CMMG Dissent MK4 5.7x28mm 6.5" 32-Round AR Pistol Midnight Bronze

The CMMG Dissent MK4 is an AR-style pistol chambered in 5.7x28mm, built on a direct impingement semi-automatic operating system with a 6.5-inch barrel finished in black nitride and a 1:9 twist rate suited to the 5.7x28mm cartridge. The 7075-T6 aluminum receiver carries a Midnight Bronze Cerakote finish, is optic-ready, and weighs 4.60 pounds with an overall length of 14.70 inches, making it a compact option for close-quarters and vehicle-based use.

The pistol has a 1/2x28 threaded compensator to help control recoil and muzzle rise, an M-LOK handguard for mounting lights, lasers, and grips, a Zeroed drop-in single-stage trigger, and ambidextrous safety controls. It ships with a black polymer grip and holds 32 rounds plus one in the chamber, with no sights included.
