CMMG Dissent MK4 300 Blackout Pistol, 6.5"

The CMMG Dissent MK4: Portable Firepower Redefined

CMMG has engineered a revolutionary approach to the AR15 platform with the Dissent line of buffer-less pistols. This represents a significant departure from conventional designs, utilizing CMMG's patent-pending Compact Action to achieve unprecedented portability without sacrificing reliability or performance.

Key Features

• 6.5-inch free-floated barrel — Optimized for accuracy and velocity in the 300 Blackout cartridge
• 5.5-inch M-LOK handguard — Provides ample mounting surface for accessories while maintaining a compact profile
• Zeroed drop-in single-stage trigger — Factory-set for consistent performance out of the box
• Buffer-less design — Eliminates the traditional buffer tube, reducing overall length and improving ergonomics
• Coyote Tan Cerakote finish — Durable, professional-grade coating that resists corrosion
• 30-round capacity — Standard magazine compatibility with modern AR15 platforms

Why the Dissent Matters

The Dissent MK4 represents the shortest, most stowable personal defense weapon CMMG has produced. Its compact dimensions make it ideal for vehicle storage, home defense, or situations where space is at a premium. The 300 Blackout cartridge delivers effective power while remaining subsonic-capable for suppressed applications.

This is a purpose-built tool for those who understand that sometimes, smaller is smarter.
