Combat Armory CA-15 AR-15 Rifle 5.56mm | 16″ Barrel | 15″ M-LOK Full Pic Rail

The Combat Armory CA-15 Complete AR-15 Rifle delivers mil-spec performance at an exceptional value — making it one of the best entry points into reliable semi-automatic rifle ownership available today. Built from billet 7075-T6 aluminum with a Type III hard-coat anodized finish on both upper and lower receivers, this rifle is engineered to withstand hard use while maintaining the tight tolerances serious shooters demand.

At the heart of the CA-15 is a 16″ 4140 Chrome Moly Vanadium barrel with a Melonite finish for superior corrosion and wear resistance. The M4 barrel profile features a 1/2×28 threaded muzzle topped with an A2 flash hider, a 1:7 twist rate optimized for stabilizing a wide range of 5.56mm/.223 projectiles, and M4 feed ramps for reliable feeding. A carbine-length gas system paired with a .750 low-profile gas block keeps the operating system smooth and consistent.

The 15″ free-float M-LOK full-length Picatinny rail handguard provides a slim, comfortable grip while offering maximum surface area for mounting lights, lasers, grips, and accessories along the full length of the rail. The upper receiver features a mil-spec forward assist and dust cover, while the lower is equipped with a mil-spec fire control group, an ambidextrous mil-spec-style safety selector, and a pistol buffer tube. Includes one 30-round 5.56mm magazine.
