but Trijicon is one of those brands where you get what you pay for - quality.  Durability has never been an issue for the well-known brand or its loyal buyers.

While the reticle doesn’t have the traditional red dot, the chevron pattern is still illuminated and is specifically designed for .223 (5.56) caliber rifles.  Crosshair hash marks allow for bullet drop holdovers out to 800 meters, and you can also estimate range with silhouette targets.

With fixed 4x power, it now has magnification and an illuminated reticle that makes it one of the best red dot sight combos around.

You don't have to worry about batteries or LEDs failing you when you need it most.  Reticle illumination in the ACOG is powered by fiber optics for daylight use and tritium for low light/nighttime use.

You can also use the sight with both eyes open thanks to the Bindon Aiming Concept that allows for quick CQB use.  However, you'll have to get around the unforgiving 1.5" of eye relief which will greatly limit your field of view.

The ACOG 4x scope has been a long-time favorite, and the TA31F model has features made specifically for the AR 15 gun owner.

As a tactical gunsight that was designed for military use, it sure lives up to its reputation for the civilian market.

4. EOTech Vudu 1-6x24 FFP – Best High-End LPVO

EOTech Vudu 1-6x24 FFP
Image Credit - EOTech

In a market where LPVOs are popular for the tactical carbine, the 1-6x reigns king with its CQB 1x magnification. Covered by the NoBS Warranty, you won’t need proof of purchase, and it’s fully transferable. That’s a warranty you can get behind considering the cost of a Vudu riflescope.

Pros:

  • EOTech tough
  • XC high-density optics
  • CR2032 battery
  • Multiple reticle options
  • Made in Japan

Cons:

  • No locking turrets

The Vudu has exposed turrets sitting on a 30mm tube that provides 29 mrad in elevation travel and 23 mrad in windage. Turrets adjust in .2 mrad increments. While extremely tactile and the scope tracks true, it is a bit of a disappointment that they are not locking at this price point. This should be noted by those on patrol and hunters too.

With 1-6x magnification, it has decent eye relief of 3.94-3.23” and can be used effectively with both AR15 and AR10 calibers. The Vudu has FFP reticles that are made for speed and are easy to see. They’re quite simple in design with minimalist markings for drop.

They are all glass-etched, visible without illumination, and they feature EOTech’s speed ring, but they differ at the center. The SR1 is a ranging mrad reticle that is non-caliber specific. The SR2 has BDC drop calibrated for the 7.62 round whereas the SR3 is calibrated for the 5.56 round.

The scopes are O-ring sealed for water resistance, nitrogen-purged for fogproof protection, and are made in Japan. The optics are made with XC high-density, low dispersion glass with coatings to provide stunning clarity and resolution.

Powering illumination with a CR2032 coin-cell battery, it’s a lightweight power source that doesn’t add to the already hefty 20.1oz weight. In context, it’s not any heavier than alternative LPVOs as they are generally inherently heavy.

The Vudu marries magnification, true 1x both-eyes-open performance, red dot tech, and an FFP reticle into a scope and does it skillfully with EOTech style.

5. Trijicon AccuPoint 1-4X24 TR24R - Best for Hunting

Trijicon TR24R AccuPoint 1-24x24
Image Credit: Trijicon

The AccuPoint may just be the ideal combo of a red dot and magnified optic in one.  Who will benefit from one?  A big game hunter, someone who appreciates affordability, or a shooter who needs fast acquisition in difficult terrain or environments.  Does this sound like you?

Pros:

  • Price
  • Battery-free illumination
  • Glass-etched reticle
  • Low magnification
  • 90 MOA adjustment travel

Cons:

  • Close-mid range only

The Triangle Post reticle is simple, fast, and easy to use.  If you're looking for sniper accuracy at extended ranges or for bullet drop compensating crosshairs, this isn't the reticle model for you.  But, what will the triangle post reticle do for you?  It gets you on target fast.

If you're looking to stay within your comfort zone of using a daylight illuminated reticle while moving away from red sights into LPV scopes, this AccuPoint does it.

You don't have to muck around with batteries or worry about illumination features failing you.   The red triangle aiming point is powered by fiber optics and tritium for battery-free, illuminated benefits - no more worrying about battery life!

As you can guess, for a Trijicon scope under $1000, it's a star favorite.  It has Trijicon build quality behind it, a glass-etched reticle, 30 mm tube, and it's completely weatherproof.

With 90 MOA of adjustment travel, you can dial out to extended ranges if you're in the mood to test your skill.  But, as a 1-4x scope with a simple reticle, your best usage is going to be within close to mid-range distances that's great for many types of hunting, target shooting, and CQB scenarios.

What else makes it an excellent scope for these applications?  It's super lightweight at only 14.4 oz.  Why tack on weight, extra magnification, and added cost when you can take down deer, bad guys, and ping steel with the AccuPoint?

6. Steiner P4Xi 1-4X24 - Best 1-4X

Steiner P4Xi 1-4x24

If you're looking for your first, high-quality LPV optic for duty-intended purposes and patrol use, the Steiner P4Xi is the best AR scope for you.  It has everything going for it including a reasonable price, illuminated reticle, and true 1x magnification.

It was named Optic of the Year by a well-respected publication and received a Golden Bullseye Award by the NRA.

Pros:

  • Price
  • Illuminated reticle
  • 5.56 reticle
  • Low profile turrets
  • Made in USA

Cons:

  • Slightly mushy turrets

For some reason, the P4Xi is one of the best kept secrets in the LPVO market.  We think the doors need to be blown wide open so AR-15 owners can mount their rifles with the best scopes available.  It's intended and designed as a law enforcement scope, but it's also used a lot in 3-gun competitions.

The center-dot illuminated P3TR reticle is extremely popular.  It doesn't overwhelm or distract the sight picture.  With a 200 yard zero, the BDC hashmarks will reach out to 600 yards.  It's designed for 5.56 mm 62 gr or 7.62 mm 175 gr loads - ideal for the AR-wielding shooter.

The illumination turret has "off" positions between each brightness setting.  To maintain its effectiveness at all hours, the illumination turret has 11 intensities: 5 daylight, 4 low light, and 2 night vision levels.

Elevation and windage adjustments are in MOA with .5 MOA clicks.  While turret quality has said to be slightly mushy (not as crisp as some would compare to Vortex), just zero your scope and forget the rest out when holding over to 600 yards.

The Steiner AR-15 5202 scope is made in the USA, is affordable, and has all the right features to see you through patrol or your competition shoot.

7. Primary Arms Gen III 1-6X24 SFP ACSS - Best 1-6X for the Money

Primary Arms Gen III 1-6X24
Image Credit: Primary Arms

What would you give to own an LPV that has incomparable quality and features in its price class?  Most would give months of research, work several overtime shifts, and hem and haw in frustrating indecision before pulling the trigger.

With the Primary Arms 1-6x24 scope, you don't need to do any of that!

Pros:

  • Price
  • SFP/illuminated reticle
  • ACSS reticle
  • Capped, low-profile turrets
  • 30 mm tube

Cons:

  • Quality control issues

It's all too easy to assume the best scopes come with the highest price tags and most of the time, it's true.  However, this PA 1-6x scope is the best rifle scope in its price range for under $300.  Without illusion, it's an entry-level LPV, but it has all the right features in all the right places.

The illuminated SFP ACSS reticle is the major selling point.  Being in the rear focal plane, it won't become too small or thin at 1x.

The Advanced Combined Sighting System Reticle (ACSS) is just that - a complete system.  With it, you have BDC holdover hash marks that reach out to 800 yards compatible with 5.56, 5.45, and .308 cals, windage holdover points, moving target leads, and a vertical range estimation chart built-in.

Although the glass-etched reticle system is full-on, it's neither overwhelming nor obstructive.  It's been improved with a center Chevron aiming point instead of the dot with a segmented circle surrounding it.

With clicks in 0.5 MOA, a 30 mm tube body, and capped, low profile turrets, it's obvious it's a scope that's intended for fast shooting applications without compromising accuracy.

However, quality control issues range from poor illumination to reticle issues that may require warranty coverage.  Good thing it comes with a Lifetime Warranty PA will stand behind.  You may be willing to give an arm and a leg to own one of the best and most affordable LPVOs around, but with this scope, you don't have to.

8. Aimpoint PRO - Best Fixed Front Sight

Aimpoint Pro Patrol Optic
Image Credit: Aimpoint

This Aimpoint optic isn't just a "pro" sight, it's a Patrol Rifle Optic (PRO) that's ready for duty use when duty calls.  No, it's not an LPV scope, but it's earned its place in the list with its long history of success on the line.

If you have a CQB, carbine, short barreled AR type rifle, the Aimpoint PRO is perfect for your needs.

Pros:

  • Price
  • Red dot sight
  • Compatible with front sights
  • Transparent rear flip cover
  • Compatible with NV devices

Cons:

  • Quality control issues

The PRO has been a fan favorite for a long time.  Since it's had a long run of being tried and tested, there are various quality control issues that users report, such as poor illumination, battery life issues, and inability to move/adjust the red dot.

Moving on to the good, the Aimpoint sight comes complete and ready to mount with a QRP2 mount and AR 15 spacer.

Lens caps also get thrown into the buy with the rear cap sporting a transparent, clear cover.

Why see-through?

Even with both caps on the sight, you can still use and see your 2 MOA red dot in emergency situations when you need rapid and instant target acquisition.  When you don't have time to flip off the covers, simply keep both eyes open (as you should) and the see-through cap will allow you to see the dot.

It's compatible with fixed front sights for AR 15 platforms as has been reported by several users.  The objective bell is threaded if you want to screw in an anti-reflection device for the objective lens.

The Patrol optic is a tactical sight that was born for fast and instantaneous use for duty or home defense scenarios.  It's ready when you are!

9. Vortex Optics Strike Eagle 1-6X24 - Best Value

Vortex Strike Eagle 1-6x24
Image Credit: Vortex

The Strike Eagle LPVO scopes from Vortex are incredibly popular scopes for first-time LPVO options for the AR-15. The Strike Eagle 1-8x is highly rated, but if you want to keep the budget as low as possible, the 1-6x model is the cost-conscious model.

Pros:

  • Price
  • Glass-etched reticle
  • SFP reticle
  • 0-600 yards
  • 30 mm tube

Cons:

  • Tight eyebox

The 1-6x LPVO has 3.5” of eye relief – very good specs on paper but the eyebox has been described to be tight at max 6x power. This makes it difficult for fast engagement at max magnification via offhand shooting. However, at the bench you have time to gain a consistent cheekweld and get within optical alignment.

Speaking of the bench, the redesigned BDC3 reticle now only illuminates at the center dot and segmented horseshoe. This has the potential to improve accuracy for long-range work in supported shooting positions.

Given that it’s a SFP reticle, it does not change size throughout the power range and the illuminated portion is easily visible in the lowest powers. However, you either love the BDC compensation out to 600 yards or you don’t as some find it too small and busy for offhand work.

As an LPVO, it’s made to work with both-eyes-open at 1x magnification, and while definitely doable, there is some level of fish-bowl effect/distortion around the FOV at 1x. Only you will be able to determine your tolerance level for it.

Given that this scope runs at a budget price point for a LPVO and is covered via the VIP unconditional, lifetime warranty, it’s a compromise many are forgiving of.

10. Bushnell AR Optics 1-6x24 – Best Entry Level LPVO

Bushnell AR Optics 1-6x24
Image Credit - Bushnell

As the name suggests, the AR Optics 1-6x24 rifle scope is an ideal starter LPVO for the AR platform. Backed by the Ironclad Warranty, low price, and features suited to hunting and range work, the Bushnell scope is a value kind of buy.

Pros:

  • Etched reticle
  • Illuminated reticle
  • Capped turrets
  • Lightweight
  • Fog/waterproof

Cons:

  • Build quality issues

Though the AR Optics 1-6x scope has a 30mm tube with 14.6 mil of adjustment travel, it’s not really suited to dialing in or for extreme long-range work. The turrets are capped, they lack a zero stop and locking mechanism, and the drop reticle provides for holdovers out to 500 yards anyway. However, the caps make for confident stalking in the brush or bouncing around in the truck cab knowing it’s not unintentionally moving.

It has the SFP BTR-1 reticle with an illuminated center dot and horseshoe. It’s calibrated for.223 and 5.56 rounds though you can use it with other calibers, but you’ll need to calculate the actual distance of each BDC mark. To make speedy power changes, the AR Optics scope comes with two different length throw levers.

For a LPVO, it ranks in as one of the lightest in the market weighing only 16.5 oz. Add to that a mount and you’re still well under 2 lbs. It’s suitable for use in weather as it has a IPX7 rating and is nitrogen-purged.

The downside is there have been reports of some quality control issues from not holding zero to canted reticles and an impossibly difficult to remove battery cap that houses the CR2032 battery. Zero and reticle issues are legitimate quality concerns. Fortunately, it’s backed by the Ironclad Warranty. For a starter scope, the AR Optics 1-6x is a fair buy if you’re looking to stay under budget.

11. Burris RT-25 5-25x56 - Best for Target Shooting

Image Credit: Burris

If you’re already accustomed to the MRAD-based system, there is essentially no learning curve involved. The RT-25 is made for MIL shooters, precision shooters, and long-range shooters. If you shoot, the Burris RT-25 is made for you.

Pros:

  • Long-range
  • SCR-2 MIL reticle
  • FFP reticle
  • Side focus
  • Locking turrets

Cons:

  • No MOA

There are plenty of LPVO scopes well-suited to the AR platform, but some like to take their .223 loads out to max distances just because. This is a scope that can get it done.

The wide power range, optics to keep up, and MIL turrets and reticle will get your AR-15 hitting steel at distances you couldn’t reach before. The RT-25 has a MIL tree style reticle that was designed by professional shooters and 65 MOA in travel to get you on target. It has plenty of room to dial in and holdover to make long-range possible.

While setup for long-range use, the scope is extremely comfortable sitting in for competition use, hunting big game, and it also has the makings of being a great long-range varmint scope. It also has hallmark tactical features such as a 30mm tube, locking turrets, zero stop, and a throw lever that can be repositioned as needed.

When you want distance from your AR, you need a long-range scope. When you need budget on your side, you need an RT-25 long-range scope. End of story.

12. Zeiss Conquest V4 3-12x56 – Best Under $1000

Zeiss Conquest V4 3-12x56
Image Credit - Zeiss

Overall, the Zeiss Conquest V4 is a highly recommended hunting scope and is likely seen on a bolt action rifle. Thinking broader, equip it to an AR-15 or AR-10 for predator and varmint hunting. As one of the top hunting scopes at a reasonable price point from Zeiss, the AR shouldn’t be left out.

Pros:

  • Price
  • Lowlight
  • SFP reticle
  • Lowlight
  • Lightweight

Cons:

  • Not made in Germany

While Zeiss is famously known for their German glass and manufacturing, in order to bring the Conquest series to market at an affordable price point, they are made in Japan. This may be a drawback for stalwart loyalists. Though, Japan is the manufacturing home to many mid-range to high-end optics brands known for top-shelf optical quality.

Beyond where it’s made, it’s difficult to find fault with the solidly built and high-performing Conquest V4 scope. With its 3-12x configuration, it’s excellent for predator, big game, and target shooting applications. With a huge 56mm lens, it’s also a lowlight champ.

This Zeiss scope has illuminated dot (Z-Plex #60) and non-illuminated (Z-Plex #20) reticles. It’s a very simple, clean reticle with thin but bold center crosshairs located in the second focal plane. Due to the boldness, it’s easily visible in last legal light but thin enough not to cover vitals. Turrets are in ¼ MOA adjustments with 70 MOA E/W total travel.

Even with the large objective and 30mm tube, the Conquest weighs in at 21.5 oz. It’s been harshly tested for shockproof and corrosion resistance having been exposed to 24 hours of saltwater spray, 1500 G-force recoil tests, and 90-minute continuous vibration tests. It’s submersible in up to 13ft of water for two hours and extreme temperature tested from -13 to 122-degrees F in a period of 15 minutes.

The Conquest V4 is a tough scope. Needless to say, it can handle sitting on an AR with ease. Though expensive as many mid-range scopes get, for a Zeiss, it counts as an affordable one.

13. Bushnell AR Optics 4.5-18X40 - Best Budget Option

Bushnell AR Optics 4.5-18x40 scope side on
Image Credit: Bushnell

Unlike many scopes that do excellent on an AR-15, the AR Optics series by Bushnell are affordable. It may be what makes them so popular.

Pros:

  • Price
  • Side focus
  • Exposed turrets
  • Drop Zone 223 reticle
  • Throw levers

Cons:

  • Large BDC dots

The standard 4.5-18x40 scope is one of the best-selling models in its series and can easily be one of the top AR-15 scopes under $200. It has high power up to 18x, exposed MIL turrets, and the reticle is specifically calibrated for the .223 Rem.

You have 18 MIL of adjustment travel to get you zeroed at 100 yards and push those bullets out to around 500-600 yards. Since the reticle is in the SFP, you’ll need to change power fast once you’ve found your target. Bushnell includes both a short and long PCL (Power Change Lever) in the box for rapid power changes when it comes time to holdover.

Although it has a BDC reticle to accommodate holding over, the 1 MOA (approx.) dots will obscure small targets at max ranges. It might not be your long-range varmint hunter, but it will do nicely for predators and big game, not to mention, AR500 steel targets.

With good glass, decent low-light performance, and a side focus with a minimum distance of 10-yards, the AR Optics scope offers a lot of versatility. It’s accurate, affordable, and most importantly, right at home on your AR-15.

The XTR II 5-25x50 is a tactical and long-range competition riflescope. Various models within this line have come and gone but the SCR-MIL and SCR-MOA illuminated reticles have withstood the market and the test of time.

Pros:

  • Long-range
  • FFP reticles
  • Zero Click Stop
  • 34mm tube
  • XT-100 knobs

Cons:

  • Glass after 20x

The high power XTR II goes on sale often and snagging it for under $1000 makes for a worthwhile buy. At this price point, there are things that can be forgiven such as its optical struggles at max power. Brightness and clarity are lost, and illumination is difficult to see in daylight bright conditions.

However, with 11 brightness settings, it will perform well in lowlight conditions. Unlike some of Burris’ reticles where only the center dot is illuminated, the SCR-MIL and SCR-MOA reticles have extended illumination encompassing a well-balanced portion of the crosshairs.

SCR stands for Special Competition Reticle, they are in the FFP, and they are simple, uncluttered and easy to use. Both models have XT-100 click knobs for 100 clicks per rotation and feature Zero Click Stop for a precise, hard return to zero. The mil-based scope has 0.1mil adjustments and the moa scope has ¼ moa adjustments.

The 34mm tube allows for more adjustment travel to push beyond 1000 yards, and it does make things a little more expensive given that you must use 34mm rings. The XTR II is a heavy scope weighing in at 32.10 oz and is 16.31” long. It takes a CR2032 battery to power illumination though the reticle can be seen without it. Its minimum focusing range is 50 yards via the stiff side focus that will break in after a short time.

There’s a lot to like about the Burris competition and tactical scope and a few things you may need to evaluate. But with the Forever No Questions Asked Warranty to boot, it’s recommended as a high-performing scope if you can get it for under $1000.

What to Look for in the Best AR-15 Scopes

How do you narrow down what's most important in a scope when there are multiple budgets and shooting contexts to consider?  The answer: we don't, but you must.

Choose the scope that has the right combination of features for your shooting needs.  Is coyote hunting your primary shooting activity? You will be best to consider scopes ideal for AR-15 coyote hunting. Are you going to be out after dark? You will need to check out AR-15 scopes with night vision.

Too many times we see someone return or rap on a quality scope because they expected or wanted more of something the scope didn't claim to have in the first place.  What you need will very likely look different to someone else's needs, but you're not buying a scope for them, you're buying it for yourself.

The best scope you can mount to your AR/MSR platform is the one you recognize as best-suited for your needs.  What features do we recommend you consider?  We're glad you asked!

Budget

Not debatable is the fact that your budget is "the" ultimate deciding factor in what scope you buy for your AR-15.  Many drool and secretly envy those who can spend more than $500 on a scope.  Most of the time, shooters are looking for the affordable option while still having a chance to buy something high quality, name brand if possible, and with a bunch of honest reviews behind it.

It's easy to over-spend or think you need this or that in an AR scope.

Stick to your guns and choose the scope with the combination of features that has what you need so you don't pay for features you don't.  That's how you save money and up value in your buy.  The gems are out there, just filter through our lineup or AR-15 scopes to see what fits your budget best.

AR-15 Scope Magnification

If there's a feature that can be as versatile as its variable nature, it's magnification.  Many looking to replace their AR-15 red dot sight with an LPVO still want to retain point-blank range, close range, and rapid target acquisition benefits.  Scopes with true 1x should be able to co-witness with iron sights and provide the same POV (Point of View) as a red dot.  LPVOs that fit the bill come in 1-4x, 1-6x, 1-8x configurations.

However, not everyone shooting an AR is looking for CQB, duty, tactical, or close-range hunting benefits from an LPVO that low power provides.  Various MSR platforms have cartridges capable of stretching the distance 400, 600, 800 yards plus some.

Higher power optics can help to identify where you want to hit the target.  Additionally, the further the distance and the smaller the target is a situation requiring high magnification.  It's not uncommon to find long-range scopes on AR platforms with various power range configurations of 3-9x, 4-16x, 6-24x, and more.

Reticle

This may be one of the most important features to muse over when considering AR optics.

You may want to look for a riflescope reticle that is:

  • Illuminated
  • Has BDC/trajectory compensating dots/hashmarks
  • Various crosshair styles including duplex, Christmas-tree style, etc.
  • Simple with a dot, chevron, or circle pattern
  • Calibrated for a specific cartridge or caliber

Again, being activity-specific will help to narrow down what type of reticle will be best for you.  Simple, uncluttered, illuminated reticles are excellent options for rapid target acquisition in close quarters for fast response situations.  Complicated reticles with windage and BDC holdover points may better suit a hunter or long-range shooter.

FFP VS SFP

First or front focal plane reticles are typically a high-end feature that usually means more cost.  Shooters appreciate being able to holdover regardless of magnification whereas second or rear focal plane reticles can only be used for holdovers at max magnification.

The downside to FFP reticles is they are often too small and thin to see at low power whereas SFP reticles retain their size their regardless of magnification.

This is a subjective feature that you need to know about as it can enhance the way you shoot and directly affects your scope budget.

Eye Relief

We all know enough eye relief is extremely important to avoid scope eye.  But, avoiding the tell-tale sign that your scope is mounted in the wrong position or it doesn't offer enough eye relief is just one factor to consider.

Having enough eye relief ensures you can take advantage of the full field of view (FOV) and minimize eye fatigue.  Following moving targets and long observation through a scope requires generous eye relief.  Adjustable eye relief may also be very beneficial to those with adjustable stocks.

Mounts, Extended Mounts, Rings & More

Do you want your scope to clear your iron sights?  Do you need an extended mount?  Do you have the right size rings?  Is a quick release/detach mount a realistic feature worth paying more for?

Because the AR platform is extremely modular, you will want to consider what accessories will best suit your rifle and scope system.  Some scopes come with included mounts and rings.  Most of the time, you're going to have to save room in your optics budget for the necessary accessories.

AR-15 Rifle & Scope: The Versatile Choice

As you build and upgrade your AR-15/MSR over time, you might find you'll need to do the same with your scope as your needs change.  Not every scope is a one-size-fits-all option, and neither should your approach be the same.

Size, weight, weatherproofness, and glass quality are just as important to keep in mind as the suggested recommendations listed above.  It can get daunting trying to think of every facet to research, so if you can get out there and test drive some different scopes, more power to you and your buy.
