Overview

The CMMG Dissent is a .300 AAC Blackout upper group featuring a 6.5-inch barrel and a 1:7 twist rate in an armor black finish. Utilizing CMMG's patent-pending Compact Action and radial delayed blowback technology with a fixed ejector, the entire action and recoil assembly is housed within the upper receiver to eliminate the need for a traditional buffer tube. It includes a forward non-reciprocating side-charging handle, an adjustable gas block for tuning supersonic or subsonic loads, an M-LOK rail, and a 1913 Picatinny rail end plate in place of a standard buffer tube.
