CMMG Resolute MK4 22 ARC | 16.1 in | 28A670CAB

The CMMG Resolute MK4 is a carbine-length AR-platform rifle built for straight-line accuracy and controllable shooting with .22 ARC ballistic performance. It ships with CMMG ZEROED components and the RipStock, and features a lightweight EML15 M-LOK handguard and Cerakote Armor Black finish. This configuration balances range-capable ballistics with AR15 ergonomics for a versatile, modern sporting rifle.

Suggested optic: a low-power variable optic such as the Vortex Viper PST 1-6×24 provides a durable, high-quality sighting solution under $1,000 that complements the Resolute’s effective engagement range.

Applications: varmint and small-game hunting at longer ranges, and precision-oriented target work on the AR platform.
