CMMG Resolute MK4 338 ARC 16.1" 10+1 Semi-Auto Rifle - Armor Black

The CMMG Resolute MK4 brings CMMG's Mk4 AR-platform rifle line into the new .338 ARC cartridge. Built around an aluminum receiver and chambered with a 16.10" threaded barrel, this semi-automatic modern sporting rifle ships in the rugged Armor Black finish with a 10+1 capacity.

The barrel is 4140 chrome moly steel with a Nitride finish and a 1:8" twist to stabilize a wide range of .338 ARC bullet weights. It is threaded 5/8x24 and fitted with CMMG's ZEROED muzzle brake for recoil management. The carbine-length gas system feeds the action reliably, and a ZEROED single-stage trigger provides a clean break. Sights are not included, leaving the upper free for your preferred optic.

An adjustable buttstock lets you dial in length of pull, and the ZEROED pistol grip and controls are finished to match the rest of the rifle in Armor Black. Overall length is 37.30" with a weight of 6.20 lbs, making the Resolute MK4 a balanced and maneuverable rifle for hunting, range, or defensive use. Chambering the new .338 ARC round in a familiar AR-platform package, this rifle slots naturally alongside existing Mk4 components and magazines.
