CMMG 28B3D0CTI Endeavor 22 20" Bolt-Action Rifle

The CMMG 28B3D0CTI Endeavor 22 20" Bolt-Action Rifle is a purpose-built platform designed for shooters who demand precision, reliability, and lightweight handling. Built on CMMG's proven modular architecture, this rifle bridges the gap between tactical carbines and dedicated target platforms, making it ideal for law enforcement training, civilian marksmanship development, and precision shooting disciplines. The .22 caliber configuration delivers cost-effective practice and training without sacrificing accuracy or mechanical consistency, while the 20-inch barrel strikes a practical balance between velocity, maneuverability, and sight radius for both field and range applications.

The bolt-action design ensures reliable feeding and extraction across all ammunition types and velocities, a critical advantage when training with bulk or economical .22 rounds that may vary in pressure curves. With a total weight of just 5.5 pounds, the Endeavor 22 remains controllable during extended shooting sessions while the rigid bolt carrier and precision-fitted components maintain sub-minute-of-angle consistency shot after shot. The 20-inch barrel length optimizes velocity for long-range .22 performance while keeping overall length compact at 37.7 inches—essential for shooters transitioning between full-power rifles and rimfire platforms, or for those operating in vehicles and tight tactical environments.

This platform benefits law enforcement firearms instructors, military precision riflemen, competitive shooters, and civilian enthusiasts seeking a reliable, low-recoil training tool that builds fundamentals without the cost and concussion of center-fire ammunition. The CMMG Endeavor 22 integrates seamlessly into training regimens where shooters need high round-count repetition, trigger discipline development, and sight picture consistency. Its modular CMMG design ensures compatibility with standard .22 rimfire ammunition and aftermarket ergonomic upgrades, making it a scalable investment for both personal skill development and institutional training programs.
