CMMG Resolute MK4 34A120FTNG | .338 ARC | 16.10″

The CMMG Resolute MK4 34A120FTNG is an AR-platform semi-automatic rifle chambered in .338 ARC with a 16.10-inch threaded Black Nitride barrel and a Tungsten Cerakote aluminum receiver. It pairs modern AR ergonomics — M-LOK handguard, Picatinny rail, and a CMMG Ripstock — with a large-bore cartridge designed for increased energy and reliable suppressed/unsuppressed transitions. This configuration is intended for shooters seeking a compact, versatile platform for medium-range work where the .338 ARC delivers more terminal energy than smaller AR cartridges.

Recommended optic: a variable 1-6x or 1-8x scope such as the Vortex Viper PST Gen II 1-6×24 provides a robust, sub-$1000 option that balances close-quarters speed and precision at extended ranges while remaining durable enough for field use.

Applications: medium-range hunting and precision target work at public or private ranges.
