The CMMG DISSENT MK4 chambered in 6mm ARC delivers the ballistic performance typically associated with larger, traditional short-action cartridges within a compact AR-Platform. This 16.1-inch barreled rifle is engineered for precise shot placement across extended distances, providing a versatile solution for competitive engagements, precision hunting, and general range operations. The 6mm ARC cartridge facilitates a flat trajectory and optimized terminal performance, contingent on ammunition selection. The DISSENT MK4 maintains the familiar AR-15 manual of arms, integrating CMMG ZEROED components to ensure consistent and reliable operation. This design facilitates its application across diverse roles, from a dedicated precision system to a compact personal defense firearm.
Key Features
6mm ARC Caliber
Integrates advanced 6mm ARC ballistics within the standard AR-15 platform, delivering extended effective range and optimized energy transfer with reduced recoil impulse.
DISSENT Side Folding Stock
Optimizes weapon footprint for transport and concealed carry applications. This stock system incorporates an adjustable length of pull and an adjustable cheek riser, facilitating consistent and repeatable shooter interface for enhanced precision.
Non-Reciprocating Forward Charging Handle
Permits rapid and positive bolt manipulation without disrupting the shooter’s sight picture or requiring deviation from the firing position. This design mitigates potential interference with optics and enables expedient malfunction clearance.
M-LOK Handguard with Integrated Picatinny Rail
Provides a robust and modular interface for the secure attachment of auxiliary systems, including tactical illumination, laser designators, and direct-mount optics. The integrated Picatinny section at the 12 o’clock position ensures rigid optic mounting.
Adjustable Gas Block
Allows for precise modulation of the gas system’s operating pressure, essential for tuning cyclic rate to specific ammunition loads or for maintaining reliable function when integrating a sound suppressor. This optimizes system performance and component longevity.
