Description

CMMG Dissent MK4 Upper Features The CMMG Dissent MK4 Upper distinguishes itself with robust construction and advanced design. Its black-finished barrel comes equipped with a CMMG Zeroed Linear Compensator delivering reduced muzzle rise and enhanced control. A 9.60 M-LOK handguard finished in Armor Black offers plenty of real estate for mounting accessories and blends seamlessly with the rest of the unit. Made from 7075-T6 Aluminum the receiver guarantees durability and consistent function over time. The barrel sports a 1:7 twist rate ideal for stabilizing heavier bullets typical of the .300 AAC Blackout caliber. Both the receiver and the handguard are finished in Armor Black not only providing a unified aesthetic but also an added layer of protection against corrosion and wear.
