300 Blackout

.300 AAC Blackout is an intermediate cartridge developed in the United States by Advanced Armament Corporation for use in the M4 Carbine. The cartridge yields increased performance in shorter barrels and effective subsonic performance for suppressor use when compared to 5.56 NATO. .300 Blackout utilizes standard 5.56 NATO Magazines and components with exception of the barrel. .300 Blackout was intended to negate many of the drawbacks with other large calibers used in the M4. Colt and other arms companies had previously chambered AR-pattern rifles and carbines in various .30 caliber rounds but encountered problems.
