The CMMG Resolute MK4 22 ARC — 16.1″ 10rd Armor Black is a carbine-length modern sporting rifle that puts the new 22 ARC cartridge into a proven AR15 platform. Built by CMMG with their ZEROED components and a RipStock, this rifle gives you flatter trajectory and better wind performance than a standard .223, without the weight of a full-size AR10. It’s a tool for the shooter who needs precision at range in a package that handles like a light carbine.

Key features
- 22 ARC chambering — WHY IT MATTERS: This cartridge pushes a .22-caliber bullet at velocities over 3,000 fps with less recoil than a .308, giving you 600-yard reach in a light carbine. Perfect for varmints, predators, or steel at distance.
- 16.1-inch threaded barrel — WHY IT MATTERS: The 1:7.5 twist stabilizes heavy 75-90 grain bullets, and the 1/2-28 threads let you mount a suppressor or brake without a gunsmith. Keeps the overall length short enough for truck or saddle scabbard.
- EML15 M-LOK handguard — WHY IT MATTERS: Full-length M-LOK slots let you attach a bipod, light, or grip exactly where you need it. The free-float design keeps barrel harmonics consistent for repeatable accuracy.
- RipStock — WHY IT MATTERS: This adjustable stock has a built-in cheek riser and a friction lock that won’t slip when you’re prone or shooting from cover. It’s stable and simple, no batteries or levers to fail.
- ZEROED trigger group — WHY IT MATTERS: A crisp, single-stage trigger at 4.5-5 lbs breaks clean with no creep. It’s not match-grade but it’s miles better than a mil-spec trigger, and it’s ready to run out of the box.
Who it’s for
This rifle is for the rancher who needs to reach coyotes at 400 yards without packing a heavy bolt gun. It’s for the rural shooter who wants a .22-caliber platform that can handle deer-sized pests inside 300 yards, but also punch paper at 600. If you’re tired of chasing .223 wind drift or recoil from a .308, the 22 ARC in this CMMG build gives you a middle ground that works.
Pros/Cons
- Pros: Lightweight (6.8 lbs), low recoil, 600-yard effective range, suppressor-ready barrel, reliable CMMG build quality.
- Cons: Ammo availability is limited compared to .223 or .308; you may need to order online or load your own. The 10-round magazine is restrictive for some uses, but aftermarket options are growing.

The CMMG Resolute fills a niche that neither the Geissele nor the Zev can touch: a light carbine with real reach. The Geissele is a battle rifle; the Zev is a handgun. For a rancher who needs to shoot far with minimal recoil, the 22 ARC is where it’s at.
FAQ
What is the effective range of the CMMG Resolute MK4 22 ARC?
With quality 75-90 grain ammunition, you can reliably hit targets out to 600 yards. The 22 ARC retains supersonic velocity past 800 yards, but practical accuracy for varmint hunting tops out around 500-600 yards depending on wind.
Does this rifle come with a muzzle device?
No. The barrel is threaded 1/2-28, but CMMG does not include a muzzle brake or flash hider. You’ll need to add your own, which is common for precision builds where shooters prefer specific suppressors or brakes.
Can I use standard AR15 magazines with the 22 ARC?
Yes and no. The 22 ARC uses the same magazine body as the 6.5 Grendel (modified AR15 magazines). Standard .223/5.56 magazines will not feed reliably. CMMG includes a 10-round magazine that works. Aftermarket 20- and 30-round options are available from CMMG and other manufacturers.
Is the CMMG Resolute MK4 legal for hunting?
Yes, in most states where .22-caliber centerfire rifles are allowed for varmint and predator hunting. Check your local regulations, as some states have magazine capacity limits or restrictions on semi-autos.
According to CMMG specs, the 22 ARC delivers 30% less wind drift at 500 yards compared to a .223 Remington with the same bullet weight. That’s a real advantage when you’re shooting across a pasture or canyon.
