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

The CMMG Dissent MK4 is a semi-automatic centerfire rifle chambered in 22 ARC, built around CMMG's compact-action DISSENT platform paired with the Mk4 lower receiver pattern. Shipped as a full rifle with a side-folding stock, it serves as a flat-shooting long-range carbine designed for precision shooting at extended ranges.

Up front sits a 16.10" threaded steel barrel finished in Black Nitride with a fast 1:7.50" twist that stabilizes a wide range of 22 ARC bullet weights. CMMG's compact DISSENT bolt cycles through an adjustable 0.750" gas block and feeds from a 10+1-round detachable magazine. A non-reciprocating charging handle keeps manipulation off-target, and the CMMG Zeroed muzzle brake tames felt recoil at the muzzle.

The DISSENT upper and the forged Mk4 lower are both built from 7075 T6 aluminum. The metalwork is coated in Midnight Bronze Cerakote, contrasted by black furniture for a clean two-tone look. A 15" M-LOK handguard with a full-length top Picatinny rail provides generous real estate for optics, lights, and accessories. No factory sights are installed, leaving the rail ready for your optic of choice.

Controls are fully ambidextrous via the CMMG Zeroed 60/90 degree safety, and the trigger is CMMG's Zeroed Drop-In single-stage design. The CMMG Dissent side-folding stock lets overall length collapse from 36.60" down to 25.90". The rifle weighs 7.70 lbs. Proudly made in the USA.
