CMMG 60AA90CCT Dissent MK4 5.56 NATO 16.1" 11-Round Folding Stock Rifle

The CMMG 60AA90CCT Dissent MK4 6mm ARC 10+1 (2) 16.10", Coyote Tan Rec/15" M-Lok Handguard, Side Charging Handle, Black Side Folding Stock & Zeroed Grip, Muzzle Brake, 60/90 Ambi Safety, Adj. Gas Block delivers the ballistic advantages of a heavy-hitting short action cartridge in a platform that maintains AR-15 dimensions and weight. By chambering the 6mm Advanced Rifle Cartridge (ARC), this rifle provides a flat-shooting, low-recoil solution that significantly outperforms standard 5.56 NATO at distance. From a professional standpoint, this configuration is an ideal bridge for operators who require precision capabilities without the bulk of a traditional large-frame AR-10.

Technical reliability is anchored by the integrated adjustable gas block, allowing you to tune the dwell time and cyclic rate for specific duty loads or suppressed fire. The 16.10-inch barrel is shrouded by a 15-inch M-Lok handguard, providing ample mounting surface for clip-on thermals, lasers, or bipods. The side charging handle is a critical ergonomic upgrade, enabling the shooter to clear malfunctions or chamber a round while maintaining a consistent cheek weld and sight picture, which is essential during rapid-engagement scenarios.

Deployment versatility is a hallmark of the Dissent series. The black side-folding stock reduces the overall footprint for vehicle-borne operations or discreet transport, while the CMMG Zeroed grip and 60/90-degree ambidextrous safety ensure positive control under stress. The Coyote Tan receiver finish offers a durable, non-reflective coating suitable for varied environments. When you review the specifications, it is clear this rifle is built for those who demand long-range performance in a modular, highly portable package.

Whether you are looking to buy a dedicated precision tool for professional duty or competitive use, this MK4 Dissent provides the necessary features for high-stakes accuracy. Each unit ships with two 10-round magazines, ensuring you have the capacity and spares needed for immediate field use. The inclusion of a muzzle brake further assists in rapid follow-up shots by mitigating the already manageable recoil of the 6mm ARC cartridge.
