Capable of closely duplicating the performance of a 7.62×39 in an AR 15 platform and using existing 5.56mm magazines and bolts, the 300 Blackout is a popular solution to the constant demand for a more powerful AR 15 cartridge. Found in single-shot handguns and rifles, short barrel tactical carbines, or more traditional AR style rifles, as well as military applications, 300 BLK may very well become the latest ubiquitous thirty-caliber round.

Because the 300 BLK is the next logical progression for the AR 15 style rifles, inevitably you will want optics–and not just any scope but the best scope for 300 Blackout rifles and pistols. There are a great many optics on the market today, but a few are ideal for 300 BLK rifles. Modern scopes are typically designed with bullet drop reticles that show the angle of drop for a given cartridge at various ranges, and so allow you to more correctly place your shot right on target by simply glancing at the reticle markings, and placing the correct one on your intended target. With the popularity of 300 BLK, many quality scopes are now calibrated for its use and are readily available.

The Ultimate 300 BLK Scope

Quick. Name a top end optic for the AR 15. Did you say Trijicon? Good. Because that’s what this is. While not cheap, it is the ultimate in rock solid performance for 300 BLK optics. Suitable for military, law enforcement, or those demanding days at the range, the Trijicon ACOG (see full specs) with a 300 BLK reticle will do the job. Featuring a proprietary tritium-illuminated, battery-free illuminated reticle, and ballistic drop compensator for all 300 BLK rounds, it just doesn’t get any better than this. Designed first and foremost for tactical and combat duties, the scope can also be used for less demanding roles, and know that while everything else might fail you, your optic won’t. This just might be the best 300 Blackout scope.

Trijicon ACOG What's the Big Deal?

A Reasonably Priced, More Traditional Scope

As much as we’d all enjoy it, sometimes the money for a Trijicon just isn’t there. But, for the dedicated 300 BLK shooter, there are still plenty of options for you to enjoy. The Nikon P-Tactical (see full specs) is a budget-friendly scope packed full of high-dollar features. Sporting a reticle calibrated for super and subsonic 300 BLK ammo and fast-adjusting spring-loaded turrets, Nikon’s famous multicoated optics, and built to work with Nikon ballistic software, the P-Tactical is the one of the best 300 Blackout scopes for the money. It is also ideal for a person desiring a more traditional looking rifle scope. The P-Tactical is at home both on top of a modern semi-automatic rifle and on a traditional bolt-action platform.

A LPVO Could Work

LPVO optics are all the rage these days and could make for one of the best scopes for .300 Blackout. What’s an LPVO? LVPO stands for low powered variable optic and it’s an optic that typically runs anywhere from 1 to 8 power magnification. They’ve become popular in the last 5 years for their versatility when it comes to both long range and short-range shooting. The Primary Arms LPVO in 1-6×24 is one of the more affordable but high-quality models out there. They produce a variety of these scopes and have designed one that coordinates with the .300 Blackout.

The ACSS reticle is perfect for both close range shootouts and longer range precision. The ACSS reticle is tuned to the 300 Blackout round and incorporates a bullet drop compensator that allows the end user to predict how the round will drop over a variety of distances. This optic sports an illuminated reticle, 12 brightness settings, and free lens covers.

Primary Arms SLxP3 3×32 Prism Scope

The Primary Arms SLxP3 prism scope is a poor man’s ACOG. What I mean is that like the ACOG, it’s a fixed power compact optic with a built-in bullet drop compensator. The Primary Arms Prism scopes, however, are still very well reputed and even well made.

The SLxP3 scope uses the versatile ACSS CQB reticle with its illuminated reticle that excels in both close range and moderate range shooting. The BDC is designed to be used with both supersonic and subsonic ammunition. The supersonic BDC goes out to 600 yards, and the subsonic goes all the way out to 225 yards. Both are within the realm of possibility of the 300 Blackout round. This optic gives you a more affordable optic in the ACOG’s realm of rule. For the money, this easily qualifies as the best scope for .300 Blackouts around.

Why You Need a 300 BLK Scope

With the performance improvement over 5.56mm, shooters have been building 300 BLK rifles in every configuration from heavy target or hunting rifles, to tricked out short barreled tactical carbines with advanced sound suppressors. Regardless of the application though, a high performing round like 300 BLK deserves a high performing optic to let you get the most possible benefit from your shooting time. Or, depending on the application, a good scope could mean the difference between bringing home a deer in the fall, or even saving somebody’s life. Sportsmen, competitive shooters, the military and law enforcement all have embraced 300 BLK, and no matter how you use it, there is a scope out there that matches your rifle’s job.  Good luck!
