CMMG Dissent MK4 9mm Luger AR Pistol 10.5″ 33+1

The CMMG Dissent MK4 is a semi-automatic AR pistol chambered in 9mm Luger, configured with a 10.5-inch barrel and Midnight Bronze receiver. It features a left-side non-reciprocating charging handle, a 9.60-inch M-LOK handguard, and a Picatinny brace adapter for compatible accessories.

The platform uses CMMG 9 AR Conversion magazines with a profile matching 5.56mm magazines. Its 9mm Radial Delayed Blowback Compact Action uses a fixed ejector in the upper receiver, while the lighter bolt carrier group is designed to support consistent operation across a range of 9mm ammunition. The optic-ready configuration and ambidextrous safety provide a practical foundation for range use and accessory configuration.
