Product Description

The .300 AAC Blackout cartridges were developed by Advanced Armament Corporation (AAC) for use in the M4 carbine to achieve ballistics similar to the 7.62x39mm supersonic cartridge, and to offer a subsonic yet powerful cartridge for the AR15 platform as an alternative to the MP5SD 9mm, all while utilizing a standard (STANAG) magazine.

The BarnauL .300 Blackout, available now, is a 145-grain supersonic cartridge with a polymer-coated steel case. This is the most affordable .300 Blackout ammunition on the market today.

A .300 Blackout subsonic cartridge is a heavy, lower-velocity round perfect for pairing with a suppressor. Using subsonic cartridges with a suppressor helps to eliminate the "crack" that is inherent with supersonic cartridges, reducing noise levels down to a safer volume.

(5 out of 5) Barnaul 300 AAC Blackout
by from Everett, WA on

Great target rounds. They work well in both a pistol and AR rifle. I was thinking I would have some hang ups but not a one. 50 yard and 100 yard placed well. I also used it to sight in, so after I got it sighted on both platforms, I was hitting very well
