CMMG 28AB60CAB DISSENT MK4 22ARC 16.1 ARBLK

The CMMG DISSENT MK4 in 22 ARC is a purpose-built modern sporting rifle engineered for precision long-range performance in a lightweight, AR15-compatible platform. Chambered in 6mm ARC—a centerfire intermediate cartridge optimized for extended-range shooting—this rifle delivers flat trajectory and energy retention comparable to larger calibers like .243 Winchester or .308 Winchester, while maintaining the ergonomics and manual of arms familiar to AR15 operators and tactical professionals.

The 16.1-inch barrel balances velocity potential with overall carbine length, making the rifle suitable for both precision work and more mobile tactical scenarios. At 9.56 pounds, the CMMG DISSENT MK4 remains lighter than traditional AR-10 and LR-308 alternatives, reducing fatigue during extended field use or training sessions. The rifle features CMMG's DISSENT side-folding stock, enabling compact deployment from vehicles, aircraft, or storage configurations while maintaining user control and cheek weld consistency during fire. The platform accepts standard AR15 magazines and components, streamlining logistics and reducing training curve for operators already versed in AR manual of arms.

This configuration appeals to precision riflemen, designated marksmen, hunting professionals, and law enforcement specialists who prioritize accuracy and reach without carrying the weight penalty of larger-frame rifles. The 6mm ARC caliber also provides superior ballistic performance over 5.56 NATO at extended distances, making it a compelling choice for operators requiring legitimate long-range capability from a compact platform. The black finish and 41-inch overall length (folded configuration) suit both duty and training environments where discretion and transportability matter.
