The CMMG Resolute 6mm ARC brings the 6mm ARC cartridge’s flat trajectory to a carbine platform, balancing compact handling with extended-range capability. It is suitable for precision target sessions, hunting where a lighter AR-style platform is preferred, and range-focused training.

Built on CMMG’s Mk4 architecture, the rifle integrates modern component choices and the ZEROED parts suite for consistent ergonomics and controls. The design includes a billet upper and forged lower, ambidextrous charging handle and controls, and a streamlined M-LOK handguard for accessory mounting.
