About this product

The CMMG DISSENT BR4 is a pistol-caliber carbine that combines traditional rifle ergonomics with CMMG’s radial delayed blowback design for the Mk4 DISSENT platform. Chambered in 9mm Luger, it accepts the 9mm conversion magazines and offers compatibility with other STANAG-pattern magazines when used with matching Mk4 DISSENT upper groups. Key hardware includes a 16.10″ Black Nitride threaded barrel, a Coyote Tan Cerakote aluminum Picatinny-rail receiver, a CMMG Zeroed muzzle brake, and a Magpul SGA black polymer stock.
