CMMG Resolute Mk4 Rifle 300 Blk

The CMMG Resolute Mk4 is designed as a carbine-length AR platform for shooters who want 300 BLK performance in a compact rifle-length configuration. It is appropriate for range training, tactical drills, and field use where a shorter, maneuverable rifle is preferred.

Built with CMMG’s components and ergonomic features, the Resolute Mk4 balances function and control. The EML-15 handguard reduces weight while providing M-LOK attachment points at common positions, and the rifle is finished in a Midnight Bronze tone for a refined appearance. The system includes CMMG’s RIPSTOCK for adjustable ergonomics and ships with a magazine for extended capacity.
