The next evolution of the AR15. Chambered in the iconic 5.56x45mm cartridge, the Cmmg Dissent Mk4 5.56mm 6.5" Pistol (55A938F) is unlike any other AR15 Personal Defense Weapon, ditching the buffer tube and traditional AR recoil system in favor of Cmmg's patent-pending Compact Action.
In addition to the revolutionary Compact Action that shrinks this AR pistol's footprint significantly, the Dissent features a forward non-reciprocating side charger that allows you to charge the weapon without coming off target.
Available in a variety of custom Cerakote finish options, the sleek sided rear of the Dissent features a 1913 picatinny rail that's ready to attach the brace or stock* that fits you best.
TriggerTech's AR-D trigger was developed in collaboration with CMMG to be fully optimized for use with Dissent firearms and upper receiver groups. With a 4 lb pull weight, the AR-D trigger showcases a light, repeatable break. Cmmg does not guarantee optimal Dissent functionality with Mil-spec or other aftermarket triggers.
