CMMG Dissent Mk4 Pistol, 5.7x28mm, 6.5-Inch, Coyote Tan

The CMMG Dissent Mk4 (CMMG part no. 54AA847-CT) brings 5.7x28mm to CMMG’s buffer-tube-free Dissent platform, giving shooters a flat-shooting, low-recoil personal-defense pistol in one of the most compact packages CMMG builds. A 6.5-inch barrel keeps the footprint tight, and the pistol ships with two 32-round magazines so you have a full reload ready from day one. A 5.5-inch M-LOK handguard keeps accessory mounting clean, and the TriggerTech AR-D trigger delivers a crisp break for a factory pistol. Finished in CMMG‘s coyote tan Cerakote, this Dissent is built for shooters who want serious capability without the bulk of a traditional buffer-tube AR pistol.
