CMMG 34A120F-AB RESOLUTE MK4 338ARC 16.1 ARMBLK

Made to combine the prowess of the AR15 platform with the stopping power of a large bore caliber, 338 ARC strives to emulate the sub or supersonic versatility of the now ubiquitous 300 BLK cartridge with more energy on target and less gas system tuning when switching from suppressed to unsuppressed. To maximize parts compatibility, 338 ARC utilizes the same bolt as 6.5 Grendel AR15s.
