Barrel length is a big consideration when it comes to long-range rifles luckily the 20-inch ENDEAVOR Mk3 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 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. - Platform: Mk3 - Caliber: 6.5 Creedmoor - Operating System: Direct Impingement - Barrel Length: 20 - Barrel Twist: 1:8 - Barrel Contour: MT - Barrel Material: 416SS SBN - Muzzle Device: CMMG ZEROED Muzzle Brake - Muzzle Thread: 5/8 X 24 - Gas Port Location: Rifle - Gas Block: 0.750 Non-Adjustable - Upper Receiver: Billet 7075 T6 Aluminum - Lower Receiver: Mk3 Billet 7075 T6 - Hand Guard: CMMG EML15 M-LOK - Finish: Cerakote Standard - Charging Handle: CMMG ZEROED Ambi - Pistol Grip: CMMG ZEROED Pistol Grip - Buffer Type: Rifle Mk3/AI - Receiver Extension: CMMG A1 Extension - Stock / Brace: Magpul MOE Rifle Stock - Trigger Type: Mil-Spec Single Stage - Trigger Guard: Integrated - Safety Selector: CMMG ZEROED 60/90 Degree - Magazine: Magpul 20rd PMAG - Weight: 8.9 - Length: 41.3
