Combat Armory CA-15 5.56 NATO 16" 10rd M-LOK Slim Rail Rifle

This is the rifle version of Combat Armory's AR-15, built on billet aluminum receivers with an anodized black finish and mil-spec components throughout. The 16" barrel is the shortest length that keeps a rifle clear of NFA paperwork, which is why the large majority of AR-15s sold in this country wear exactly that number.

The barrel is M4 profile under a Melonite finish, with M4 feed ramps in the extension and a carbine length gas system feeding it - the arrangement that has run in service rifles for decades and by far the easiest one to find replacement parts for. Threads at the muzzle are 1/2-28. A 15" slim M-LOK rail runs nearly the whole length of the barrel, which means a bipod, a light or a sling mount can go almost anywhere out front instead of being crowded onto four inches of handguard behind the gas block. The magazine included holds 10 rounds, so the rifle travels to capacity limited states without a parts swap. Combat Armory assembles the rifle complete, so it arrives as a working firearm rather than as a kit waiting on the last two parts.
