The CMMG Dissent Mk4 in .22 ARC (CMMG part no. 28A490FCT) is a bufferless AR-pattern rifle with a 16.1-inch barrel and a Coyote Tan Cerakote finish. CMMG pairs the 22 ARC cartridge with its Compact Action direct impingement system and a forward non-reciprocating side charger, so the rifle carries AR controls in a shorter package. The DISSENT side-folding stock has adjustable length of pull and an adjustable cheek riser. It is for shooters who want 22-250 class performance in a compact, familiar rifle.
