CMMG Dissent Mk4 Side-Folding 6mm ARC FDE/Tan Rifle

Description

Product Overview

The CMMG Dissent Mk4 is a compact 6mm ARC semi-automatic rifle built on CMMG’s AR-15-size Dissent platform. Its 16.1-inch 4140 steel barrel is threaded 5/8x24 and finished in Black Armor Cerakote, while the receiver features Midnight Bronze Cerakote. A side-folding stock with adjustable length of pull and cheek riser helps reduce storage length from 36.6 inches to 25.9 inches. The non-reciprocating forward charging handle, 15-inch M-LOK handguard, and top Picatinny rail support practical accessory and optic configuration. An adjustable gas block allows users to tune the direct-impingement system for different ammunition or suppressed use. The rifle includes a CMMG ZEROED muzzle brake, ZEROED drop-in single-stage trigger, ambidextrous 60/90-degree safety, and two magazines.
