CMMG Resolute Mk4 6mm ARC

The CMMG Resolute Mk4 chambered in 6mm ARC is designed to extend the effective range of the AR15 platform while maintaining carbine-length handling. It is suitable for range work, precision target shooting, and field use where flatter trajectories from a smaller package are preferred.

The Mk4 is built around CMMG's ZEROED parts set and RipStock, and is finished in Cerakote Armor Black. Ergonomic controls, an ambidextrous charging handle and ambidextrous safety promote straightforward operation, while the EML15 M-LOK handguard allows accessory mounting without excess weight.
