The 300 AAC Blackout also known as 7.62×35mm is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm cartridge, or even more similarly, the 7.92×33mm Kurz cartridge in an AR-15 while using standard AR-15 magazines at their normal capacities, it performs particularly well suppressed due to its typically subsonic nature.
