Combat Armory CA-15 AR Pistol – 5.56mm | 7.5″ Barrel | 7″ M-LOK Full Picatinny Rail

The Combat Armory CA-15 AR Pistol delivers serious performance in a compact, maneuverable package — all at an impressive price point. Built on a billet 7075-T6 aluminum upper and lower receiver with Type III hard-coat anodizing, this pistol is engineered to mil-spec standards and ready to perform right out of the box.

At its core is a 7.5″ 4140 Chrome Moly Vanadium barrel finished in durable Melonite for superior corrosion and wear resistance. The M4-profile barrel features a 1:7 twist rate, M4 feed ramps, and a 1/2×28 threaded muzzle topped with an A2 flash hider — giving you flexibility for future muzzle device upgrades.

The pistol-length gas system pairs with a low-profile .750 gas block for reliable cycling, while the 7″ free-float M-LOK full Picatinny rail handguard keeps the platform lightweight and accessory-ready. Standard mil-spec components throughout — including the fire control group, charging handle, forward assist, dust cover, and safety — ensure dependable, familiar operation.

Ships with a 30-round 5.56mm magazine and configured with a pistol buffer tube, making it SBR-alternative compliant in most states (always verify local regulations).
