The 300 Blackout cartridge reaches its potential even with shorter barrels, and this CMMG DISSENT MK4 proves it. Built around a 10.5 inch barrel, this carbine maximizes the performance of virtually any 300BLK loading while maintaining a compact, portable profile. Unlike conventional AR15 designs, it eliminates the buffer system entirely, contributing to its sleek footprint.
The rear features a 1913 picatinny rail end plate, giving you the flexibility to mount a folding pistol brace or stock that matches your preferences and aesthetic. Multiple Cerakote finishes mean your DISSENT will have a distinctive appearance.
300 BLK’s versatility shines with different loadings tailored to specific applications, including suppressed shooting. Each DISSENT includes an adjustable gas block that lets you tune the gas system to run optimally with either supersonic or subsonic ammunition. The TriggerTech AR-D trigger was co-developed with CMMG to be fully optimized for DISSENT firearms and upper receiver groups, delivering a 4 lb pull weight with a light, repeatable break. CMMG does not guarantee optimal DISSENT functionality with Mil-spec or other aftermarket triggers.
