The Combat Armory CA-15 300 Blackout pistol (brand part no. CA15.10SR.300P) is a complete AR-15 pistol built from billet 7075-T6 aluminum, with a 10.5-inch barrel, an M-LOK handguard and a pistol buffer tube. The receivers are hard-coat anodized black and every component is mil-spec. The 300 Blackout cartridge was designed to run well from short barrels, and 10.5 inches is long enough to give it a useful velocity boost over a 7.5-inch pistol. This listing is the standard 30-round configuration. For a shooter who wants a handy 300 BLK platform for suppressed or unsuppressed shooting, it is a straightforward starting point.
