CMMG Resolute MK4 338 ARC 16.10" 10+1 Semi-Auto Rifle - Tungsten Cerakote

The CMMG Resolute MK4 brings CMMG's large-bore AR-15 platform to life in 338 ARC, a cartridge designed to deliver serious stopping power from a familiar-pattern semi-auto rifle. This complete rifle pairs the proven manual of arms and modularity of the AR-15 with a 16.10" Black Nitride threaded barrel, an M-LOK handguard, and a Tungsten Cerakote aluminum receiver for a rugged, mission-ready build.

Chambered in 338 ARC, the Resolute MK4 cycles through a semi-auto action and feeds from an included detachable box magazine for a 10+1 capacity. The barrel carries a 1:8" twist and is finished in black nitride for long-term corrosion resistance, and is tipped with a CMMG linear compensator to tame muzzle blast and felt recoil at the shooter's ear.

The upper and lower receivers are machined from aluminum and finished in Tungsten Cerakote, with a full-length Picatinny rail up top for mounting an optic, red dot, or backup iron sight (sights not included). CMMG outfits the chassis with an M-LOK handguard for accessory mounting, the CMMG Ripstock in matching Tungsten polymer for adjustable length-of-pull control, and a CMMG Zeroed grip for an ergonomic, secure hold. Controls include the CMMG Zeroed 60/90 degree safety lever.

Built for shooters who want the modularity and handling of the AR-15 with the punch of a larger bore, the Resolute MK4 measures 37.30" overall and weighs 6.20 lbs unloaded, ready to add your favorite optic and head to the range.
