CMMG Resolute MK4 22 ARC 16.1" 10+1 Semi-Auto Rifle

The CMMG Resolute MK4 pairs the company's adaptable Mk4 AR-15 platform with the modern 22 ARC cartridge in a full-size, semi-auto tactical rifle. Built for shooters who want full-size rifle handling without going to a pistol or SBR format, the Resolute MK4 ships as a complete, ready-to-scope rifle.

The 16.1" barrel is finished in black nitride, features a 1:7.5" twist, and is threaded for suppressor or compensator use. Up front, CMMG's Zeroed Muzzle Brake helps keep muzzle rise in check. The barrel is paired with an M-LOK handguard and a Coyote Tan Cerakote-finished Picatinny optics rail on top, giving plenty of real estate for an optic, light, or laser.

The upper and lower receivers are machined from aluminum and finished in Coyote Tan Cerakote, contrasting with the black nitride barrel assembly. The action runs semi-auto with a 10+1 capacity. Controls include an ambidextrous safety lever, the CMMG Zeroed Drop-In single-stage trigger, and CMMG's signature extended magazine release. The CMMG 6 Position RipStock provides adjustable length-of-pull, while a black polymer pistol grip rounds out the ergonomics.

Sights are not included, letting you mount your preferred optic on the Picatinny rail. The rifle measures 32.5" overall and weighs 6.4 lbs unloaded. Right-hand operation. If you're looking for a complete, ambidextrous-equipped AR-15 in 22 ARC for hunting, range work, or general-purpose use, the CMMG Resolute MK4 is a turn-key option straight out of the box.
