ENDEAVOR, Mk3, 6.5 Creedmoor, 24"
Ready to push the long-range limits to what you thought was possible with an AR? This ENDEAVOR® Mk3 chambered in 6.5 Creedmoor may be just the rifle you need. Even though 6.5 Creedmoor has a much shorter history than the commonly compared .308 WIN, it was designed specifically for hitting long-range targets while generating less recoil.
This ENDEAVOR utilizes a 24-inch 416 stainless steel barrel with a nitride finish to better realize the potential of the 6.5 Creedmoor cartridge, along with the AR10-sized Mk3 (LR-308/DPMS Gen 1 high-pattern) receivers.
Check out our CMMG® Resources article to learn more about the Mk3 platform.
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.
ZEROED parts and accessories – Quality comes standard
The AR platform is well known for its capability for customization but picking the right parts doesn’t have to be a nightmare of homework. CMMG’s ZEROED parts and accessories are made here in the USA with quality and attention to detail that is second to none and each ENDEAVOR comes equipped with a slew of ZEROED parts standard, including:
ZEROED .308 Ambi Charging Handle
ZEROED Extended Mag Release Button
