CMMG Resolute Mk4 .22 ARC Rifle – 16.1″ Barrel, 10rd Magazine, Midnight Bronze Cerakote

The CMMG Resolute Mk4 in .22 ARC delivers a precision-engineered, feature-rich AR-platform rifle built for serious shooters who demand performance and durability. Chambered in the modern .22 ARC cartridge and finished in a striking Midnight Bronze Cerakote, this rifle combines cutting-edge materials with CMMG’s proven ZEROED component system for out-of-the-box readiness.

At its core, the Resolute Mk4 features a 16.1″ 4140 Chrome Moly Steel barrel with a 1:7 twist rate and Salt Bath Nitride (SBN) finish, paired with CMMG’s ZEROED Muzzle Brake on a 1/2×28 thread pattern. The direct impingement operating system is regulated by an adjustable 0.750″ gas block positioned at rifle-length, giving shooters precise tuning capability across a wide range of ammunition loads.

The upper receiver is machined from billet 6061-T6 aluminum, while the Mk4 lower receiver is forged from 7075-T6 aluminum for superior strength-to-weight performance. The 15″ CMMG EML M-LOK handguard provides ample real estate for accessories and keeps the profile slim and balanced. At just 6.4 lbs and 32.5″ in overall length, this rifle handles with the confidence of a full-size platform without unnecessary bulk.

CMMG’s ZEROED component suite rounds out the build with an ambidextrous charging handle, ambidextrous 60/90-degree safety selector, drop-in single-stage trigger, ZEROED pistol grip, and ZEROED trigger guard. The 6-position Fastback receiver extension with ambidextrous sling plate and CMMG RipStock complete a fully adjustable, ergonomic package ready for the range or field. Ships with a CMMG 10-round magazine.
