The CMMG Dissent Mk4 pistol in 9mm with a Midnight Bronze Cerakote finish (brand part no. 94A6867MB) uses the company’s 9mm Radial Delayed Blowback Compact Action, built around a fixed ejector in the upper receiver for a lighter bolt carrier and softer felt recoil. CMMG feeds the 6.5-inch barrel from CMMG 9 AR Conversion magazines, which share the same profile as 5.56mm mags for true double-stack feeding, and wraps it in a 5.5-inch M-LOK handguard. A forward, non-reciprocating side charging handle keeps hands on target while cycling the action, and a ZEROED drop-in single-stage trigger sharpens the pull. The rear Picatinny brace adapter plate takes the place of a buffer tube, ready for the shooter to add a brace separately. Among AR pistols built for extreme portability, this midnight bronze Dissent configuration favors shooters who want a true double-stack 9mm AR pistol.
