CMMG Dissent .300 AAC Blackout

The CMMG Dissent is a compact AR-style pistol designed for personal defense, close-quarters use, and range work. Its patent-pending Compact Action places the recoil system in the upper receiver to eliminate the need for a buffer tube and improve portability. The Dissent ships with ambidextrous controls and a side charger that can be configured for either right- or left-handed operation.

Built for a compact footprint, the Dissent combines a short 6.50-inch barrel with a 5.5-inch M-LOK handguard and a Cerakote finish in Coyote Tan for corrosion resistance and subdued appearance. Ergonomics include an OEM polymer grip and a 1913 Picatinny rail end cap for attaching a brace or stock where permitted, while the included TriggerTech two-stage trigger provides a predictable interface.
