UPC: 810097509641 MPN: unavailable

The CMMG Dissent MK4 in .300 AAC Blackout pairs a compact 10.50″ threaded barrel with a Cerakote finish and factory-installed TriggerTech AR-D trigger to deliver a purpose-built AR-style pistol configuration. This MK4 includes a Picatinny brace adapter, a 9.60″ M-LOK handguard, a left-side charging handle, a zeroed linear compensator, and an adjustable gas block to tune function for a range of .300 BLK loadings. The Dissent platform eliminates the traditional buffer system for a more compact overall length while remaining optics-ready for accessory mounting.
