The CMMG Resolute Mk4 6mm ARC rifle delivers genuine extended-range performance in a compact carbine that won't beat you down on the trail or tire you out at the range. Built around the 6mm ARC cartridge—a 2020-era round engineered to punch well above its weight class in AR15-length platforms—this 16.1" barrel gun bridges the gap between short, handy setups and the heavier, longer AR10s that dominate long-range precision work. If you hunt or shoot at distance but refuse to lug a full-size rifle, the Resolute Mk4 in coyote tan answers that call.
CMMG equipped this rifle with purpose-built parts throughout. The direct impingement system runs proven, simple, and easy to maintain. You get a 416 stainless steel barrel (1:7.5 twist, rifle-length gas port) topped with CMMG's ZEROED muzzle brake, both engineered to handle 6mm ARC's ballistics consistently. The billet upper and forged lower receivers are premium aluminum, finished in durable Cerakote. The EML 15 M-LOK handguard strips weight while keeping mounting slots where they matter—12, 3, 6, and 9 o'clock—so you can hang optics, lights, or bipods without unnecessary bulk. Inside, you'll find CMMG's ZEROED drop-in trigger, ambidextrous charging handle, and 60/90-degree safety selector. The RipStock carbine buffer system and 6-position receiver extension let you dial in length of pull, and the included 10-round magazine gets you started.
At 6.4 lbs and 32.5" overall, the Resolute Mk4 6mm ARC won't disappear into a truck or pack, but it won't slow you down either. Whether you're glassing a ridgeline, working steel plates at 500 yards, or simply want a rifle that handles like a carbine but performs like a distance gun, this CMMG delivers the ballistics and build quality to back it up.

Frequently Asked Questions
What is 6mm ARC and why would I choose it over .223 Remington?
The 6mm ARC (Advanced Rifle Cartridge) was introduced in 2020 specifically to deliver extended-range ballistic performance that rivals larger AR10-platform rifles, all within the AR15 form factor. While .223 is proven and versatile, 6mm ARC excels at distance, making it the choice for hunters and target shooters who want flat trajectory and consistent accuracy beyond typical carbine range without carrying a full-size rifle.
Is this rifle suitable for hunting?
Yes. The 6mm ARC was designed with hunting in mind, and CMMG built the Resolute Mk4 as a hunter-friendly platform. The compact 16.1" barrel and lightweight build (6.4 lbs) make it easy to carry in rough terrain, while the cartridge's ballistic performance is suited to medium-game hunting at extended ranges where most AR15 rounds fall short.
What comes in the box?
The rifle ships with one 10-round magazine. Additional accessories such as optics, slings, or ammunition are not included.
Can I mount optics and accessories on the EML 15 handguard?
Yes. The CMMG EML15 M-LOK handguard features mounting slots at the 12, 3, 6, and 9 o'clock positions, so you can attach optics, lights, bipods, or other accessories where they're most useful. The 5/8 x 24 muzzle brake thread will also accept standard suppressors or other muzzle devices if you choose to swap the brake.
Is the safety selector and charging handle truly ambidextrous?
Yes. Both the CMMG ZEROED safety selector (with 60/90-degree throw) and the ZEROED ambidextrous charging handle are designed for use by shooters of either hand dominance.
