It has a CrMV black nitrided 1:7 twist barrel threaded 1/2×28, a midlength gas system with a Superlative Arms adjustable gas block, an Odin adjustable buffer, a TriggerTech Duty trigger, ambidextrous controls and 7075-T6 billet receivers.

A 5.56 AR15 Rifle for Every Job

The 5.56 AR15 Rifle is a natural first CM15: a 16-inch, midlength 5.56 NATO AR15 for low-cost target shooting and training, with the same receivers, trigger and controls as the CM15s in larger cartridges. It also handles home and property defense, and predator and hog hunting. It is a rifle under federal law, so there is no NFA paperwork.

Because every CM15 shares the same receivers, controls, trigger, gas block and 1:7 barrel, this 5.56 AR15 Rifle differs from its siblings only in finish: FDE Metallic Cerakote with Coyote B5 Systems furniture. Optics mount on the full-length Picatinny top rail, and the 15-inch M-LOK handguard takes lights, slings and bipods.

5.56 NATO and .223 Remington Ammunition

5.56 NATO is a low-cost target and training round, which makes this CM15 a natural place to start. When you want heavier bullets or subsonic performance, the same platform steps up to 300 Blackout, 6.5 Grendel, 6mm ARC, 350 and 400 Legend and 338 ARC. This CM15 has a 5.56 NATO chamber, so it fires both 5.56 and .223 Remington. Never fire 5.56 in a firearm marked only .223 Remington. The 1:7 twist stabilizes 55 to 77 gr bullets. Read 5.56 vs 223, 5.56 twist rate and 5.56 ballistics.

Suppressor

The CM15 is gas operated and 5.56 NATO is supersonic, so Chattahoochee Munitions recommends a flow-through suppressor to limit back pressure. See 5.56 suppressor.

Other Lengths and Finishes

The same CM15 in other finishes: 5.56 NATO Rifle, 5.56 Hog Rifle. Other lengths: 5.56 SBR, 5.56 PDW. Complete uppers: 5.56 Pistol Upper, 5.56 NATO Upper, 5.56 AR15 Upper. See the full lineup at Garrison 5.56 and the CM15 5.56 NATO category.
