Features to Consider


best 300 blackout pistol

AR pistol barrels are usually 6 to 10.5 inches long. And since the .300 AAC Blackout is tailored specially for short-barrel configurations, most of the factory ammo (check current prices at PSA) in this caliber burns powder efficiently within that range. 

But then there’s the matter of material construction and twist rate.

Subsonic loads have heavier bullets weighing 225 grains and above so they’ll perform better with 1:8 twist rate. Supersonic loads have lighter projectiles (85 to 125 grains) so a 1:7 twist rate will be more advantageous for bullet stability.

As for material construction, a high-quality .300 Blackout barrel is usually made from cold-hammer forged stainless steel that specializes in rust resistance or chromium-molybdenum alloys that are more durable because they’re heat-treated.


Your trigger plays a big role in getting the most accuracy out of your .300 Blackout pistol. Your trigger should break cleanly and not have any creep before it releases. After the release, your trigger should not have excessive backward movement or “overtravel.” Too much overtravel will have a negative effect on follow up shots for automatic actions. Adjustability is also a great pro on a trigger as it allows you to set your preferred pull weight.

Along with a clean and crisp trigger, smooth and user-friendly controls greatly contribute to a firearm’s reliability. Ambidextrous controls aren’t only helpful to lefties but are also useful for one-hand operation. 

Fit and Finish

A reliable pistol comes with a hard-anodized finish that helps prevent corrosion and rust. And, it’s well put together, with good matching between upper and lower and a secure mating of the barrel to the upper for the highest accuracy.

If you’re putting together an SBR, you’d need the best 300 Blackout SBR upper, too! And to further increase your accuracy, pair it with the best 300 Blackout red dot.


Price plays an important role in a consumer’s decision-making process. Like what we always tell our readers, if you’ve got money set aside for your gun or gun accessories, splurging on premium brands is best since you’ll likely keep and use them for a lifetime. But if your budget is limited, there are also a lot of budget-friendly but reliable pistols to choose from.

Rattler is hard not to love. Functions flawlessly, compact and incredibly versatile. Benelli m4, Sig p226 and Rattler are my go to kit for a reason.

All of our picks above offer convenience and portability while achieving the .300 AAC BLK’s full potential without the hassle of paying for an NFA tax stamp and submitting an ATF form. However, ATF is trying to roll out a new regulation that any AR pistol with an overall length under 26 inches and a barrel shorter than 16 inches will be considered as a short-barreled rifle.
