CMMG Dissent Mk3 33A380C-CT | 8.6 Blackout | 12.5″

The CMMG Dissent Mk3 (MFG# 33A380C-CT) is a semi-automatic pistol chambered in 8.6 Blackout with a 12.5″ Black Nitride threaded barrel and a 20+1 capacity. It pairs a coyote tan Cerakote aluminum receiver and Picatinny rail with an M-LOK handguard and a black polymer SB Tactical folding brace for a compact, suppressor-ready package. For optical pairing, a compact red-dot such as the Holosun 407C offers a robust, sub-$1000 option for fast target acquisition and close-to-medium range use. Practical applications include precision suppressed short-barrel work and range training/plinking.
