CMMG Resolute Mk4 300 BLK | 14.5in Pinned (16.1in) | 30rd

The CMMG Resolute Mk4 is chambered in 300 BLK and features a 14.5″ barrel fitted with a ZEROED SVD brake that is pinned and welded, producing an overall barrel length of 16.1″ for compliance while maintaining a compact carbine profile. The rifle is built on CMMG’s Mk4 AR-15 platform and is fitted with an EML15 handguard, RIPSTOCK, and a Magpul 30rd PMAG. For an optic under $1,000 that pairs well with this configuration, consider a 1-6x variable such as the Vortex Strike Eagle 1-6×24 for fast target acquisition and low-power precision.

This carbine-length configuration is well suited to suppressed subsonic shooting and short- to medium-range carbine work, including close-quarters training and suppressed range sessions using subsonic loads.
