CMMG Endeavor MK3 Features
The heart of the Endeavor MK3 is its 416 stainless steel barrel with a salt bath nitride finish (SBN), boasting a 1:10 twist rate for stabilizing a broad range of bullet weights. This precision barrel is paired with the CMMG ZEROED muzzle brake, significantly reducing recoil and muzzle rise to maintain accuracy shot after shot. The rifle’s direct impingement system is fine-tuned with a rifle-length gas system and a 0.936″ non-adjustable gas block, providing smooth and reliable operation.
Construction details include a billet 7075 T6 aluminum upper and lower receiver, ensuring the Endeavor MK3’s durability under rigorous use. The handguard is a CMMG EML15 M-LOK, offering versatility for accessory mounting. Finished in Cerakote, the rifle not only resists the elements but also presents a sleek, professional appearance.
