The CMMG Dissent MK4 300 Blackout combines proven AR-15 ergonomics with straight-blowback reliability in a compact platform. This 16.1-inch barrel configuration delivers optimal velocity for subsonic and supersonic 300 BLK ammunition while maintaining maneuverability for close-quarters applications.
What Makes This Different
Unlike traditional AR-15 platforms, the Dissent MK4 utilizes a straight-blowback operating system that eliminates gas system complexity. The radial delayed blowback action cycles reliably with both suppressed and unsuppressed fire, reducing maintenance requirements compared to direct impingement systems. The midnight bronze Cerakote finish provides superior corrosion resistance while maintaining a professional appearance.Key Features
