Overview
KFF Defense presents the CMMG Dissent MK4, a purpose-built 9mm Luger AR pistol engineered for compact performance and operational versatility. Leveraging the AR-15 platform’s inherent modularity, the Dissent MK4 integrates CMMG’s Radial Delayed Blowback Compact Action, optimizing performance across a broad spectrum of 9mm Luger ammunition loadings while mitigating felt recoil.
Key Features
Radial Delayed Blowback Compact Action
The Dissent MK4 utilizes CMMG’s proprietary Radial Delayed Blowback Compact Action, a significant technical advancement for the 9mm AR platform. This system addresses the operational challenges presented by the wide velocity and projectile weight variations of 9mm Luger ammunition, from subsonic to supersonic. By incorporating a fixed ejector within the upper receiver and a lighter bolt carrier group (BCG), the system consistently reduces felt recoil and enhances overall reliability. This design also maintains broad lower receiver compatibility, allowing for seamless integration with existing AR-15 lower receiver groups configured for 9mm.
Enhanced Ergonomics and Modularity
Operational efficiency is paramount with the Dissent MK4. A non-reciprocating, left-side charging handle facilitates rapid manipulation without breaking target acquisition. The 9.60-inch M-LOK handguard provides a robust interface for the direct attachment of lights, lasers, and other mission-essential accessories. The 1913 Picatinny rail end plate offers a secure and standardized mounting solution for pistol braces or slings, accommodating diverse operational requirements.
Optimized Feeding System
This Dissent MK4 is designed for compatibility with CMMG 9 AR Conversion magazines. These magazines are engineered to replicate the external profile of standard 5.56mm AR-15 magazines, ensuring a familiar manual of arms and seamless magazine pouch integration. Their true double-stack design guarantees reliable feeding and facilitates rapid, unobstructed loading.
Precision Trigger and Muzzle Device
The firearm integrates a CMMG Zeroed Drop-In Single Stage Trigger, providing a crisp, predictable break to enhance shot placement. Muzzle control is further managed by the included CMMG Zeroed Linear Compensator, designed to direct blast forward and mitigate muzzle rise, contributing to faster follow-up shots and improved shooter comfort.
