The CMMG Resolute Mk4 in .350 Legend (MPN 35A2C0AAB) is built on CMMG’s ultra-capable Mk4 AR-15 platform, chambered for a straight-walled hunting cartridge engineered by Winchester to deliver more power downrange with less recoil than .30-30 or .243 Win in states with cartridge restrictions. CMMG builds the 16.1-inch barrel from 4140 chrome-moly with a nitride finish and a 1:16-inch twist, threaded 1/2×28 for the CMMG ZEROED muzzle brake, running a non-adjustable 0.750 gas block. The rifle carries a billet 6061-T6 aluminum upper over a forged 7075-T6 Mk4 lower, ambidextrous charging handle and ZEROED pistol grip, a drop-in trigger, and the CMMG RipStock on a 6-position Fastback receiver extension. Among AR-platform rifles in the AR rifles category, the Resolute Mk4 favors deer hunters in straight-wall-cartridge states who want a carbine-length AR with less recoil than traditional hunting calibers.
