CMMG Dissent 9mm 6.5" Upper Group

The CMMG Dissent 9mm upper group puts the whole action and recoil system inside the upper receiver, using CMMG's Compact Action and Radial Delayed Blowback. Since nothing runs back into a buffer tube, it comes with a 1913 Picatinny rail end plate that replaces the buffer tube on your lower. The result is a shorter, trimmer AR pistol.

It fits Mk4 and standard AR-15 lower receivers when you run CMMG 9AR conversion magazines, plus CMMG MkG and Mk17 lower groups. The 6.5" barrel has a 1:10 twist and 1/2-28 threads wearing a ZEROED linear compensator, and a forward, non-reciprocating side charger on the left lets you work the bolt without breaking your hold. Cerakote finish.
