CMMG Dissent MK4 Features

The CMMG DISSENT is an AR Personal Defense Weapon like no other. Incorporating a variety of new features and technologies, each DISSENT is made to maximize portability and modularity, most notably thanks to CMMG’s patent-pending Compact Action that houses the entire recoil system in the upper receiver, eliminating the need for the buffer tube altogether.

Chambered in 300 BLK, this DISSENT packs .30 cal power in an ultra-compact package that offers AR15 ambi controls and our forward non-reciprocating side charger that can be switched for left or right-handed operation.
