How to find the best 300 blackout rifle scope

If you’re in a hurry, then here’s the list of the best scopes for the 300 Blackout:

What Are the Basics of a 300 BLK? – What is the 300 Blackout used for?

The 300 Blackout cartridge was developed by the U.S. Advanced Armament Corporation and succeeds the NATO 5.56 mm cartridge. It’s a harder-hitting cartridge with improved velocity performance, good for tactical use at moderate ranges.

The 300 Blackout uses the M4 assault rifle (have a look at the best-rated riflescopes for M4 rifles) as its platform and is intended for military use like the Steiner precision riflescopes. It’s virtually noiseless and makes for a great hunting rifle that is more versatile than its counterparts.

The 300 Blackout is a specialty cartridge that is approved in many state hunting regulations. It might not be the most powerful, but it’s quiet and effective at close range.

With silent subsonic high-velocity ammunition, it’s great for hunting small game. It does take some getting used to, which is why a good-quality scope can help.

When looking for a scope for a 300 Blackout, look at things such as recoil, overall range, and glass quality. Keep in mind that the 300 Blackout still underperforms compared to larger calibers in its range, but it does preserve barrel life with its lower powder charge.

Based on the range that you use the 300 Blackout, you will need to pay attention to glass quality so you can get crisper images. Light transmission and field of view (FoV) will allow you to get a clearer look at your target, but not all scopes are created equally!

This guide will help you narrow down your options by looking at different scopes for 300 Blackout. We tried to incorporate high-quality optics for different budgets and uses.

What Magnification Do You Need for Typical Use of a 300 BLK?

Typical uses for the best 300 Blackout scope call for magnification between 3x and 12x, although smaller targets will require higher magnification. The downside of this is a smaller visible area, which can limit how well you see your surroundings.

Low magnification calls for a 24 mm or 32 mm diameter lens and allows for faster targeting and larger FoV. That being said, there’s no reason why you couldn’t go for any of the scopes for 300 Blackout with a larger front lens and scope tube.

Typically, a larger tube and lens allow an increased amount of light into the scope. This can be helpful when you use your setup in low-lighting conditions to get a good target image. The downside certainly is that those scopes are heavier and will increase the weight of your setup when you carry it around.

Based on range, glass quality will differ, as shorter distances grant you better images than larger distances. That being said, longer distances have the advantage of elevation and windage.

Long-Range Shooting with a 300 BLK

Long-range shooting is anything over 300 yards and requires 9x to 12x magnification. The disadvantage is that it doesn’t achieve much penetration at this range.

Medium-range use is for shooting between 150 and 300 yards. It requires 5x to 9x magnification and works well for mid-size game. Shorter distances are under 150 yards and require 1x to 4x magnification.

This is suitable for small game. The 300 BLK scopes are meant for close and medium-range shooting and, therefore, should be capable of honing in at 20 to 300 yards without diminishing accuracy.

When looking for a 300 Blackout scope, pay attention to strength and reliability. Hunting will expose your rifle to lots of dirt and grime, plus a variety of weather conditions.

Consider the Ruggedness of the Scope

You need something that can stand up to this wear and tear – Cerakote your scope for more protection. Water and dirt can impede sight settings, and your scope could get jostled around if you hit a hard object.

Lens quality is important too when looking at the top scopes for the 300 Blackout, so look for multi-coated glass that can use light efficiently and stand up to weather conditions.

Keep in mind that brand name isn’t the whole story, as a more affordable scope could be just as good quality. The best 300 Blackout scope just needs to match what you’re going to use it for, so don’t be swayed by fancy names.

Finally, remember that the reticle any of the scopes for 300 Blackout should be easy to view and uncluttered, and the eye relief should ideally be over 3.5 inches. Typically, the lower the magnification, the longer the eye relief and the better the visible field.

Nikon P-300 BDC 2-7x32mm – Best Overall Scope for 300 Blackout

The Nikon P-300 BDC 2-7x32mm Riflescope is the overall best rifle scope for 300 Blackout. It’s got a basic design, but that’s what makes it versatile for use on many different rifles.

This Nikon scope weighs in at one pound and measures 11.5 inches long. Designed for M- and P-series mounts, it’s great for long-range shooting, and its double O-ring makes it a high performer in water and fog.

The Nikon P-300 scope has fully multicoated lenses (like all Nikon scopes) and provides maximum brightness while dispersing 98% of transmitted light. The ballistic calibrated BDC reticle is good for longer distances, as well as subsonic and supersonic ammunition.

Its 32 mm lens size is calibrated to shoot up to 600 yards. It’s capable of 2x to 7x magnification, so it’s best for larger targets.

This Nikon P-Tactical scope has a 3.7-inch eye relief and works well when your rifle has a bit of recoil. It’s not the best in challenging light conditions and there is no parallax adjustment option, but it has got an affordable price.

The spring-loaded turrets make for easier, sightless dialing, but they are a bit cumbersome.

That being said, they’re quite accessible when wearing loads of gear, so perhaps the large size is a good thing. The turrets have automatic zero reset and audible dialing adjustments for ease of use.

Overall, this Nikon scope transmits decent light for greater visibility and produces HD quality clarity. The reticle has open circle aiming points, elevated windage, and additional hash marks at interim distances. It is located on the second focal plane.

The P-300 is made of polymer and aluminum. It’s sturdy and won’t let you down on hunting trips.


  • Fully multi-coated lenses
  • HD-quality clarity
  • Spring-loaded, zero-reset turrets


  • No parallax adjustment option
  • Not the best in light that’s not bright

This scope is durable, but it’s also heavy at around 1½ pounds. That being said, all of its combined features may be enough to sway your opinion when you look for a scope for the 300 Blackout.

This includes first and second focal planes, lockdown zero-system turrets, and several illumination settings. Its night vision capabilities, as well as the Hellfire Fiber Optic and a glass-etched reticle that is illuminated, make for easier low-light shooting. A 3.8-inch eye relief adds extra comfort.

The Sig Sauer Tango6 allows you to shoot with both eyes open on 1x magnification. Meanwhile, the 6x magnification is good for medium-range shots.

This scope for 300 Blackout offers great precision and MOA adjustments, and its MRAD milling reticle has a field of view of 107 feet at 100 yards. It makes lining up a target smooth and easy. An innovative rotation counter makes long-range shooting a breeze.

Vortex Optics Crossfire II 2-7 x 32 mm – Best Affordable Scope for 300 Blackout

Check our review of the Strike Eagle riflescopes from Vortex!

The Vortex Crossfire 2 is waterproof and fog-proof, making it an awesome scope to have on hand in bad weather or the early morning hours. Image focus and parallax removal make it a bit overpowered for daytime shooting.

That being said, this scope offers superior light transmission and longer eye relief for more efficient targeting. The fast-focus eyepiece makes targeting even easier, so overall, this is a good budget choice.

While the light transmission isn’t great in low-light environments, the glass is very clear for low magnification. Things get muddled on 6x to 7x magnification, and the non-illuminated BDC reticle doesn’t help.

Even so, the lenses are multi-coated and anti-reflective for brighter, clearer views.

Given the price, this scope’s glass won’t be as high quality as others, but it offers a wide visible field, which is great for observing surroundings and acquiring a target. It also comes with a BDC reticle although it isn’t calibrated to the 300 Blackout. The reticle is positioned on the second focal plane.

The turrets are finger adjustable (so not as precise), but they are zero resettable and capped. The maximum elevation adjustment is 60 MOA, making this a decent scope for various distances.

Overall, this scope is well made. It is constructed out of hard-anodized aircraft-grade aluminum. It weighs in at 13.6 ounces, so it can be considered a mid-weight scope.


  • Fast focus eyepiece
  • Generous eye relief and narrow eye box
  • Wide visible field


  • Not well suited to daytime shooting
  • Turrets aren’t as precise as competitors

Leupold VX-R Patrol 1.25-4 x 20 mm – Best Lightweight 300 BLK Scope

The Leupold VX-R Patrol is a bit on the expensive side. The quality is there though, thanks to aircraft-grade aluminum, a 3:1 zoom ratio, and twilight light management settings. This makes it a decent choice in all kinds of light and weather conditions.

The magnification range goes up to 4x and there are windage and elevation adjustments as well. It’s worth noting that this scope’s 1x magnification isn’t true 1x, but 1.25x, which creates a slight fishbowl effect. – Have a look at what magnification you need for AR 15’s!

On the downside, this scope has exposed knobs, which could get in the way or just be burdensome while trying to focus. Moreover, the thicker reticle decreases the field of view a bit.

Even so, the lenses are pretty good, transmitting light well and holding up to scratches, water, and fog. This scope is also shockproof, which comes in handy when scouting through the brush.

This 300 Blackout scope is lightweight compared to its competitors, weighing in at 11.5 ounces. It is easy to use and fits well into the 300 Blackout. The magnification doesn’t get too intense, but it gets most jobs done.

The illuminated FireDot SPR reticle is great for low-light shooting, and the clear glass ensures good views. The motion sensor technology deactivates the illumination after five minutes of inactivity, helping to preserve the battery life.

Finally, the 30 mm main tube allows for extra strength and increased windage and elevation range.


  • Illuminated FireDot SPR reticle
  • Motion sensor technology
  • Sturdy and durable


  • Exposed knobs
  • Thicker reticle decreases sight
