The CMMG DISSENT is an AR Personal Defense Weapon featuring a patent-pending Compact Action that houses the entire recoil system in the upper receiver, eliminating the need for a buffer tube. This design maximizes both portability and modularity in a single platform.
Chambered in 300 BLK, this DISSENT MK4 delivers .30 cal power in an ultra-compact 6.5″ configuration. The gun includes AR15 ambi controls and CMMG’s forward non-reciprocating side charger, which can be switched for left or right-handed operation to suit your preference.
The lower receiver features a 1913 picatinny rail section at the rear, and the weapon ships with a 30-round capacity magazine. The DISSENT is engineered for shooters who demand a compact, modular platform without sacrificing control or power.
