The CMMG Dissent MK4 is a compact AR-style pistol chambered in .338 ARC designed for portability and modularity. It uses CMMG’s patent-pending Compact Action to house the recoil system in the upper receiver, eliminating the need for a buffer tube. The platform pairs a 10.50-inch threaded black nitride barrel with a 9.60-inch M-LOK handguard for a compact footprint and accessory flexibility.
