$1,203.74
The CMMG Dissent MK4 upper is a compact 5.56 NATO rifle built for shooters who need quick handling without sacrificing performance. Left-side charging handle, 10.50″ barrel, and M-LOK rail make this upper ideal for tactical work, home defense, or close-quarters shooting.
Description
Built on a 7075-T6 aluminum receiver in Armor Black, this CMMG upper delivers reliability with a purpose-built compact footprint. The 10.50″ barrel pairs with a CMMG Zeroed Blast Compensator to manage recoil in tight spaces, while the 9.60″ M-LOK handguard gives you plenty of real estate for mounting lights, lasers, or grips without excess length. The left-side charging handle keeps things ambidextrous, and the 1:7″ twist stabilizes a full range of 5.56 loads. This is an upper for serious shooters who value maneuverability—whether you’re running home defense drills, competition stages, or tactical training.
