The CMMG DISSENT MK4 is made to maximize portability and modularity, most notably thanks to CMMGs 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. At the rear of the lower receiver is a 1913 picatinny rail section for attaching the brace or stock* that fits you best. Includes two Magpul 300BLK 30rd PMAG.
