Product Description
The CMMG Resolute Mk4 in 338 ARC is built to blend AR-15 platform handling with large bore performance, delivering strong energy on target in both suppressed and unsuppressed setups with reduced gas system tuning compared to similar cartridges. This upper assembly features a 16.1 inch black nitride barrel with a 1:8 twist optimized for traditional .338 caliber projectiles, plus a Black Armor Cerakote finished aluminum receiver for durability and corrosion resistance. To maximize parts compatibility, the 338 ARC design uses the same bolt as 6.5 Grendel AR-15 systems.
