Combat Armory CA-15 5.56 AR Pistol 7.5″ Barrel 7″ M-LOK Rail

Description

The Combat Armory CA-15 is a complete AR-15 pistol built around a 7.5-inch barrel and chambered in 5.56mm. Both the upper and lower are machined from billet 7075-T6 aluminum and wear a Type III hard-coat anodized finish, so the whole platform is tough enough to take a beating while staying light and quick on target. This is a stubby, short-barreled build meant for close-in work where length and weight matter, and the pistol-length gas system is tuned to cycle reliably out of that shorter barrel.

What Makes the CA-15 Pistol Tick

The barrel is 4140 chrome moly vanadium steel with a Melonite finish, cut to an M4 profile with a 1:7 twist rate and M4 feed ramps. That 1:7 twist handles the heavier 5.56 and .223 loads most folks reach for, and the Melonite treatment adds corrosion resistance inside and out. The muzzle is threaded 1/2×28 and comes wearing a standard A2 flash hider, which keeps the setup simple and swap-friendly if you ever want to change muzzle devices down the road. A .750 low-profile gas block sits under the handguard and keeps the lines clean.

Handguard and Controls on the Combat Armory CA-15

Up front you get a 7-inch free-float handguard with a full-length Picatinny top rail and M-LOK slots around the rest, giving you a continuous sight plane plus plenty of room to mount lights, lasers, grips, or a hand stop wherever you like. The rest of the gun runs true MIL-STD parts: a MIL-STD charging handle, forward assist, dust cover, safety, and fire control group, all installed and ready to go. It rides on a pistol-length buffer tube.

If you're after a compact 5.56 platform that leans on familiar AR ergonomics and standard-spec internals, the CA-15 covers the bases without a lot of fuss. It feeds from standard AR magazines and ships with one 30-round mag to get you started.
