While 5.56×45mm NATO has had widespread acceptance in military circles,[definition needed] the nature of the missions encountered by some special operations groups often demand a round that provides better performance than that available in the high-energy, standard velocity rounds, and subsonic performance greater than standard 9×19mm Parabellum (the ubiquitous pistol and submachine gun) round.
To meet this demand, AAC developed the .300 AAC Blackout in cooperation with Remington Defense. The new cartridge was intended to negate many of the perceived drawbacks inherent to other large caliber cartridges used in the M4. Colt Firearms and other arms makers had previously chambered AR-pattern rifles and carbines in various .30 caliber rounds but encountered problems. In the case of the 7.62×39mm, its relatively severe case angle caused feeding issues unless specially modified AK-47 magazines were used, and even then results were unsatisfactory. Modified bolts were also needed owing to its larger case head diameter. Rounds such as the 6.8 SPC and 6.5 Grendel had similar parts-interchangeability issues but did allow for the use of the standard M4/M16 30-round magazine, albeit with a reduced capacity.
