CMMG Endeavor MK4 .22 ARC 20" 31-Round Threaded Barrel Bolt-Action Rifle

The CMMG Endeavor MK4 .22 ARC 20" 31-Round Threaded Barrel Bolt-Action Rifle represents a precision-engineered platform designed for shooters who demand accuracy and reliability in a modern intermediate cartridge package. Built on CMMG's proven Endeavor platform, this rifle bridges the gap between high-velocity centerfire performance and cost-effective training and hunting applications. The .22 ARC cartridge—a streamlined, efficient round—delivers consistent ballistics and reduced recoil, making this rifle ideal for precision rifle competitors, tactical trainers, and serious recreational shooters seeking a legitimate centerfire alternative to standard-velocity ammunition.

This bolt-action configuration ensures mechanical reliability and shot-to-shot consistency critical for long-range work and competition. The 20-inch threaded barrel accommodates suppressors and muzzle devices, giving operators the flexibility to tailor the rifle for noise reduction or specialized applications without permanent modifications. At 11.4 pounds, the rifle maintains a balanced handling profile suitable for both bench and field use, while the 31-round magazine capacity maximizes trigger time between reloads—a significant advantage during training cycles or competitive events. The bolt-action mechanics eliminate the complexity of semi-automatic systems, reducing maintenance requirements and delivering the inherent accuracy advantages shooters expect from precision rifle platforms.

Tactical instructors and law enforcement precision rifle teams benefit from the Endeavor MK4's straightforward manual-of-arms and inherent safety profile, while hunters and sport shooters gain a practical, accurate platform for medium-range applications. The threaded barrel design allows seamless integration of industry-standard suppressors and muzzle brakes, enhancing versatility for both suppressed and unsuppressed configurations. Ammunition compatibility with standard .22 ARC loads ensures reliable access to factory ammunition, and the rifle's modular design supports future upgrades and customization. This rifle delivers genuine precision-rifle capability without the operational or financial complexity of competing systems.
