CMMG Endeavor MK4 Tungsten .22 ARC 20″ Barrel 30-Rounds

CMMG Endeavor Features

This rifle is designed with a 20″ stainless steel barrel that is finished in black nitride, offering superior corrosion resistance and longevity. The barrel is threaded (1/2″x28 thread pattern) and comes equipped with a CMMG Zeroed muzzle brake, significantly reducing recoil and muzzle rise for improved accuracy and faster follow-up shots. The Endeavor’s overall length of 37.80″ strikes an ideal balance between accuracy-enhancing barrel length and maneuverability.

Ergonomics are a key focus of the Endeavor’s design, featuring a Magpul synthetic stock and CMMG Zeroed grips for comfortable handling and control. The EML 15″ M-LOK handguards provide ample space for mounting accessories while keeping the rifle’s profile slim and manageable. The rifle’s aluminum receiver, finished in Tungsten Gray Cerakote, not only adds to its visual appeal but also offers added protection against the elements and wear.
