The CMMG 28AB60CMB DISSENT MK4 in 22 ARC is a purpose-built long-range carbine that delivers flat-shooting ballistics and extended effective range without the weight penalty of larger platform rifles. Built on the proven AR15 manual of arms and chambered in 6mm ARC—a modern intermediate cartridge optimized for extended-range precision—this 16.1-inch platform bridges the capability gap between standard rifle cartridges and traditional intermediate rounds. The forward non-reciprocating charging handle enables fast target transitions and manipulation in dynamic scenarios while maintaining shooter comfort during rapid sequences.
At 9.36 lbs, the DISSENT MK4 balances firepower with portability—critical for operators, sport shooters, and defenders who require extended-range capability without sacrificing mobility. The 6mm ARC cartridge delivers superior velocity and energy retention compared to 5.56 NATO, making it suitable for medium-range engagements beyond 300 yards. The 16.1-inch barrel is optimized for the 6mm ARC's ballistic profile, providing adequate velocity for consistent point-of-impact performance while maintaining an overall length compatible with tactical environments, vehicle operations, and tight quarters where full-length rifles prove unwieldy. CMMG's reputation for precision manufacturing and parts quality ensures reliability and accuracy out of the box.
The 6mm ARC DISSENT MK4 appeals to precision-focused shooters, designated marksmen, law enforcement specialists, and armed citizens who prioritize terminal performance and accuracy at distance. Those transitioning from AR15 platforms benefit from the familiar controls and ergonomics while gaining significant ballistic advantages. The 6mm ARC cartridge occupies a tactical niche: it delivers 243 Winchester or 308 Winchester performance characteristics using AR15-compatible receivers and magazines, eliminating the need to maintain separate platform training and logistics. Shooters evaluating long-range carbines, hunting rifles, or precision defensive systems will recognize the DISSENT MK4 as a practical, mission-ready option that doesn't compromise handling or weight for standoff capability.
