The CMMG Dissent MkG .45 ACP rifle in Armor Black Cerakote (brand part no. 45ABE0FAB) is the bufferless take on the AR, built for shooters who want a compact, folding-stock .45 ACP rifle with a full 16.1-inch barrel. CMMG pairs the 16.1-inch barrel with a ZEROED RBB muzzle brake and 13-round magazines. The Dissent side-folding stock has adjustable length of pull and an adjustable cheek riser, and the forward side charger keeps your hands on target. Controls stay familiar: the ZEROED drop-in trigger, CMMG ZEROED pistol grip and a ZEROED 60/90-degree safety selector. Range work, truck-gun duty and general-purpose use all suit it.
