The Combat Armory CA-15 5.56mm pistol (brand part no. CA15.10FR.556P10) is the same Mil-Spec AR-pattern build as Combat Armory’s standard CA-15 pistol, configured here with a compliant 10-round magazine for shooters who need to stay under a capacity restriction. The billet 7075-T6 aluminum upper and lower receivers are hard-coat anodized black, and the 10-inch, 4140 chrome-moly-vanadium barrel carries a melonite finish with M4 feed ramps for reliable feeding. A free-float M-LOK handguard runs the length of the barrel, and a carbine-length gas system with a low-profile gas block keeps the action cycling cleanly regardless of magazine capacity.
