Design and construction
The ENDEAVOR MK4 reflects Cmmg’s attention to durable materials and tactical ergonomics. The 18″ barrel is optimized for consistent muzzle velocity with 5.56mm loads while keeping overall length manageable.

Built as a Semi Auto platform, it accepts common AR-pattern accessories and optics.
