The CMMG 60AA90CSG Dissent MK4 6mm ARC is a purpose-built precision carbine engineered to deliver extended-range capability without the weight penalty of traditional AR-10/LR-308 platforms. Chambered in 6mm ARC, this rifle combines the ballistic efficiency of a dedicated long-range cartridge with the ergonomic familiarity and modularity of the AR-15 manual of arms—making it an ideal choice for operators seeking flat-shooting performance in a lightweight, handheld package.
The rifle is configured with a 16.10-inch barrel optimized for 6mm ARC velocity and accuracy, paired with a 15-inch M-Lok handguard that accommodates tactical accessory mounting while minimizing overall profile. The ambidextrous 60/90 safety provides intuitive operation for shooters of any hand orientation. A side-charging handle eliminates dust cover obstruction during operation, while the side-folding stock with adjustable geometry enables rapid transitions between shooting positions and compact storage. The zeroed grip and adjustable gas block allow fine-tuning for both suppressed and unsuppressed use, and the included muzzle brake manages recoil impulse. Supplied with two 10+1 capacity magazines, the platform delivers reliable feeding across extended shooting sessions.
This Dissent MK4 build serves precision shooters, long-range hunters, and tactical marksmen who demand sub-300-yard accuracy without compromising mobility. The 6mm ARC cartridge delivers superior ballistic coefficient and flatter trajectory than .223 Remington while maintaining reliable performance in intermediate-range engagements. At 11.6 pounds, the rifle remains handheld for extended periods—critical during unpredictable field deployment. The sniper gray receiver finish resists glint while maintaining corrosion resistance in variable conditions.
The Dissent platform has established itself as a practical middle ground between lightweight AR-15 carbines and heavier precision rifle systems. The 6mm ARC chambering specifically bridges the gap between intermediate-distance carbine work and true long-range shooting, making this configuration a strong choice for operators who need versatility without compromise.
