The CMMG Dissent Mk4 in .22 ARC (brand part no. 28A490FCT) is a next-generation, bufferless semi-automatic carbine built on CMMG’s Compact Action, packing 22-250-level performance into a platform with all the familiarity of an AR15’s manual of arms. CMMG pairs the 16.1-inch barrel with a 1:7-inch twist and a non-reciprocating forward side-charging handle, finishes the aluminum receiver in Coyote Tan Cerakote with a Picatinny top rail, and wraps the barrel in an M-LOK handguard. The rifle features CMMG’s DISSENT side-folding stock with adjustable length of pull and cheek riser, a ZEROED drop-in single-stage trigger, and a 60/90-degree ZEROED safety selector, shipping with two 10-round CMMG magazines. Among AR-platform rifles in the AR rifles category, the Dissent Mk4 favors shooters who want 22-250-level performance in a compact, familiar AR15-style build.
