Description
The CMMG DISSENT upper group is a purpose-built 9mm AR-platform upper designed for compact pistol-style builds and short-barrel rifles when used in compliant configurations. This complete upper houses the action and recoil assembly in the receiver using CMMG’s Compact Action and Radial Delayed Blowback operating system, and it ships with a 1913 Picatinny rail end plate for use in place of a lower receiver buffer tube. The forward, non-reciprocating side charger is positioned for bolt manipulation without removing the upper from a shooting position. The unit is finished in Armor Black Cerakote and includes a CMMG ZEROED linear compensator and a 4.60″ M-LOK handguard.
