CMMG ENDEAVOR, Mk3,.308WIN, 24″

ENDEAVOR, Mk3,.308WIN, 24″

Coming in at 24 inches, this ENDEAVOR® Mk3 has the longest barrel CMMG® offers in .308 WIN. Pair it with your preferred optic of choice and you’ve got a fantastic long-range rifle. Material selection is key to a quality rifle, which is why the barrel on this .308 ENDEAVOR is made from 416 stainless steel with a nitride finish for durability and corrosion resistance without sacrificing performance.

Built on our Mk3 (AR-10 size) platform to safely handle larger calibers like .308 WIN, the Mk3 is based on the LR-308/DPMS Gen 1 high-pattern design. Check out our CMMG Resources article to learn more.

Each CMMG ENDEAVOR rifle is purpose-built for long-range performance, with everything from the Magpul® MOE® rifle stock to the ZEROED™ muzzle brake, and every part in between selected for its utility to the avid marksman.

The EML™ 15 handguard maximizes customization potential. M-LOK® attachment slots at the 12, 3, 6, and 9 o’clock positions give you plenty of real estate to mount accessories, while the Picatinny rail sections allow for easy and solid mounting points for sights and accessories.
