Barrel length is a big consideration when it comes to long-range rifles, luckily the 20-inch ENDEAVORMk3 in 6.5 Creedmoor hits the sweet spot of maneuverability and performance. Designed for long-range shooting, 6.5 Creedmoor has quickly become a favorite of many because of its flatter trajectory and lower recoil than .308 WIN.They say bigger is better, which is exactly why this ENDEAVOR is built on the bigger and beefier Mk3 (LR-308/DPMS Gen 1 high-pattern) receiver platform to handle larger calibers like 6.5 Creedmoor.Each CMMGENDEAVOR rifle is purpose-built for long-range performance, with everything from the MagpulMOErifle stock to the ZEROED(TM) muzzle brake, and every part in between selected for its utility to the avid marksman.The EML(TM) 15 handguard maximizes customization potential.
