CMMG DISSENT MK4 .22 ARC 16.1 Carbine

The CMMG DISSENT MK4 .22 ARC 16.1 Carbine is a modern intermediate cartridge platform engineered for shooters who demand precision, efficiency, and low recoil in a compact fighting rifle. Chambered in .22 ARC—a proprietary CMMG cartridge optimized for accuracy and velocity out of short barrels—this carbine serves law enforcement trainers, sport shooters, and tactical professionals seeking a cost-effective alternative to 5.56 NATO without sacrificing terminal ballistics or practical range. The 16.1-inch barrel length balances maneuverability indoors and in vehicles with the velocity needed to maintain the .22 ARC's ballistic advantage at extended distances.

Built on the DISSENT platform, this carbine combines a free-floating barrel with a refined bolt carrier group to deliver sub-MOA accuracy potential—critical for precision work. The modular design accepts standard AR-15 ergonomic controls and furniture, allowing shooters to configure the platform to existing skill sets and training regimens. Weighing 10.3 pounds unloaded, the DISSENT MK4 provides a lightweight, handy profile (41.3 inches overall) suitable for rapid target acquisition and sustained fire. The .22 ARC cartridge generates minimal recoil impulse and muzzle rise compared to 5.56, enabling faster follow-up shots and reduced fatigue during extended training sessions or deployed operations.

Law enforcement academies, armorer training courses, and serious competitors benefit most from the DISSENT MK4's inherent accuracy and economical .22 ARC ammunition, which typically costs 30–40% less than comparable 5.56 loads while delivering superior barrel life. The modular AR platform design ensures compatibility with existing tactical accessories—rail systems, optic mounts, magazine pouches, and sling attachments. Installation of aftermarket components requires no gunsmithing; shooters can swap upper receivers, configure stock length, or add suppressors (with appropriate licensing) using standard tools and AR-pattern knowledge. This carbine represents a practical solution for precision rifle training, home defense staging, or precision hunting where ballistic efficiency and recoil management define the mission.
