CMMG Dissent MK4 9mm Pistol 10.5" Barrel 33rd M-LOK Handguard

The CMMG Dissent MK4 represents a significant advancement in pistol-caliber carbine design, delivering AR-15 ergonomics with enhanced reliability through CMMG's proven radial delayed blowback system. This 9mm Luger platform eliminates the traditional buffer tube requirement while maintaining familiar controls and handling characteristics.

What Makes This Different

Unlike direct blowback systems that rely on heavy bolts and violent cycling, the Dissent MK4 employs CMMG's radial delayed blowback technology to reduce felt recoil and improve accuracy. The system operates 40% smoother than conventional blowback designs while accepting standard Glock magazines. The left-side charging handle provides ambidextrous operation without interfering with optics or charging during firing positions.

Key Features

• Radial delayed blowback system reduces recoil and improves reliability
• 10.5-inch barrel with Zeroed linear compensator for reduced muzzle blast
• 9.6-inch M-LOK handguard with full-length Picatinny top rail
• Left-side charging handle for ambidextrous operation
• Zeroed drop-in single-stage trigger with crisp 4.5-pound pull
• Accepts standard Glock 9mm magazines (33-round included)
• Picatinny brace adapter for SB Tactical and similar braces

The Dissent MK4 excels in competitive shooting environments where rapid follow-up shots and magazine changes matter most. Law enforcement agencies appreciate the familiar AR-15 manual of arms combined with reduced training ammunition costs. The linear compensator directs muzzle blast forward, making it suitable for indoor ranges and close-quarters applications where side blast concerns exist.
