CMMG 60AF30CTNG | Resolute MK4 6mm ARC | 16.1″ 10rd

The CMMG Resolute MK4 in 6mm ARC is an AR-platform modern sporting rifle built to extend the effective range of .223/5.56 platforms while maintaining AR-15 ergonomics. It features an EML handguard with full-length M-LOK slots, ambidextrous controls, a CMMG RipStock buttstock and a Cerakote Tungsten finish. The rifle ships with a 10‑round CMMG magazine and a 16.1″ barrel on a mid-length gas system.

For use with this rifle, a versatile optic under $1,000 such as the Vortex Viper PST Gen II 1-6×24 provides a robust, low‑power variable option suitable for both rapid target acquisition and moderate-distance precision work.

Applications: precision AR-style long-range shooting and varmint or medium‑game field use where flatter trajectories and higher ballistic coefficients are desired.
