CMMG Resolute Mk4 338 ARC

The CMMG Resolute Mk4 338 ARC (Advanced Rifle Cartridge) is tailored for long range performance and terminal ballistics. This precision configured AR style rifle is built on CMMGs Mk4 platform and combines the prowess of the AR15 platform with the stopping power of a large bore caliber. Utilizing a direct impingement system, the Resolute Mk4 338 ARC features a 16.1 inch chrome moly steel barrel, finished in black nitride for enhanced corrosion resistance with an 1:8 twist. Engineered for accuracy, durability and adaptability, every CMMG Resolute MK4 338 ARC is complete with an optimized gas system and is engineered to emulate the sub or supersonic versatility of the 300 BLK cartridge with more energy on target with less gas system tuning when switching from suppressed to unsuppressed.

Every CMMG Resolute Mk4 338 ARC is equipped with a CMMG Zeroed single-stage trigger that gives a clean, repeatable break, along with faster follow-up shots. Fitted with a Zeroed muzzle brake, threaded at 5/8x24, reduced recoil and muzzle rise is prominent. Additionally the full-length Picatinny top rail and lightweight M-LOK handguard offer expansive real estate to mount accessories. Comfort and control, on the Resolute Mk4 338 ARC, are elevated with CMMG's Zeroed pistol grip and adjustable polymer stock. Shipped with a 10 round magazine, this rifle is just 6.2 pounds with an overall length of 37.3 inches, delivering a perfect balance between mobility and stability. CMMG utilizes the same bolt as the 6.5 Grendel AR15s to maximize parts compatibility. For shooters that like to load their own ammo, CMMG 338 ARC barrels feature a slower twist to allow the use of traditionally constructed .338 caliber projectiles.
