The CMMG Endeavor MK4 in .22 ARC is a precision-focused rifle purpose-built for extended-range capability beyond standard intermediate cartridge performance. Constructed on CMMG's proven Mk4 AR-15 platform, this 20-inch rifle combines the modularity and ergonomics of the AR ecosystem with the ballistic efficiency of the .22 ARC cartridge, delivering flat trajectories and reduced wind drift ideal for precision shooters and long-range training applications.
The 20-inch barrel length optimizes velocity and dwell time for the .22 ARC cartridge, a modern intermediate round engineered for superior ballistics and energy retention at distance. At 7.2 lbs, the rifle remains maneuverable while maintaining the structural rigidity demanded by precision shooting. The AR-15 platform architecture ensures compatibility with standard aftermarket components—triggers, grips, rails, and optic mounts—allowing shooters to customize the rifle to their specific requirements and duty profile without proprietary limitations.
This configuration serves competitive shooters, long-range precision practitioners, and law enforcement trainers seeking a low-recoil platform for skill development and extended-range work. The .22 ARC cartridge provides substantial velocity and energy compared to 5.56 NATO at equivalent ranges while generating significantly less recoil, reducing shooter fatigue during high-round-count training sessions. The CMMG Endeavor MK4 bridges intermediate and precision rifle applications, offering serious shooters a dedicated platform for accuracy-focused training without the cost and recoil demands of full-power rifle cartridges.
CMMG manufactures this rifle to AR-15 dimensional standards and material specifications, ensuring reliability and longevity in demanding conditions. The modular design and proven Mk4 platform foundation make the Endeavor MK4 .22 ARC a strategic investment for shooters building a multi-purpose precision battery while maintaining a single operating manual and maintenance protocol.
