The CMMG Dissent Mk4 in 6mm ARC (brand part no. 60AA90CCT) packs the long-range performance of .243 or .308 Win into a carbine that skips the weight of a larger AR-10-pattern rifle. CMMG pairs a 16.1-inch barrel with a 1:7.5-inch twist and an adjustable gas block for dialing in suppressed or unsuppressed use, and the rifle feeds from two included 10-round magazines. The Dissent side-folding stock adjusts for length of pull and cheek riser height, and a forward non-reciprocating charging handle allows manipulation without breaking your sight picture. A muzzle brake, an M-Lok handguard with a top Picatinny rail, and CMMG’s 60/90-degree ambidextrous safety round out the build, finished in Coyote Tan. Among modern sporting rifles in the AR rifles category, the Dissent Mk4 favors long-range shooters who want 6mm ARC performance in a folding-stock carbine.
