CMMG Dissent MK4 5.7 x 28 mm

The CMMG Dissent MK4 is a compact, buffer-less AR-style pistol chambered in 5.7 x 28 mm intended for short-range defensive use and range applications. Its patent-pending Compact Action reduces overall length while retaining familiar AR ergonomics and controls.

Built for portability and modularity, the Dissent MK4 pairs a free-floated 6.50-inch barrel with a short M-LOK handguard to keep weight and footprint low. The pistol is finished in black Cerakote and features an OEM black polymer grip, ambidextrous safety, and an optic-ready top rail for modern sighting setups.
