CMMG 28B3D0CTNG Endeavor 22 20" Rifle

The CMMG Endeavor 22 ARC 20" rifle is a precision-engineered platform engineered for shooters demanding sub-MOA accuracy without the recoil penalty of traditional centerfire rounds. Chambered in 22 ARC—a modern intermediate cartridge that bridges the ballistic gap between .22 Hornet and .223 Remington—this rifle delivers flat trajectories and minimal drift while maintaining shooter control and follow-up capability. The 20-inch barrel optimizes velocity and sight radius for tactical applications, hunting, and distance shooting competitions where precision and consistency are non-negotiable.

At 5.5 lbs, the CMMG Endeavor delivers a lightweight platform that reduces fatigue during extended range sessions or field operations. The compact dimensions—37.9 inches overall length, 6.4-inch height, 3.4-inch depth—enable easy transport, storage, and maneuverability in tight spaces without sacrificing ergonomics or sight plane height. The 22 ARC cartridge generates approximately 50% less recoil than 5.56 NATO, accelerating target acquisition and enabling rapid follow-up shots with superior accuracy potential. This combination makes the Endeavor particularly suited for precision rifle courses, defensive carbine training, and precision hunting applications where shot placement is paramount.

The CMMG Endeavor 22 ARC appeals to dedicated marksmen, LEO training units, and competitive shooters seeking a dedicated precision platform with significantly reduced ammunition costs compared to full-power rifle rounds. 22 ARC ammunition delivers superior ballistic coefficients and velocity retention beyond 500 yards while remaining accessible in price. This caliber has gained adoption among precision rifle competitors and serious hunters targeting varmint and small-to-medium game where wind drift and bullet drop must be managed without excessive recoil disturbance. The rifle's lightweight profile and moderate recoil make it ideal for shooters managing cumulative range time or those seeking to develop precision fundamentals without the wear associated with larger cartridges.
