The Combat Armory CA-15 Pistol, 5.56mm, 10.5-Inch, M-LOK (brand part no. CA15.10SR.556P) is a complete AR-platform pistol built from billet 7075-T6 aluminum receivers finished in hard-coat anodized black. Combat Armory chambers this pistol in 5.56mm with a 10.5-inch chrome moly vanadium barrel cut with a 1:7 twist, mated to a pistol-length gas system and a low-profile gas block under a 10-inch free-float M-LOK handguard. It ships with mil-spec fire control, safety, and charging handle components installed, and comes fitted with a pistol buffer tube rather than a stock or brace, keeping the pistol classification intact out of the box. Among AR pistols, this CA-15 favors shooters who want a mil-spec-component AR pistol built on a billet receiver set.
