The CMMG Dissent MkGs 9mm Pistol (brand part no. 99A660FAB) is a brace-equipped AR-pattern pistol, not a shoulder-stocked rifle, built around a 6.5-inch barrel for maximum portability. Fed by Glock-pattern magazines and cycling on CMMG’s Compact Action-Radial Delayed Blowback system, it stands as one of the most compact personal-defense pistols CMMG builds. Machined 7075-T6 aluminum upper and lower receivers wear a Cerakote finish for durability, and a forward, non-reciprocating side charging handle keeps the shooter’s eyes on target during manipulation. Every Dissent ships with a 1913 Picatinny rail end cap so the owner can mount a sling, brace, or other compatible accessory.
