CMMG Dissent MK4 9mm

The CMMG Dissent MK4 is a 9mm AR-style pistol designed for modular performance on the range, in competition, and for defensive applications. It uses CMMG 9 AR conversion magazines to provide a familiar double-stack magazine profile and adaptable manual of arms.

Built with a Tungsten Gray receiver and a 5.50" M-LOK handguard, the Dissent MK4 emphasizes modularity and accessory compatibility. The pistol includes a Picatinny brace adapter, a left-side non-reciprocating charging handle, and a zeroed linear compensator paired with a drop-in single-stage trigger to offer a controllable, compact package. Its 9mm radial delayed blowback compact action uses a fixed ejector in the upper receiver and a lighter BCG for consistent performance across a range of 9mm loads.
