The CMMG Dissent Mk4 in .22 ARC (brand part no. 28AB60CCG) packs the long-range performance of .243 or .308 Win without the weight of a larger AR-10/LR-308 rifle, built around a 16.1-inch barrel with a 1:7.5-inch twist and compatible with AR15-pattern controls. CMMG finishes the rifle in Chameleon Green and fits the DISSENT side-folding stock with an adjustable length of pull and cheek riser, along with a forward non-reciprocating charging handle for quick manipulation without breaking the sight picture. The M-LOK handguard carries a top Picatinny rail, and an adjustable gas block lets shooters dial in cycling for suppressed or unsuppressed use, running a 60/90-degree CMMG ZEROED safety selector and feeding from a 10-round magazine. Among AR-platform rifles in the AR rifles category, the Dissent Mk4 favors long-range shooters who want flat-shooting 6mm ARC-class performance in a distinctive finish.
