CMMG Dissent MK4 6mm ARC 16.1" Side-Charging Rifle Coyote Tan

The CMMG Dissent MK4 delivers precision long-range performance in the versatile 6mm ARC cartridge, combining innovative side-charging operation with a compact folding stock design. This rifle bridges the gap between traditional AR platforms and modern precision systems.

What Makes This Different

The Dissent MK4 features CMMG's proprietary side-charging handle system, eliminating the need for a traditional charging handle while maintaining full ambidextrous operation. The 6mm ARC chambering provides superior ballistic performance compared to 5.56 NATO, delivering flatter trajectory and higher retained energy at extended ranges. The integrated folding stock mechanism reduces overall length for transport and storage while maintaining structural integrity during firing.

The 6mm ARC cartridge excels in competitive shooting scenarios and hunting applications where precision matters beyond 300 yards. The adjustable gas system ensures reliable function with various ammunition weights while the M-LOK mounting system accommodates bipods, lights, and other accessories. Weather-resistant finishes on all metal components provide durability in adverse conditions.
