If you want to deliver a hard hitting round at long-range and still have a well-balanced rifle when walking through the field, the 20-inch ENDEAVOR® Mk3 in .308 WIN is a prime candidate for the job. Trusted for decades by hunters and marksmen alike, .308 WIN delivers excellent results up close and at extended distances and can pack quite a punch.
Carrying on the AR15's reputation for modularity, CMMG® builds our larger caliber rifles like .308 WIN & 6.5 Creedmoor on our Mk3 (AR-10) size platform, which is based on the LR-308/DPMS Gen 1 high-pattern design.
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.
