CMMG RESOLUTE MK4 | 6.5 Grendel | 16.1 in

The CMMG RESOLUTE Mk4 in 6.5 Grendel is a carbine-length AR platform rifle built for efficient medium- to long-range performance. It pairs a 16.1-inch 416SS SBN barrel with a 1:8 twist and a suite of CMMG ZEROED components for functional ergonomics. For an optic under $1,000 that complements this platform, consider a Vortex Viper PST Gen II 1-6×24 for fast, repeatable engagements at varied distances.

Suitable applications include precise target shooting at extended ranges and medium-game field use where a compact AR platform with improved ballistic performance is desired.
