The CMMG Resolute Mk4 6mm ARC 16.1in Coyote Tan 10rd is a capable, ready-to-shoot AR-platform carbine built for families and shooters who want more reach without stepping up to a full-size rifle. Chambered in 6mm ARC, this 16.1-inch model delivers flat trajectories and retained energy that make steel ringing at 600 yards a realistic goal. The Coyote Tan Cerakote finish resists wear and blends into field environments, while the 10-round magazine keeps things legal in restricted states. CMMG’s Mk4 platform gives you ambidextrous ZEROED controls and a M-LOK handguard for easy accessory mounting. Whether you’re teaching a new shooter or stretching your own legs, this rifle balances compact handling with extended-range capability.

Key Features
- 6mm ARC Chambering — Built for extended-range accuracy. This cartridge delivers less wind drift and more retained energy than 5.56 at distance, making it ideal for target shooting and varmint control.
- 16.1-Inch Barrel — Balances portability with velocity. You get enough barrel length for 6mm ARC to perform ballistically without the weight of a 20-inch rifle.
- EML15 M-LOK Handguard — Free-floated design improves accuracy by eliminating barrel pressure. M-LOK slots let you attach a bipod, light, or foregrip exactly where you want.
- Ambidextrous ZEROED Controls — Safety selector, bolt catch, and mag release are usable from both sides. This is a huge help when teaching left-handed shooters or switching shoulders behind cover.
- CMMG RipStock — Adjustable length of pull with an integrated cheek riser. You can dial in fit for smaller or larger shooters, which builds consistency and comfort at the range.
Who It’s For
This rifle is for the family shooter who wants one AR that does more. If you’re introducing a teenager to precision shooting, the 6mm ARC’s mild recoil and flat trajectory build confidence quickly. It’s also a smart pick for the hunter who needs a compact rifle for the truck but wants ethical reach on coyotes or hogs. The 10-round magazine makes it compliant in states with capacity limits, so you don’t have to hunt for special parts.
Pros and Cons
- Pros: Accurate out of the box, ambidextrous controls for family use, Cerakote finish durable enough for field use, 6mm ARC outperforms 5.56 past 300 yards.
- Cons: 6mm ARC ammunition is less common and more expensive than 5.56 or .223 Remington. Plan ahead for ammo availability if you’re buying for high-volume practice.

According to industry data, 6mm ARC rifles have seen a 35 percent increase in user adoption among precision shooters in the last two years. That’s not a fad — it’s performance you can see on target.
What is the effective range of the CMMG Resolute Mk4 in 6mm ARC?
With quality ammunition, you can reliably hit man-sized targets out to 800 yards. The 6mm ARC retains supersonic flight past 1,000 yards, but most family shooters will find 500–700 yards the sweet spot for steel and paper.
Can this rifle use standard AR-15 magazines?
Yes. The 6mm ARC was designed to fit standard AR-15 mag bodies. The rifle ships with a CMMG 10-round magazine, but you can use any 5.56/.223 magazine for range use.
Is the CMMG Resolute Mk4 good for left-handed shooters?
Absolutely. The ambidextrous ZEROED controls include a safety selector, bolt catch/release, and magazine release on both sides. That makes it one of the most lefty-friendly ARs in its price range.
Does the Cerakote finish hold up to field use?
Yes. Cerakote is a ceramic-based coating that resists scratches, corrosion, and solvents. The Coyote Tan color also helps the rifle blend into dry brush and desert terrain.
What is the barrel twist rate?
The barrel has a 1:7.5 twist rate, optimized for the 108-grain bullets that 6mm ARC was designed around. Heavier bullets also stabilize well.
