Mfg Item #: BRN300BLKFMJ145
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.
We recommend using .300 Blackout magazines for optimum performance.
