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.
