The .300 AAC Blackout is a trendy centerfire rifle caliber capable of shooting subsonic or supersonic loads. Besides military applications, 300 BLK meets perfectly hog hunters’ demands, primarily when chambered in AR-platform rifles.

Since the 300 AAC Blackout has an effective range of around 500 yards, it pairs well with red dots, reflex sites, LPVO (Low Powered Variable Optics) and anything else offering a good field of view at 1x.

In that context, we haven’t focused only on optics that use magnification but also covered red dots and prism sights and even thermal imaging devices.

Best Scope for 300 Blackout

  1   Monstrum G2 1-6×24

Currently, one of the trendy sporting optics belongs to the G2 line built by Monstrum Tactical Optics. The G2 is an updated version of Monstrum’s highly popular entry-level low variable scopes that match the 300 AAC Blackout caliber.

The Monstrum G2 line features a functional set of performance standards needed for 300 Blackout firearms, such as the first focal plane rangefinder reticle and an adjustable objective (A.O.) lens.

The FFP reticle gives you easy-to-read ranging information while it offers red and green illumination with multiple brightness intensities.

Magnification range of 1-6x and full multi-layer lens coating will provide you an accurate shot at mid to long-range big game at distances of up to 400+ yards.

This feather-weight scope has an eye relief of 4-4.5 inches, depending on magnification.

Weighing just one pound, Monstrum G2 1-6×24 rifle scope combines an aircraft-grade 6061 aluminum construction with a 30mm main tube for durability and rough use.


  2   Vortex Optics Crossfire Gen II Red Dot Sight

When it comes to red dots, Vortex knows their stuff.

The Vortex Crossfire Gen II red dot is an upgrade to the first-generation Crossfire. It is filled with features and settings that make it a great scope for a .300 AAC Blackout.

We’ll start with the optics first. It has a 2 MOA red dot that you can easily see in bright daylight. The background lighting conditions don’t have to be dark for the red dot to light up bright. It has a 1.1” viewing lens with 11 different illumination settings for you to adjust the crispness and clarity of the red dot in all lighting conditions. When you want to use night vision, just use the lowest two optics settings on the sight.

You can adjust for windage and elevation using the turrets on the top and side of the sight. Each click accounts for 1 MOA at 100 yards.

As far as mounting goes, you can mount it two ways. You can choose a low mount or a high mount, making it perfect for you to mount on your .300 Blackout.


  3   Eotech XPS2

Though often designated as red dot sighs, technically, the XPS2-0 from EOTech Optics is a holographic sight.

As the most miniature optic from the Eotech family, the XPS2-0 is based on the classic Eotech square lens design.

With a sizeable 1.20″ x 0.85 inches window, the XPS2 offers more head placement flexibility than traditional tube-style red dots.

Featuring robust construction, unlimited eye relief, and a comprehensive sight picture, the XPS2 is intended to be used for military and police applications, particularly for close quarters.

In comparison to classic red dots, the Eotech boasts a reticle designed to be dual purpose.

The 65 MOA outer red circle reticle is designed for fast target acquisition, while the internal, smaller, 1 MOA red dot in the middle will enable you to make precision shots.

At only 8oz, this lightweight holographic sight is powered by a single 123 lithium battery with an average battery life of roughly 500-600 hours at brightness level 12.

The EOTech XPS2 utilizes a protective aluminum hood around the lens. Although this small sight would occupy less rail space, making it perfect for carbines and submachine guns, the optic is durable and can withstand any home and self-defense rifles’ powerful recoil.


  4   Primary Arms Silver Series

The Silver optics line belongs to Primary Arms’ mid-range series of products and offers excellent value for money.

Primary Arms Silver Series sports the P.A. famous Advanced Combined Sighting System or for short ACSS reticle. This 1-6×24 scope comes equipped with caliber specific ACSS reticle designed for 300AAC Blackout caliber.

The innovative and illuminated two-part reticle is great for both supersonic and subsonic loads, enabling you to react fast from 0 to 300 yards and very accurate from 400 to 800 yards. The reticle is set in the (SFP), second focal plane, while the illumination system has 11 brightness settings with bright daylight Illumination.

Primary Arms Silver 1-6x is the third generation of the 1–6×24 that boasts a 30mm main body made of durable 6063 aluminum and standard, capped hunting turrets extensive internal adjustment range of 140 MOAs.

As one of the most affordable 1-6x LPVO scopes, Primary Arms Silver Series is not on par with high-class brands, but it is a worthy scope for all skill levels.


  5   Trijicon ACOG

Trijicon’s ACOG (Advanced Combat Optical Gunsight) scope is crème de la crème for rifles chambered in 300 Blackout.

It is a fixed power compact rifle scope that comes in many magnification levels, but our model is classic 4x32mm.

You can say this scope configuration is specifically designed and purpose-built for the AAC 300 to provide rapid deployment and tight groupings at medium range.

The most notable feature is the Trijicon proprietary BDC .300 Ballistic reticle with tritium/fiber optic illumination for bright to low/no light scenarios. Another selling point is a multi-coated lens system configuration designed to deliver an astoundingly bright field of view and a crystal clear 4x optical performance.

Since military people and professionals highly trust the Trijicon’s ACOG, it consists of a forged 7075-T6 aircraft aluminum-scope body that provides a nearly indestructible sighting system.

While it comes with a pretty high price tag, don’t forget that Trijicon’s ACOG is an official weapon sight for both U.S. Special Operations Forces and the Marine Corps.


  6   Eotech HHS II Holographic Hybrid Sight

The Eotech HHS II is an upgrade to the first generation HHS holographic sight. It includes an EXPS2-2 sight with a G33 magnifier. The EXPS2-2 is not night vision compatible, but it has a bright 2-dot ring reticle.

The G33 magnifier makes it easy to quickly transition from short-range to medium-range targets, which is a great feature to have when you are hunting game that’s on the move. It has 20 different manual daylight settings with unlimited eye relief.

When you want to make an elevation adjustment, simply turn the turret on top of the sight. One click on the turret will adjust ½ MOA per 100 yards.

For mounting, it has a quick-detach lever that fits a 1” Weaver mount or a Mil-STD -1913 Picatinny Rail.


  7   UUQ Green Red Dot Sight with Laser

UUQ Green Red Dot Sight with Laser

This may be the best scope for the money for your .300 Blackout. It’s just over $50 and has everything you need to get the job done.

One of the customizable options you have is to choose a red dot or a green dot. It has four different reticle patterns and seven levels of brightness for both colors. All you have to do to change the color or adjust the brightness is turn the two knobs on the side of the scope, and it will adjust accordingly.

You can also adjust for windage and elevation using the knobs on the top and side of the scope. Each click adjusts for ½ MOA.

A laser isn’t a necessity for a .300 Blackout scope, but if you get the option, then why not choose it, right? The green laser on the UUQ scope can range up to 300 yards which is great for those medium-to-long-range shots you may need to take.


  8   Primary Arms Gen III 1-6x24mm Rifle Scope

One of the best wide-angled scopes that comes with a reticle optimized for the 300 Blackout caliber is a Primary Arms Gen III 1-6x24mm rifle scope.

As a Gen III, the Primary Arms 1-6×24 SFP scope is shorter, lighter, and offers larger internal adjustment than the older model.

This 1-6x scope sports an ACSS 300BLK/7.62×39 two-part reticle with integrated bullet drop compensation, wind holds, moving target leads and range estimation.

The ACSS Standard reticle for 300BLK7.62 has a partial red illumination and features 11 brightness settings.

This rifle scope provides you an instinctive and very accurate sighting system at a very reasonable price tag.

With a price range under $300, the Primary Arms 1-6×24 Gen III rifle scope is one of the best offers on the market.


  9   Aimpoint PRO

There is no complete list for 300 Blackout platforms without some of the reputable Aimpoint red dot sights. Aimpoint Pro is a high-quality non-magnifying red dot reflex sight designed to provide reliability and durability in a real-world situation.

Aimpoint PRO Red Dot Reflex sight is designed to military standards, but gun enthusiasts and hog hunters significantly favor it since it is friendly with night vision devices.

While compatible with most night vision devices, the Aimpoint Pro has 2 MOA dot and 6 daylight settings.

PRO battery life is quite reliable, with battery life measured in terms of years instead of hours.

The Aimpoint Pro reflex sight boasts 30,000 hours on power setting level 7 or 3 years.

This tube-style red dot sight features a rugged 30mm tube made of hard-anodized aluminum alloy. The Aimpoint PRO housing weighs only 7.8 ounces, but it has a water-resistant feature down to 150ft, and it can take some severe beatings because of its over-engineered build quality.


 10  Primary Arms SLX Gen III Prism Scope

We wanted to include one more Primary Arms scope on our list because they make so many models that work great for the .300 Blackout, and we hadn’t included a prism scope on our list yet.

The SLX Gen III prism scope has everything you need for your .300 Blackout. You can target long-range shots up to 600 yards, or you can stick to short and medium-range shots with this scope. The reticle is fully illuminated even in bright daylight conditions, so you don’t have to worry about losing sight of the reticle during your daytime hunts. 

It gives you up to 3” of eye relief when looking through the optical lens. When you need to zero your target and adjust for windage or elevation, just turn the turrets on the side or top of the scope to adjust ¼ MOA.

It’s made out of a durable type II hard-coat anodized black finish, making it shockproof, fogproof, and waterproof.

Primary Arms upgraded the mounting system on this scope. It now has greater strength and flexibility in the mount. Not only will it securely mount to your .300 Blackout, but it will also withstand the recoil during continuous firing during those times at the range or when you’re sighting in your scope.


 11  ATN ThOR 4 384 1.25-5x Thermal Smart H.D. Rifle Scope

The best thermal riflescope for the money and great entry-level thermal rifle scope comes from the ATN, one of the industry’s most prominent companies.

Unlike the older ThOR H.D. scopes, the Thor 4 series is powered by Obsidian IV Dual Core with a 60Hz refresh rate for long-range performance. The new integral computer in these upgraded devices enables higher thermal sensitivity and improved contrasts and resolution.
