CMMG Endeavor MK3 Features
The rifle boasts a 416 stainless steel barrel with a salt bath nitride finish (SBN) and a 1:8 twist rate, optimized for stabilizing a wide range of bullet weights, ensuring precision with every shot. The CMMG ZEROED muzzle brake effectively reduces recoil and muzzle rise, enhancing shooter comfort and follow-up shot accuracy. This model operates on a direct impingement system and features a rifle-length gas system with a 0.750 non-adjustable gas block for reliable cycling.
Constructed from billet 7075 T6 aluminum, both the upper and lower receivers offer durability without compromising weight. The rifle is adorned with a Cerakote finish for added resilience against wear and corrosion. The CMMG EML15 M-LOK handguard provides ample space for accessory attachment, making the rifle highly customizable to fit the shooter’s needs.
