CMMG 28A490FCT Dissent MK4 16.1" 11-Round Cerakote Rifle

The CMMG 28A490FCT Dissent MK4 16.1" 11-round Cerakote rifle represents a modern, purpose-built platform for tactical shooters, law enforcement professionals, and serious civilian operators who demand reliability and modularity in a compact rifle system. This .45 ACP carbine fills a critical niche for those seeking soft-recoil ballistics in a rifle-length platform, making it ideal for training, home defense, or duty applications where manageable recoil and rapid target transitions are paramount. The 16.1-inch barrel length balances velocity retention with maneuverability in confined spaces—a proven formula in both military and law enforcement tactical operations.

Built on CMMG's modular Dissent platform, the MK4 variant features a full-length Picatinny rail system for unrestricted optic and accessory mounting, allowing operators to configure the rifle for specific mission requirements. The Cerakote finish provides superior corrosion and wear resistance compared to standard anodizing, critical for weapons exposed to moisture, salt environments, or frequent handling. The 11-round magazine capacity optimizes reload cycles while maintaining a compact footprint, and the lightweight 11.4-pound overall weight reduces shooter fatigue during extended operations without compromising controllability or structural integrity.

This rifle excels for shooters transitioning from pistol-caliber platforms or those building a .45 ACP ecosystem for ammunition commonality across multiple firearms. Law enforcement tactical teams benefit from the low-flash, low-recoil characteristics of the .45 ACP cartridge during close-quarters operations, while civilian operators value the soft-shooting ergonomics and reduced muzzle signature for home defense scenarios. The CMMG design philosophy prioritizes drop-in compatibility with standard AR-platform components, enabling end-users to swap uppers, charging handles, and furniture without gunsmith intervention—a practical advantage for operators maintaining multiple rifle configurations in the field.
