CMMG Dissent MK4 9mm Pistol | 10.50 in | 33+1

The CMMG DISSENT MK4 is a 9mm AR-pattern pistol built around modularity and modern PCC requirements. It ships with a 10.50-inch barrel, a 33 + 1 capacity using CMMG 9mm AR magazines, a 9.60-inch M-LOK handguard, and a left-side non-reciprocating charging handle. For a durable, purpose-fit optic under $1,000, the Vortex SPARC AR is a compact red-dot solution that pairs well with the platform’s sighting plane and workmanlike ergonomics.

This configuration suits pistol-caliber carbine (PCC) competition and range training, offering double-stack magazine capacity and a user-customizable accessory interface without altering the receiver geometry.
