CMMG 28B3D0CMB Endeavor 22 20" Bolt-Action Rifle

The CMMG 28B3D0CMB Endeavor 22 20" Bolt-Action Rifle is purpose-built for shooters who demand precision and reliability in a lightweight, highly portable platform. Chambered in .22 Long Rifle, this rifle delivers the accuracy benefits of a bolt-action design without the recoil and noise signature of centerfire calibers—making it ideal for training, small game hunting, and extended practice sessions where cost-per-round and shooter fatigue are operational considerations. Law enforcement firearms instructors and military small arms coaches frequently select .22 bolt-action rifles for marksmanship fundamentals training, as they allow shooters to focus on sight picture, trigger control, and breathing without managing significant recoil impulse.

The Endeavor 22 features a 20-inch barrel optimized for .22 LR ballistics, delivering consistent velocity and accuracy at typical training and hunting distances. Its bolt-action mechanism—a time-proven operating principle—ensures reliability, straightforward maintenance, and inherent safety characteristics that make it suitable for supervised shooting environments. At 5.5 pounds unloaded, the rifle remains compact and maneuverable in field conditions while maintaining sufficient mass for consistent shot control and minimal vibration during precision shooting. The 38-inch overall length keeps the platform nimble for transportation and storage without sacrificing sight radius or ergonomic reach.

This rifle benefits shooters ranging from competitive smallbore competitors and junior marksmanship programs to experienced hunters and armed professionals building foundational skills. The lightweight, handy package excels in environments where noise and blast are concerns—indoor ranges, suburban properties, and training facilities with noise restrictions favor the .22 platform. Standard .22 LR ammunition availability, affordability, and ballistic consistency make extended practice sessions economical and sustainable, supporting high-round-count training protocols typical in professional shooting development programs.
