CM15 5.56 Hog Rifle 16″ – Cobalt Kinetics Green Cerakote

Chattahoochee Munitions manufactures the CM15 5.56 Hog Rifle, a complete factory 16-inch 5.56 NATO AR15 in Cobalt Kinetics Green Cerakote with Coyote B5 Systems furniture, offered as a rifle with a B5 Systems Bravo stock. 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. It weighs 6 lb 8 oz with an unloaded magazine and ships with one 30-round ETS magazine.

A 16-Inch 5.56 Hog Rifle

Feral hogs are tough, often hunted in groups, and frequently shot at night where state law allows. The 5.56 Hog Rifle answers that with a 16-inch barrel that keeps full 5.56 velocity, light recoil for fast follow-up shots, and a 30-round magazine where legal. It is a rifle under federal law, so there is no NFA paperwork.

For hogs, use a 62 to 77 gr bonded or controlled-expansion bullet, keep shots inside about 150 to 200 yards and aim behind the shoulder; the 1:7 twist stabilizes those heavy bullets. The 15-inch M-LOK handguard takes a weapon light or thermal mount, and the Superlative Arms adjustable gas block tunes the cycle for a flow-through suppressor. If you want a shorter firearm for brush and vehicles, the 10.5-inch 5.56 SBR is the compact alternative. For heavier bullets with more energy on big boars, 6mm ARC and 6.5 Grendel CM15s are worth a look.

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.
