CMMG Dissent MK4 6mm ARC 16.1" 10+1 Semi-Auto Rifle - Midnight Bronze

The CMMG Dissent MK4 is a semi-auto AR-platform rifle chambered in 6mm ARC, engineered around CMMG's Dissent platform with ambidextrous controls and a distinctive side-folding stock design. This configuration delivers hard-hitting intermediate-caliber performance in a maneuverable rifle finished in a striking Midnight Bronze color.

At the heart of the Dissent MK4 is a 16.1" threaded steel barrel with a 1:7.5" twist to stabilize a wide range of 6mm ARC bullet weights. The barrel is capped with CMMG's ZEROED muzzle brake for reduced recoil and flash. Up top, the DISSENT 7075 T6 aluminum upper is paired with a Mk4 forged 7075 T6 aluminum lower outfitted with CMMG's ambidextrous controls and the ZEROED 60/90 degree safety selector.

The trigger is CMMG's smooth ZEROED drop-in single-stage unit, and the rifle ships with no iron sights so the user can mount their preferred optic directly to the upper. The included CMMG Dissent side-folding stock allows the platform to collapse for transport, with an overall length range of 25.90" to 36.60" depending on stock position. With a 10+1 capacity, the Dissent MK4 in 6mm ARC is well-suited for hunting, defense applications, and recreational range use.
