CMMG Dissent MK4 .22 ARC 16.10in Upper Receiver, 6061-T6 Aluminum, M-LOK Rail 28B940CMB

Product Description The CMMG DISSENT MK4 upper group in .22 ARC (Advanced Rifle Cartridge) is built to add modern performance and flexibility to Mil-Spec compatible lower receivers. This 16.10-inch upper features a 6061-T6 aluminum receiver and an M-LOK handguard for lightweight strength and accessory-ready capability. CMMG&’;s patent-pending direct impingement Compact Action design keeps the action and recoil assembly within the upper receiver, helping reduce overall length and eliminate the need for a traditional buffer tube when used with the included 1913 Picatinny rear end plate. A forward, non-reciprocating side charging handle supports fast manipulation, while the adjustable gas block helps tune the system for suppressed use or different ammunition.
