Description

The CMMG Dissent MK57 is a pistol-format firearm built around CMMG’s Radial Delayed Blowback operating system, chambered in 5.7×28mm — a high-velocity, low-recoil cartridge originally developed for personal defense and military applications. The 5.7×28mm chambering offers a flat trajectory and high magazine capacity relative to traditional pistol calibers, making the Dissent MK57 a firearm suitable for range use and home defense applications where round count and recoil management are relevant criteria.

The Dissent line is designed around an AR-pattern control layout, giving shooters familiar with the AR-15 platform a recognizable manual of arms. The 6.5″ barrel provides a balance between compactness and velocity retention for the 5.7×28mm cartridge. The Coyote Tan finish ties the firearm into common earth-tone gear and equipment color schemes. This pistol ships to a licensed FFL dealer for transfer in accordance with federal, state, and local law.
