Best AR 15 Scopes & Optics Reviews

1 Vortex Optics Crossfire II 1-inch Tube Riflescopes (Overall Best)

Vortex spells quality and they have incorporated many features in this low powered scope. The 1-4x is for short-and mid-range shooting. The scope is constructed of a single tube from aircraft-grade aluminum. Both shock-proof performance and strength are assured. Nitrogen purged and O-ring sealed, the Crossfire II is fog-and water-resistant.

The magnification range is 4-12x and the objective is 24mm. The Dead-Hold BDC reticle supports varying ranges. The eye relief is long. Getting a sight picture is swift and easy to acquire. The reticle focusing is provided with a fast-focus eyepiece.

Fully multi-coated lenses are anti-reflective and provide crystal-clear bright views for the user. The reset turrets are capped and are adjustable by finger with MOA clicks that after sighting in can be reset to zero. Having nominated the Vortex Optics Crossfire II as our top Choice, we need to justify our research.

The lenses are splendid, durable and the reticle is illuminated but lens caps are not provided. This is not for use on scout type rifles as the image will wash out with higher magnification. The red dot works flawlessly. Also, the zero holds true after sighting in. It is a well-engineered product and overall, we stand by the Vortex Optics Crossfire II. It’s a winner hands down.

The Crossfire II has a Dead-Hold BDC reticle for shooting at various ranges. The BugBuster is armed with a mil-dot reticle. Mounting it was easy. The magnification and objective settings are user friendly. The BugBuster is used for mid-to long-range whereas the Crossfire II is more suited for short to medium range.

The Vortex Crossfire II is highly rated and has a price range from $120-$220.

Specifications

Pros

• Affordable
• BDC and illuminated reticle option
• Zero resettable turrets
• Lifetime transferable warranty

Cons

• Glass not good enough on high magnification

Our Verdict

TheVortex Crossfire II is durable enough for most range shooting and hunting. But if you intend to really put it through the grind, you should contemplate on getting yourself a higher-end scope. The turret dial is squishy and there are no clicks.

The Vortex Lifetime is reliable and you have no fears on that count. The Vortex Crossfire II is worth its price but for a few bucks more, the Vortex Diamondback is a better buy.

2 UTG 3-9X32 1? BugBuster Scope (For the Budget-Conscious)

When it comes to looking for a budget-friendly rifle scope for the AR-15, the UTG is among the more favored and is worth checking out.

The Bug Buster is a hardy, versatile scope. The exterior tube is 1-inch, 9.8 inches long and weighs 13.9 ounces. The lens coating is made of emerald for ultimate light transmission with a 2-inch sunshade. Two heavy-duty mounting rings and two lens caps that flip open are provided.

The scope is variable and includes a 32mm objective lens with 3-9x magnification. This is an ideal magnification range for both mid and long-range. Generous eye relief is provided. A mil-dot reticle for range estimating is fitted. The scope comes with an impressive dual green/red illumination. Illumination is adjusted by means of a side control wheel.

The turrets of the UTG Bug Buster are lockable and resettable, permitting adjustments to windage and elevation. Different weather conditions do not adversely affect this scope as it is totally sealed and filled with nitrogen.

This is the product we narrowed down as our best budget AR15 scope. We ran our own trials on the Bug Buster and found it delivers big. It mounts easily and can be used both for hunting and shooting. As far as durability and toughness go, it passes with flying colors.

High-quality materials were used for its construction. Recoil and battering have also been rigorously tested. A rather grave problem we faced was the windage setting, even at 25 yards was quite off.

The scope zeroes well, the turret moves fluidly with smooth, sharp clicks. The magnification adjustment proved a bit stiff. Higher magnification introduces blurry black edges. The ocular rings are trouble-free and the scope looks and feels well made.

Specifications

Pros

• Good pricing
• Zero reset/ lockable turret
• RGB Swat (Side Wheel Adjustable Turret) illumination
• TS (True Strength) Platform
• Included rings

Cons

• None that we could think of

Our Verdict

We wonder if there is anything they have missed out in adding to the features; emerald coating that offers effective light-transmission, zero resettable & lockable turrets, 1/4 MOA for every click adjustment, Mil-dot reticle and what not. On top of that, its track record is enviable. This scope is well suited for competitive shooting and home defense. Vortex is a reliable brand and so is this money-saver!

3 Trijicon ACOG 3.5×35 Riflescopes (Advanced Choice)

The Trijicon ACOG is an insanely durable and combat driven scope.

The ACOG is short for Advanced Combat Optical Gunsight it was designed specifically for the US Military, in particular, The Navy Seals for a long time. It’s housing of top-quality forged aircraft-grade aluminum. The lens is of multiple coatings that supplement its strength. It is waterproof and shockproof and it can handle a few bumps and thumps without any adverse effects.

The magnification of the Trijicon scope is a fixed 3.5x. In case you’re wondering if this magnification is a little miserly, the low power has been chosen, because the scope can then be deployed rapidly at targets close enough.

The illumination for this scope is battery-less. The illumination for the Trijicon ACOG is dual; fiber optics and TrItium. The fiber optics swing into play in daylight brightness and the Tritium glows in low light conditions. This incredible scope comes with 10 reticle options and 3 color alternatives. (red, green and amber)

The Trijicon ACOG is our Advanced choice. Based on the brightness conditions, this optic will auto adjust the illumination. The battery is illumination-free. The sight picture is amazingly clear and there is no strain or fatigue.

To tally it all up, the 3.5×35 is one combat-proven optic that most consider the best in its class. We undertook a comparison of two products in the same genre; The Trijicon ACOG and the Vortex Viper Gen II, worthy rivals. The means of reticle illumination are different, the ACOG stealing the march here.

The lens on the Viper is stellar. We were overawed. This is the most expensive of all the products we have chosen and being a premium product, hence few takers we guess.

Specifications

Pros

• Adjustable scope magnification
• Super durable optic
• Integrated rangefinder
• Dual illumination
• Mount included

Cons

• Less peripheral view
• No solid reticle

Our Verdict

Not for nothing has the Trijicon ACOG earned the respect of many users. As the choice armament of the Navy Seals, it proves its pedigree. It is a tactical scope that can also be used for hunting and shooting. Some may complain that the magnification is on the lower side but this is a tactical scope. It is combat proven and comes with a high price tag.

4 UTG 3-12X44 30mm Compact Scope (Beginner’s Choice)

For a memorable hunting experience, a great riflescope is a must. Just team it with a fabulous rifle, and sit back. This is the reason why the UTG 30mm SWAT 3-12X44 with its compact scope and AO Mil-dot has a considerable fan-following amongst hunters.

The turret is zero resetting and target zero locking. By adjusting these features, your target aiming will be bang on. A parallax range of between 10 yards and infinity works great. The IE (Illumination Enhancing) reticle is another prime feature. This customizes the illumination and multi-color mode with a spectrum that has 36 colors.

The UTG scope has emerald coated lenses and these top-rated optics come with lenses that are multi-colored. A glare avoiding angled sunshade with flip open lens caps is fitted. And now let’s take a good look at our Beginner’s choice, the UTG Compact scope. We loved the feature whereby the illumination is non-stop. This is also when experiencing heavy recoil.

The glass is clean, holds zero wonderfully and the brightness is more than one can expect. The focus knob positioned on the left is wonderful. If you are on a budget and also aiming for accuracy, this scope will have you doing hoops. Try it, you won’t be disappointed.

We are pitting two products of the same manufacturer into the arena, the UTG BugMaster (Budget Choice) and the UTG 30mm Compact Scope (Beginners choice), both inexpensive scopes, to start with. The mil-dot reticle of both is a great hit amongst hunters, making it one of the best AR hunting scopes out there. The Compact has a zero-reset and a zero lock facility. Mostly, they are evenly matched and are joint winners.

Specifications

Pros

• Wider field of view
• Illuminated, multi-color reticle
• Solid turrets
• Versatile parallax adjustment
• Eye relief range forgiving

Cons

• Large objective lens
• Light transmission can be better.

Our Verdict

The UTG Compact scope is touted as an entry-level scope but judging by the number of goodies packed in, we are a bit bewildered. This scope has been tried and tested in all forms of use be it hunting for predators and even big game which is a dead giveaway to its superior versatility. For beginners. this is definitely the best AR 15 scope under 200 USD. A word of caution, make sure the scope and your rifle are compatible.

5 ATN X-Sight II HD 3-14

Riflescope technology has traveled a long way over the years. Thermal imaging, nocturnal vision, and smart scopes are the stuff of science fiction. The AXN X-Sight II is a smart Day/Night Rifle Scope.

The ATN X-Sight combines digital imaging technology with the features of the rifle scope. The magnification of this scope is 3-14x. The night vision at HD standard, targets are visible in any condition of lighting. This night vision can be gained in green or black and white.

The X-Sight II is also a digital camera. It can take high quality still pictures and the camera records at 1080p resolution, is also Wi-Fi-enabled and can stream directly to another device. Probably the best AR15 scope out there, it allows you to automatically calculate the distance to the target you are aiming at with the built-in rangefinder.

The scope also contains a built-in ballistic calculator. This gizmo integrates the variables in your bullets trajectory and advises you where to hold to make long-range shots.

The ATN X-sight is our Multifunctional choice because we discovered it is indeed worthy of being called a smart scope. The image quality was excellent though we observed some blurring at 14x (which is to be expected). The zoom worked well and the picture quality was exceptional.

We believe this is the best night vision scope for AR 15 though there’s no thermal. The recoil activated video though turned out mediocre. This scope is a battery guzzler. A micro-SD card should have been included but it isn’t. There is no windage or elevation setting. Zeroing is by auto-calibration. If your AR15 has a carry handle, it will still work.

We can convincingly say, the ATN X-Sight is what it claims to be. It is an exceptional riflescope. Its closest rival is the Burris 200261 which is cheaper. It performs well though can’t be said to be at par with the ATN.

Specifications

Pros

• Night vision capability
• Built-in rangefinder and ballistic calculator
• Record HD videos and photos
• Stream to other devices
• Low cost

Cons

• Adds weight to the rifle
• Requires frequent battery changes

Our Verdict

That the ATN X-Sight is described as a multifunctional choice is apt. It is truly a smart scope and accordingly outplays the competition on several fronts. The day/night vision, the ballistic calculator, the in-built camera; you name it. At the price it is offered at, one would be tempted to grab it. But a sensible choice would be to take your time, try the features, read as many AR 15 scope reviews as you can before you make a final move.

6 Vortex Optics Spitfire EBR-556B Reticle (MOA)

Vortex Optics have recently gained ground as the manufacturers of the superb optic around the world.

The Spitfire 3x is devised to function as the optic that any rifle utilizing a 5.56 cartridge The Spitfire 3x has high recoil potential and is a good fit for semi-automatic weapons. Its uses are multifarious- hunting, tactical shooting, police work and competitions as the precision of its targeting aim and accuracy is peerless.

The Vortex Spitfire optic’s weight is 12.2 oz.and 5.5 inches in length. It was devised as a near replacement to an ACOG optic, though unfairly alluded to as the “poor cousin of the ACOG”.

The Spitfire has a fixed sight magnification but it does its task as a mid-range top-quality gun with aplomb. This sight is well-matched with other rifles that take a 5.56 caliber cartridge. It is a workhorse in tough conditions and handles high recoil efficiently, which makes semi-automatic weapons compatible with it.

The optic holds zero unerringly while the EBR-556B (Enhanced Battle Reticle) reticle is matchless in making distance measurements striking the target accurately. The reticle can be used at differing ranges using the varied markings. You can pick between many illumination colors. Five intensity levels are present. This really works wonders for different lighting conditions.

What grabbed us straight up was the ‘always ready platform’ of this beauty. We found this rifle scope pretty underrated. For many years, fixed prism scopes have been on the top of the game owing to simplicity, compact and reliable design. This culminates in the Spitfire 3x. The custom BDC reticle takes out any guesswork from 0-500 yards.

It is a mid-range scope with a lifetime warranty.

Specifications

Pros

• Affordable
• Independent reticle
• Flip caps
• Adjustment for height
• Five brightness settings
• Prism Optics

Cons

• Weight on the heavier side
• Fixed magnification

Our Verdict

Vortex Optics is always a reliable brand and this scope lives up to anyone’s expectations. It can be fitted on a wide variety of rifles. The batteries are powerful that last between 150-3000 hours depending on usage. The reticle may appear thinner or smaller, especially for older shooters. These scopes have pedigree and are the last word in ruggedness. Make sure you are buying your scope from an authorized dealer or your warranty is void.

7 Nikon ProStaff 3-9 x 40 Black Matte Riflescope

Nikon is a name that does not come as a surprise to anyone. Their skill is carved in stone. The Nikon Prostaff Rimfire 3-9x 40 is from their stables. Though this scope is inexpensive, full functionality is guaranteed and the device is made to last given its rugged durability. It is patented by Nikon’s full lifetime warranty.

The parallax is set at 50 yards so if you are sighting at 25 yards or less, you could experience blurring as parallax adjustment is not possible. It is crucial that the rifle, scope, and bullets are matched. Nitrogen -purging ensures that the seals do not allow any moisture making the scope totally fog-free.

The ProStaff 3-9 rifle scope supplies a BDC reticle that is 22 LR-specific. The parallax setting is 50 yards. The zero-reset turrets are spring-loaded. Nikon’s multicoated lenses render an exclusive sight picture. The optical system that is fully multi-coated provides light transmission up to 98%. The eye relief of this rimfire scope is a comfortable 3.6 inches.

A fair review means refusing to be browbeaten. Sure, it’s a Nikon and a great scope for a .22. The scope was crystal clear and focused steadily. The BDC reticle was wonderful. We discovered that it was possible to transmit to the Nikon website that will calculate ranges and hold points in the BDC.

Parallax adjustment is not provided which is a bit of a letdown. We say, with much confidence that you cannot source a scope at this price. The Burris 200621 and the Spitfire 3x compare well being in the same price range; the former a little under $350, the later a little under $400.

Specifications

Pros

• Easy to set up and adjust
• The Spot on software makes it super accurate
• Takes less zeroing time with the auto-adjust turrets
• Good value for the money

Cons

• At close range, the scope may be blurry

Nikon is a name you are familiar with and this riflescope runs out the competition. The Nikon Buckmasters II is Nikon’s top launch. With a 40mm objective lens and magnification range 4-12x, the picture is crystal clear, your target cannot elude you.

The Buckmasters II comes with a brawny, durable body structure. It harvests light which enables shooting even if it’s dark outside. The optical system being multi-coated has the means to transmit 98% light irrespective of the ambient light. A generous eye relief of 3.7 inches has been incorporated.

This scope’s tube is nitrogen-filled, insurance against fogging over, shockproof and waterproof. Long-range shooting was a bit problematic. The built-in BDC allows exceeding this range. A ballistic circle view is incorporated. Adjusting for around 300 yards is simple.

This scope is provided with a spring-loaded knob integral with the zero-reset knob. Excessive sunlight is a deterrent for the shooter and the adjustable sunshade. We know for a fact that the Nikon Buckmaster II was a rifle scope much coveted. Our review made it amply clear that at the price offered, holding back could be a disaster.

The two scopes we could not resist to compare are the Buckmaster II and the Nikon Prostaff. The Buckmaster II has a greater magnification and the reticle is standard BDC. The Prostaff is equipped with the BDC LR-22 reticle. One of the best cheap AR scopes out there, it has been fairly reviewed by other sharpshooters as well.

Specifications

Pros

• Simple to use the zero-reset turret

9 Vortex Optics Viper HS-T Second Focal Plane Riflescopes

We loved the Vortex Optics Viper as it was worthy of all types of firearms. It has been made sturdy by cutting from a 30mm tube. With adjustable turrets super clear scope they’ve offered a compact package here with a myriad of excellent features.

Viper is designed to perform for all ranges of shootings– long, mid and short– the credit goes to its 6-24x magnification capacity. In terms of field of view and image clarity, this 50mm stands out from the rest for clarity and image resolution. They’ve also added 4″ eye relief will make it easy for the eyes. You wouldn’t have to dread the so-called ‘scope bite’ anymore.

Coated 1-piece anodized aluminum has been used to construct the body of the scope. They’ve also made it waterproof and the high-end engineering ensured it to be argon purged for being fog-proof.

Designed to be held for long-range shots, the scope features VMR-1 reticle model which is functions independently from the magnification process, thanks to its design that allows a second focal plane carrying hash marks. This type of reticle supersedes the performance of a red dot optics when performing in windy conditions. If you are up for moving targets, this VMR-1 reticle, although not illuminated, shines there too.

With strong MOA turrets and parallax adjustments, this scope is absolutely fun to use. One downside we found about it is that they haven’t included the mounting with the package. The Vortex Viper comes with VIP warranty coverage.

We closely examined the build quality of the scope and it made us happy with its overall construction. Nonetheless, we found it a bit on the heavy side. The overall design appeared a bit bulky for us, not to mention that it is 16-inch in length. We found signs of edge blurring when pushing it beyond 24x magnification, the achromatic aberration is also there. What impressed us is the clarity of the central focus area.

Despite being a digitally advanced and capable scope it can easily be compared to ATN X-Sight. We’d say this is an excellent all-around option for your AR 15 rifle.

Specifications

Cons

• A bit on the heavy side
• Vision clarity could be better

Our Verdict

It is downright hard to find another scope that can do what this one does. It is in a league of its own. If you look beyond the incremental weight difference and the length, you will see a scope that is great for all ranges to shoot with, is a study in craftsmanship and sturdiness. The construction is rock solid. For the sheer weight of the features it offers, this scope is amazingly low-priced; almost a giveaway.

10 Bushnell Optics Drop Zone Reticle Riflescope

For hunting expeditions and shooting at long-range specifically, the Bushnell AR optic fits the bill. Even when engaged in dreary lighting and dismal weather conditions, the Bushnell Optics has come out on top with its proven enhanced precision scope.

An indisputable functionality is the parallax correction that is side focus, a showpiece of the Bushnell riflescope. This functionality rectifies parallax errors which go some way in bestowing near-flawless precision at all shooting distances virtually.

A reticle that is BDC ballistic and drop zone is featured on this scope. This reticle is in a class of its own and races in at roughly 104 yards. Not only that, but it also has aiming points accurate to 500 yards.

It is a second focal plane scope. The crosshair may be a bit dense for some folks but we believe this is not a big issue.

Beyond, the zero was wandering. The magnification is a bit restrained for anything beyond the medium-range. We were thrilled with the side parallax focus. The Bushnell Drop Zone scope is a gem; easy to use and devoid of frills. It has a single agenda that delivers accuracy.

Specifications

Pros

• Side focus parallax
• Easy to use
• Well made, durable and sturdy
• Great optical quality

Cons

• May be hard to mount using low rings
• Drop zone reticle may be hard to sight

Our Verdict

The Bushnell AR Optics riflescope is one that is impressive for the price, especially when you compare it with other Bushnell scopes like the Elite Tactical LRTS 4.5-18×44 G3 FDE that comes at around 1000 USD. Multi-coated lenses, parallax adjustments, and similar features being routine on more expensive scopes, you are in for a bit of a shock when you look at the price tag. With a magnification power of 3-9x, we highly recommend this amazing scope to competitive shooters and varmint hunters who want the best of their weapons.

11 Vortex Optics Viper PST Gen II First Focal Plane Riflescopes

Vortex, a well-known name in the field of optics is the creator of this masterpiece, the Viper PST Gen II riflescope.

This is a great long-range scope because the illuminated first focal plane reticle and tactical style turrets make it simple to recompense bullet drop and wind drift at long ranges. The Rapid Return Zero (RZR) design halts the turret from misaligning below the original zero after a compensated long-range shot.

Resolution and color trueness is increased by using extra-low dispersion glass. This gives you a crisp, sharp image. All air to glass surfaces is fully multi-coated with anti-reflective coatings to boost light transmission. The exterior of the lens surface features Vortex’s patented ultra-hard ArmorTek coating to safeguard against oil, dirt, and scratches. The body is of 1-piece, 30mm tube of aircraft-grade aluminum.

To promote concealment, a durable hard-anodized low glare matte finish is applied. The Viper PST Gen II scope is O-ring sealed and argon-gas purged for that cent percent waterproof and fog proof dependability.

The EBR-2C MOA reticle for calculating windage and elevation compensation. This riflescope is covered by a VIP Unconditional Lifetime Warranty.

We would like to put in a word here. Vortex Optics is our all-time favorite. The bad news first; zero does not hold. The manufacturer made adjustments and all was hunky-dory. The reticle illumination for daytime does not quite cut it. It’s all up from here especially the lens that we simply felt was a sublime piece of optical engineering.

Our Multifunctional choice, the ATN X-Sight is a good comparison with the Viper Gen II which may not be high-tech but it sure delivers the goods. The centerpiece, the lens is superior to the ATN. Eye relief is a bit constrained.

Specifications

Cons

• Good for medium to long-range only
• Eye relief inadequate at lower magnification

Our Verdict

Vortex is no Johnny come lately in the field of riflescopes. The Viper PST Gen II is a stunning piece of optics and bears testimony to the skill and professionalism of Vortex. What took our breath away was the superlative optical arrangement and the care and expertise that has been put into ensuring the lens is well protected. The price point is on the higher side but we personally believe this is the best scope for an AR 10.

Best AR 15 Scopes [Buying Guide]

1. Magnification

Scopes are often tagged with the numbers 3.9 x 40. The first figure is the magnification range of the scope, which means that objects are visible at least 3 times larger than the naked eye, The second figure denotes the size of the objective lens. The larger the objective, the more light is transmitted and the clearer the image.

For long-distance shooting in open ground, a scope with a minimum magnification of 9x is recommended. This has to be teamed with a lense large enough for peak light transmission, which yields clearer and brighter images over extended distances.

For close-quarters tactical settings and point-blank range, image clarity takes precedence over magnification. A 1-4 magnification will suffice and these scopes meant for close range encounters have smaller objectives rendering them compact and low profile.

2. Shooting Distances

• Ranges are classified into three broadly.
• Close – up to 150 yards
• Medium – 150 to 350 yards
• Long – 350 to 800 yards

3. Reticles

• Duplex– These are widely known and are the basis of reticle types. And similar to the magnification, depending on the use of your AR-15 will dictate the choice of the reticle. The duplex reticle is straightforward and common. Quick target acquisition is its hallmark. It features a cross, the edges being marked with thick lines and thinner lines at the intersection point. Some scopes have a duplex reticle for long-range shooting to gauge distances accurately.
• Mil Dot– In appearance, the mil dot reticle is hardly any different from the duplex. Etched on the scope is a simple cross. The main difference between the two is that the mil dot reticle always includes a set of markers for the estimation of the distance in both horizontal and vertical planes. Marksmen and hunters who relish long-distance shooting prefer the mil dot reticle.
• BDC– The BDC reticle figures in the effect of gravity on the fired bullet. The aim needs to be higher in long-distance shooting and the measurements needed to compensate for the drop in the bullet are provided by the BDC reticle. Scopes designated for extremely long-range shooting are invariably equipped with the BDC reticle.

For precise target acquisition in low-light conditions, illuminated reticles are used. They make it a lot simpler to pick out the target in dark conditions.

4. MOA or MRAD

To harness the full benefits of your scope, you need to calibrate it. You need to understand the correlation between an inch on your scope’s motion and the field distance is. Herein enters the minute of angle, a mathematical equation. It could be a bit complicated to understand but the benefits are manifold once you get the hang of it.

The first step is to divide the circle into 360 parts called degrees and further subdivide each degree into 60 equal parts called minutes. The matter becomes imperative when sighting your new scope. Extreme accuracy is called for as due to identical triangles, any error propagates and grows.

As is apparent, one MOA dot enlarges to 1-inch at every 100 yards. The knobs help you fine-tune the scope till you zero in.

5. Objective

The objective lens is the one on the outer side of the scope. The larger the objective, the more light it will allow in which renders the image clearer especially in low-light conditions. Larger lenses are bulkier but they also offer a larger field of view.

Another important parameter is the exit pupil. This is the amount of light emanating from the scope. It is derived by dividing the objective with magnification. So an objective of 32mm with a power of 4 will give you 8mm. By day, the human pupil varies from 2-4mm; at dawn and dusk, this goes up to 5-9mm. In low light conditions, it is desirable to get as much light in your eye as possible.

6. Focal plane

The etching of a reticle is either in the first focal plane or the second focal plane. This means that in the FFP it is positioned near to the objective lens and in the SFP, it is closer to the ocular lens and eyepiece.

When set in the first focal plane, the reticle is magnified along with the image whenever the magnification power of your scope is adjusted. In other words, when you zoom in a scope with a mil-dot reticle, the small markers become enlarged with enhanced accuracy over long distances.

A reticle situated in the second focal plane behaves the opposite. Regardless of the magnification of the scope, the reticle remains the same size. Which configuration to use is strictly on the application and the user’s preference.

7. Parallax Adjustment

When the focal plane is misaligned, it is termed parallax. It is easy to test and see if the parallax is present in your scope. Sight your target via this scope at a range of 100-110 yards. After being on the target, move your eyes to a different part of the target and watch for any image movement. If you spot any difference, parallax is present.

This can be corrected using the scopes adjustment for this problem if such an adjustment is included in your scope. If your scope doesn’t have a dedicated parallax adjustment, you will need to sight the scope again. The downside is that if your scope has parallax you cannot correct it in the field.

• • Marker-Based Augmented Reality
  • Markerless Augmented Reality
  • Projection Augmented Reality
  • Superimposition Based Augmented Reality

9. Eye Relief

This is the distance that a scope can be held comfortably from the eye and still allow the shooter to sight the entire view. It is stated as a range since in a scope with variable power, the eye relief will vary with the power.

A lateral adjustment can be made with the mounting to get the optimum eye relief. 3 to 4 inches is the norm. On large magnum rifles, maximum relief is desirable as the recoil can be large and the possibility of eye injury exists.

10. Accuracy and brightness

Any shooter will wager that a scope without clarity is a dud. More so during hours of dawn and dusk. This goes hand in hand with the brightness which is equally principal.

Accuracy is the focal point of every gunsight and rifle scope in the world, especially when you are after the big game at close quarters. You may get just that one perfect shot!

Cleaning & Maintenance Tips

The most common cause of damage to a lens is a fall. The second is water, dirt not being removed or removed improperly. To clean the lenses, you’ll need:

• The most common damage is breakage
• Promptly remove water or dirt from the lens
• Use quality lens cloth or brushes
• Brush the dust off first before using the cloth on the lens
• Keep the lens cap on when not in use

Dos

• Tap the lens with the optic pointing downward for the dust to drop off
• Get a lens pen, lens brush or a soft-bristled brush
• Make sure the dusting tool is clean of debris and oil
• Allow debris to fall off by lightly brushing the lens
• If you’re using a lens pen, allow for a tighter bristle group by retracting the brush to loosen up tough buildup
• Use the microfiber cloth in a circular motion to clear away smears

Don’ts

• Don’t use your shirttails to wipe the lens. They are abrasive and will scratch the lens
• Don’t use your handkerchief since it might be contaminated
• Don’t use your sleeve to wipe off condensation

FAQs

Q. 1: What is the optimal magnification for an AR-15?

Ans. The AR-15 is a tactical weapon, though many Americans also use this to rid their properties of coyotes, foxes, and other varmints. Assuming that this is the case, the magnification you will need is between 5x and 9x, not from 1x to 6x. The range is medium, which is 150-400 yards.

Q. 2: What are the magnification levels available for an AR 15 scope?

Ans. When deciding on the level of magnification, it is important to define what your primary style of shooting is to be. If you are going to be shooting long-range precision, then your scope magnification is going to be high.

With innumerable uses for an AR-15, the answers as to the right level of magnification are equally varied. Other reasons your shooting style will affect the magnification are:

• When you are taking a shot standing, the rifle is bound to wobble. The higher the magnification, the greater the wobble.
• The higher the magnification, the shorter the field of view.
• Heatwaves and mirages increase at higher magnifications

Q. 3: What is a BDC Reticle on a scope?

Ans. A BDC reticle is designed to help you compensate for the bullet drop, which is the effect of gravity causing the bullet to drop as it travels over a distance. The reticle has markings or hash marks on the vertical axis that correspond to distances. For example, if you know your bullet will drop a certain amount at a certain distance, you can use the corresponding marking on the BDC reticle to aim higher and compensate for that drop.

Q. 4: What AR scope does the U.S. military use?

Ans. The United States military primarily uses the Advanced Combat Optical Gunsight (ACOG) as its standard combat optic for the M16 and M4 family of rifles, which includes the AR-15. The ACOG is a rugged and reliable scope that has been in service with the U.S. military since the early 2000s. Manufactured by Trijicon, it has seen extensive use by U.S. military forces in Iraq and Afghanistan.

Q. 5: Why did the U.S. military stop using the AR-15?

Ans. The military did not stop using the AR-15 rifle platform but it rather evolved into the M16 rifle and its variants, which are still in use by the U.S. military today.
