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

The CMMG Resolute MK4 is a modern sporting rifle chambered in 22 ARC, built on CMMG's Mk4 platform with a direct impingement operating system. The 22 ARC cartridge pushes the AR-15 well past traditional carbine ranges, delivering 22-250-class ballistics in a compact, controllable package.

This rifle features a 16.1" threaded barrel in the MT contour with a 1:7.5" twist, paired with a CMMG Zeroed muzzle brake to keep recoil flat and the sight picture steady. The aluminum receiver wears a Midnight Bronze Cerakote finish, while the CMMG 6-position RipStock and black furniture round out a clean, duty-ready profile. Controls include an ambidextrous safety lever and a single-stage trigger.

Configured for 10+1 capacity with a standard AR-pattern detachable magazine, the Resolute MK4 ships without iron sights and is ready for your optic of choice. The rifle measures 32.50" overall and weighs 6.40 lbs, putting it right in the sweet spot for both range work and field carry. Made in the USA.
