CMMG Endeavor & Resolute Rifles now Available in 6mm ARC

    CMMG 6ARC Endeavor

    The wave of 6mm ARC chambered platforms continues to grow after the launch of the new round. CMMG are the latest to announce that not one but two of their rifles will be available in the new 6ARC round.

    Heralded as their “newest long-range offerings” CMMG now offer both their Endeavor and Resolute rifles in 6ARC, with the rifles both shipping with a 10-round magazine. The Resolute has a medium tapered 16-inch barrel while the Endeavor features a 20-in, 1:7.5 twist, barrel.

    Here’s what CMMG have to say about their new 6mm ARC line:

    CMMG is proud to announce the addition of Hornady’s® 6mm ARC (Advanced Rifle Cartridge) to the RESOLUTE™ and ENDEAVOR™ families of rifles. Designed and engineered for accuracy and performance in the versatile AR15 platform, the 6mm ARC’s ballistic performance makes it ideal for precision shooting, hunting, military/law enforcement and recreational shooting.

    The Hornady 6mm ARC is a short-action cartridge designed to push the limits. Based on the 6.5 Grendel cartridge case, the 6mm ARC was designed to achieve comparable ballistics to the AR10 308 WIN, all while operating in a 30% lighter system.

    For shooters and hunters who need to reach further distances, the 6mm ARC will be available in 108gr ELD Match® (match ammo), delivering a muzzle velocity of 2750 fps and the 103gr ELD-X® (precision hunter ammo) with 2800 fps. Less felt recoil provides both shooters and hunters the ability to stay on target after making the shot and the potential for quicker follow-up shots with the AR15.

    CMMG RESOLUTE™ and ENDEAVOR™ 100, 200 and 300 Series come with a rifle-length gas system on both the 16” RESOLUTE barrel and 20” ENDEAVOR barrel. This allows for the rifles to have less felt recoil and lower extraction force, reducing wear and tear.

    RESOLUTE™ rifles will have a MSRP ranging from $1,049.95 to $1,649.95 (series pending) and the ENDEAVOR™ rifles with a MSRP ranging from $1,049.95 to $1,799.95 (series pending). CMMG 6mm ARC rifles will be available from CMMG’s website, stocking dealers, qualified retailer stores and their websites.

    Both the RESOLUTE™ and ENDEAVOR™ rifles ship with one 10-round detachable box magazine.
