CMMG RSLT MK4 6MM ARC 16.1″ 10RD CT

Description

The Resolute Mk4 in 6mm ARC is built for shooters who want a capable mid-range precision platform in an AR-pattern carbine. The 6mm ARC was developed to deliver ballistic performance well beyond what standard intermediate cartridges offer at distance, with a projectile diameter that supports a wide selection of high-BC bullets suited to both hunting and precision rifle work. That combination makes this rifle a reasonable choice for deer-sized game, predator hunting, or longer-range target work where a standard-platform AR is preferred over a purpose-built bolt gun.

The 1:7.5″ twist rate sits between the faster twists optimized for heavier, longer 6mm match bullets and the slower twists better suited to lighter varmint loads. In practice it stabilizes bullets in the 103–108 grain range reliably, which covers most of the high-performance factory ammunition developed for the 6mm ARC. Handloaders working with heavier projectiles should confirm stability before committing to a load.

CMMG’s Zeroed safety offers both 60- and 90-degree throw positions, letting the shooter choose a shorter, more positive click if they prefer a modified grip angle without retrofitting a separate component. The rifle ships without sights, which keeps the setup cost honest for anyone already holding a preferred optic. The Coyote Tan Cerakote finish on this variant provides corrosion resistance in field conditions while keeping the profile consistent with earth-tone gear setups. The 10-round capacity reflects a specific configuration choice rather than the platform’s maximum potential.
