CMMG Dissent MK4 300 Blackout 6.5" Pistol 30rd Coyote Tan

The CMMG Dissent MK4 brings AR-15 performance to a compact pistol platform, delivering 300 Blackout power in a package that measures just 6.5 inches. This radial delayed blowback system eliminates the need for a buffer tube while maintaining reliable cycling across subsonic and supersonic ammunition.

What Makes This Different

The Dissent MK4 uses CMMG's proven radial delayed blowback system instead of traditional direct impingement, resulting in a 20% reduction in felt recoil and significantly less gas blowback. The system operates without a buffer tube, allowing for true folding stock compatibility and more compact storage. Unlike straight blowback pistols that require heavy bolts, this design maintains proper timing with lighter reciprocating mass.

Key Features

• Radial delayed blowback system reduces recoil and eliminates buffer tube requirement
• 6.5-inch barrel optimized for 300 Blackout ballistics with 1:7 twist rate
• Coyote Tan Cerakote finish provides corrosion resistance and reduced signature
• Picatinny buffer adapter enables standard AR stocks and braces
• Zeroed single-stage trigger with 4.5-6 pound pull weight
• Standard AR-15 magazine compatibility accepts all STANAG magazines
• Mil-spec charging handle and safety selector for familiar operation

The 300 Blackout chambering excels in short barrels, maintaining effective performance for both hunting and tactical applications. Subsonic loads cycle reliably for suppressed use, while supersonic rounds deliver flat trajectories out to 200 yards. The radial delayed system handles both load types without adjustment, making it suitable for users who switch between ammunition types frequently.
