Description

The 6mm ARC has earned a loyal following for one simple reason: it delivers long-range performance you'd normally need a bigger, heavier AR-10 to get, all from a standard AR-15 sized platform. The CMMG Resolute Mk4 takes full advantage of that. With a 16.1 inch barrel wearing a 1:7.5 twist, it stabilizes the heavy, high-BC 6mm bullets that make this cartridge shine, whether you're stretching steel past 600 yards or filling a deer tag. At just 6.44 pounds, it carries easily all day, and the Cerakote Coyote Tan finish looks as good in the truck as it does on the bench.

What Sets the Resolute Mk4 Apart

CMMG didn't cut corners on the small stuff. The Resolute comes loaded with their American-made ZEROED parts, including a drop-in single stage trigger, a 60/90 degree ambidextrous safety, ambi charging handle, ambi mag catch with extended release button, and a ZEROED muzzle brake to tame what little recoil the 6mm ARC produces. Lefties and right-handed folks alike get the same clean control layout, which is a nice touch you don't always see at this level.

Handguard and Stock Built for Real Use

The EML15 free-float M-LOK handguard runs slots at the 3, 6, 9, and 12 o'clock positions, trimming weight by skipping the full-length top rail while still giving you plenty of real estate for lights, bipods, and sling mounts. Out back, the six-position RipStock lets you snap it to your preferred length of pull fast, so the rifle fits you whether you're layered up in November or shooting in a t-shirt.

Feeding the Resolute Mk4

The rifle ships with one CMMG 10-round magazine and arrives without sights, leaving the top rail clean for the optic of your choice. A mid-power variable scope pairs beautifully with what this cartridge can do. Like every CMMG firearm, it's backed by the company's Lifetime Quality Guarantee, so you can put it to work with confidence.

Frequently Asked Questions

What is the 6mm ARC good for in a rifle like the Resolute Mk4?

The 6mm ARC was designed to bring extended-range ballistics to the AR-15 platform, rivaling cartridges that normally require a heavier AR-10. It shoots flat, recoils gently, and holds energy well past 600 yards, making it a strong pick for deer and predator hunting as well as long-range steel and target work. In a 6.44 pound carbine like this one, you get real reach without lugging around a big rifle.

Does the CMMG Resolute Mk4 come with sights or an optic?

No, it ships without sights, which is typical for a rifle in this class. The top rail is ready for whatever you want to mount, and most owners pair the 6mm ARC with a variable power scope to take advantage of the cartridge's range. A low-power variable or mid-power precision scope are both great fits depending on how you plan to use it.

Is the Resolute Mk4 friendly for left-handed use?

Yes, this is one of its strong suits. It comes standard with CMMG's ZEROED ambidextrous controls, including a 60/90 degree ambi safety, ambidextrous charging handle, and an ambi mag catch with extended release button. Southpaws can run the rifle just as smoothly as right-handed users without swapping any parts.

What magazines does the CMMG Resolute Mk4 in 6mm ARC use?

It uses 6mm ARC magazines, which share the same case head family as 6.5 Grendel, so Grendel-pattern AR-15 magazines are the standard here. One CMMG 10-round magazine is included in the box. Standard 5.56 magazines will not feed this cartridge reliably, so stick with mags built for 6mm ARC or 6.5 Grendel.
