The CMMG Resolute Mk4 .338 ARC rifle in Tungsten Cerakote is a 16.1-inch AR15 that brings a large-bore cartridge to the carbine-length platform (brand part no. 34A120FTNG). The threaded barrel carries a ZEROED SVB brake on 5/8×24 threads, and a nitride-finished 4140CM barrel keeps the muzzle end tough. CMMG pairs it with an adjustable gas block, so tuning for suppressed or unsuppressed shooting takes less fuss. A RipStock, EML15 M-LOK handguard and ZEROED fire control and charging handle complete the build. It is a good fit for deer-sized game and for shooters who want a heavier, more energetic option from their AR.
