Combat Armory CA-15 Pistol Features The Combat Armory CA-15 Pistol is built around a 7.5 4140 chrome moly vanadium barrel with an M4 feed ramp extension and a melonite finish for corrosion resistance under hard use. A 1:7 twist rate stabilizes a wide range of 5.56 loads from lightweight varmint rounds to heavier match bullets giving the shooter versatility across ammunition types. The pistol-length gas system paired with a low-profile .750 gas block keeps the action running reliably in the shorter pistol configuration while the 1/2x28 threaded muzzle accepts a flash hider brake or suppressor for further customization. A billet 7075-T6 upper and lower receiver both finished in Type III hardcoat anodizing provide the structural strength and wear resistance the platform is built around. The 7 M-LOK free float handguard keeps the slim profile needed for a compact pistol build while giving the shooter mounting points for lights foregrips or slings. A Picatinny top rail runs the length of the upper for mounting optics or iron sights and MIL-STD components throughout including the charging handle forward assist dust cover and fire control group ensure parts compatibility with the wider AR ecosystem. The pistol ships with one 30-round 5.56 magazine ready for the addition of an arm brace for a complete personal defense ready package. Combat Armory s billet construction and mil-spec parts make this a solid foundation for a maneuverable hard-use AR pistol build.
