The CMMG 28A490FMB Dissent MK4 16.1" 11-round Cerakote rifle is a precision-engineered platform purpose-built for operators who demand reliability, modularity, and rapid deployment capability. This rifle bridges the gap between law enforcement duty weapons and competitive tactical systems, making it ideal for professional shooters, agency armories, and discerning civilian tacticians. The Dissent MK4 lineage represents CMMG's commitment to producing American-made firearms that prioritize function over trends, with a 16.1-inch barrel profile that balances velocity retention and maneuverability in confined environments.
Built on a mil-spec AR-15 platform, the rifle features a durable Cerakote finish that resists corrosion, salt spray, and harsh environmental contamination—critical for extended field deployment or duty carry. The 11-round capacity accommodates modern intermediate cartridge performance while maintaining quick reload mechanics under stress. At 11.6 pounds unloaded, the rifle delivers optimal control without inducing shooter fatigue during extended training or operational use, while the compact 39.6-inch overall length ensures ease of movement through doorways, vehicles, and tactical environments. CMMG's manufacturing tolerances and quality-control processes ensure consistent function across ammunition types and operating conditions.
Law enforcement agencies, military trainers, and civilian end-users benefit from the Dissent MK4's modular design and aftermarket ecosystem support, enabling optic mounting, accessory integration, and component upgrades without gunsmithing. The rifle's 16.1-inch barrel length complies with federal regulations and delivers optimal muzzle velocity for duty and training applications. Operators deploying this platform should ensure familiarity with AR-15 controls and maintenance protocols; the rifle accepts standard mil-spec magazines and components, maximizing supply-chain efficiency and operational interoperability across equipped teams.
