The CMMG Dissent Mk4 pistol in .22 ARC with a Midnight Bronze Cerakote finish (brand part no. 28AB60CMB) pairs a 16.1-inch barrel with CMMG’s buffer-less Compact Action, giving the flat-shooting .22 ARC cartridge a long-barrel platform without the bulk of a full-size AR15. CMMG cuts the barrel at a 1-in-7.5 twist to stabilize the cartridge’s bullet weights, and an adjustable gas block lets shooters dial in the system for suppressed use or their preferred load. A forward, non-reciprocating charging handle keeps hands on target while cycling the action, and the M-LOK handguard with a top Picatinny rail leaves ample room for accessories. Among AR pistols chambered for a modern long-range cartridge, this Dissent configuration favors shooters who want reach without extra weight.
