CMMG Resolute MK4 6mm ARC 16.1" 10+1 Semi-Auto Rifle - Coyote Tan

The CMMG Resolute MK4 in 6mm ARC is a purpose-built semi-auto AR-15 platform rifle designed for hunters and extended-range target shooters who want AR ergonomics with serious ballistic reach. The 6mm ARC was developed to deliver excellent performance from an AR-15 magazine, offering supersonic capability well beyond 1,000 yards when paired with the right bullets and optics.

At the heart of this rifle is a CMMG Mk4 aluminum receiver set finished in Coyote Tan Cerakote, paired with a 6-position CMMG RipStock and an M-LOK handguard for accessory mounting. The 16.10" medium-taper barrel is threaded to accept the included CMMG Zeroed muzzle brake and is cut with a 1:7.5" twist optimized for stabilizing 6mm ARC projectiles.

Controls come from the CMMG Zeroed line, including a Zeroed drop-in single-stage trigger, a Zeroed 60/90 degree safety selector, and the matching Zeroed trigger guard and pistol grip. Sights are none, leaving the upper optics-ready for the red dot, low-power variable, or magnified optic of your choice. The rifle ships with one CMMG 10-round magazine.

With an overall length of 32.50" and a weight of just 6.40 lbs, the Resolute MK4 balances well for both field carry and extended range sessions. Like every CMMG rifle, it is backed by the company lifetime quality guarantee.
