The CMMG Dissent MK4: Modern Power in a Compact Package
The Dissent MK4 in 338 ARC represents a thoughtful evolution of the AR-15 platform, combining the ergonomic familiarity shooters know with the terminal performance of a true large-bore cartridge.
Why 338 ARC?
The 338 ARC cartridge was engineered to deliver what 300 Blackout promised: reliable subsonic and supersonic performance without constant gas system adjustments. The difference? More energy on target and less tuning headaches when switching between suppressed and unsuppressed fire.
Key Features
- 10.5" Black Nitride Threaded Barrel — Compact length ideal for close-quarters work while maintaining velocity; threaded for suppressor mounting
- 9.6" M-LOK Handguard — Modern rail system for mounting optics, lights, and accessories exactly where you need them
- Armor Cerakote Finish — Durable, corrosion-resistant coating on aluminum receiver for long-term reliability
- Picatinny Rails — Integrated top and rear rails for mounting optics and backup sights
- CMMG Zeroed Grip — Ergonomic design for positive control and reduced fatigue
- 338 ARC Compatibility — Uses the same bolt as 6.5 Grendel AR-15s, maximizing parts interchangeability
The Practical Advantage
This is a rifle built for shooters who want serious stopping power in a package that handles like an AR-15. Whether you're working suppressed or running full power loads, the 338 ARC delivers consistent performance without the constant tweaking required by other large-bore AR platforms.
