CMMG Dissent MK4 6mm ARC 16.1" Side-Charging Rifle w/ Folding Stock

The CMMG Dissent MK4 delivers precision shooting performance in a compact, versatile platform chambered in 6mm ARC. This rifle combines CMMG's proven reliability with innovative features like side charging and a folding stock for enhanced portability and tactical flexibility.

What Makes This Different

The Dissent MK4 stands apart from traditional AR-15 platforms with its side-charging handle that eliminates interference with optics and allows for ambidextrous operation. The 6mm ARC chambering provides superior ballistic performance compared to 5.56 NATO, delivering flatter trajectories and better wind resistance for precision shooting at extended ranges. The integrated folding stock reduces overall length by 7 inches when folded, making transport and storage significantly more convenient than fixed-stock alternatives.

The rifle excels in precision shooting applications where accuracy and portability matter most. Competition shooters benefit from the stable platform and precise trigger control, while the folding stock makes it ideal for vehicle storage or confined spaces. The adjustable gas system ensures reliable cycling with both standard and subsonic ammunition, maintaining consistent performance across different shooting scenarios.
