CMMG Dissent MK4 10.5-inch 5.56 NATO Upper, Left Side Charging, M-LOK, Armor Black 55B8D86AB

Product Description

The CMMG DISSENT MK4 complete upper group is a compact 5.56x45mm NATO solution for AR-platform builders who want a streamlined, no-buffer style upper assembly. Built around CMMG's patent-pending Compact Action with a fixed ejector, the entire action and recoil assembly is housed in the upper receiver to reduce bulk and overall length compared to traditional AR configurations. A forward, non-reciprocating left-side charging handle enables fast manipulation while maintaining your sight picture. This upper features a 10.5-inch barrel, a 9.60-inch M-LOK handguard for accessory mounting, and a CMMG Zeroed Blast Comp at the muzzle. A 1913 Picatinny rear end plate is included for compatibility with 1913-mounted accessories in place of a buffer tube. Upper receiver only.
