The CMMG Dissent MK4: Modern 9mm Pistol Engineering

The CMMG Dissent MK4 represents a thoughtful approach to 9mm pistol design, leveraging the proven modularity of the AR platform while addressing the unique demands of 9mm ammunition.

Key Features

  • Radial Delayed Blowback Action: CMMG's proprietary compact action handles the full spectrum of 9mm loadings—from supersonic to subsonic—with consistent reliability
  • 33-Round Capacity: Uses standard CMMG 9mm AR conversion magazines with the familiar profile of 5.56mm magazines
  • Left-Side Charging Handle: Non-reciprocating design keeps you on target during operation
  • 6.5" Barrel: Optimized length for velocity and handling
  • M-LOK Handguard: Provides clean, modular accessory mounting
  • Picatinny Brace Adapter: 1913 rail end plate for slings, braces, or stocks
  • Zeroed Linear Compensator: Reduces muzzle rise and blast signature
  • Drop-In Single Stage Trigger: Smooth, predictable trigger break

Why This Matters

The fixed ejector design and lighter bolt carrier group reduce felt recoil while maintaining broad ammunition compatibility. Whether you're running standard pressure rounds or subsonic loads, the Dissent MK4 delivers consistent performance. The familiar AR manual of arms and true double-stack magazine feeding make this platform intuitive for shooters of any experience level.

This is a 9mm pistol built for shooters who demand reliability, modularity, and thoughtful engineering.
