$1,203.74
The CMMG Dissent MK4 is a complete 5.7x28mm upper built for shooters wanting a compact, low-recoil AR platform that handles like a dream. Left-side charging handle, M-LOK handguard, and CMMG’s zeroed linear comp make this a purpose-built upper for tactical training or recreational shooting.
Description
Built on 7075-T6 aluminum receivers and finished in Armor Black, the CMMG Dissent MK4 delivers the 5.7x28mm’s inherent advantages—manageable recoil, minimal muzzle rise, and reliable performance—in a short 6.50″ barrel configuration. The left-side charging handle makes this upper equally at home for lefties or shooters who prefer alternative control setups, while the 4.60″ M-LOK handguard provides solid real estate for mounting lights, lasers, or other accessories. CMMG’s zeroed linear compensator tames what little recoil exists and directs gases downrange rather than up, keeping your sight picture clean during rapid fire. This is a serious choice for intermediate shooters building a dedicated 5.7 AR, whether for precision work at the range or dynamic shooting disciplines.
