CMMG Dissent MKGS 9mm Pistol | 10.50″ Barrel | 33+1

The CMMG DISSENT MKGS is a compact, pistol-caliber AR-style platform chambered in 9mm that combines a short 10.50″ barrel with a high-capacity magazine option for close-range work. Built on 7075 T6 aluminum receivers with a 5.50″ M-LOK handguard and a 1913 Picatinny rail end cap, the DISSENT is engineered for portability and accessory compatibility. It uses CMMG’s radial delayed blowback compact action and a left-side non-reciprocating charger for a lighter BCG and consistent performance across a range of 9mm loads. Pair this pistol with a red-dot like the Vortex SPARC AR for fast target acquisition without exceeding a $1,000 budget.

Typical applications for this platform include pistol-caliber carbine (PCC) competition and short-range range training or recreational shooting.
