The CMMG Dissent MK4: Compact Power Meets Modularity

The Dissent MK4 represents a significant departure from conventional AR platform design. CMMG's patent-pending Compact Action houses the entire recoil system within the upper receiver, eliminating the traditional buffer tube entirely. This innovation delivers genuine portability without sacrificing the ergonomics and controls shooters expect from an AR-pattern rifle.

Caliber and Performance

Chamber in 300 Blackout, this rifle delivers .30 caliber power in an exceptionally compact package. The 10.5" nitride-finished threaded barrel provides excellent velocity for subsonic and supersonic ammunition while maintaining a profile suitable for confined spaces, vehicles, and tactical applications.

Controls and Operation

  • Ambidextrous Controls: Full AR15-pattern controls accessible from both sides
  • Non-Reciprocating Side Charger: Switches between left and right-handed operation without tools
  • Forward Charging Handle: Keeps your support hand in firing position

Modularity and Customization

The 5.50" M-LOK handguard provides ample mounting real estate for optics, lights, and other accessories. A 1913 Picatinny rail section at the rear of the lower receiver accepts any standard brace or stock, allowing you to configure the rifle for your specific needs and local regulations.

What's Included

Two Magpul 300 Blackout 30-round PMags ensure you have adequate capacity for training or duty use. The rifle ships fully assembled and ready to shoot.
