Barnaul 300 Blackout 145Gr Full Metal Jacket 500 Round Case Ammunition

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.

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

A .300BLK 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.
