The CMMG Endeavor MK4 in .22 ARC is a modern intermediate-caliber rifle purpose-built for extended-range precision and reduced recoil compared to larger centerfire cartridges. This rifle delivers repeatable accuracy at distance while maintaining the AR15 platform's modularity, allowing operators and precision shooters to leverage a vast ecosystem of compatible components and accessories for customization and field adaptation.
The Endeavor MK4 features a 416 stainless steel barrel with Nitride finishing, which hardens the surface for enhanced corrosion resistance and extended service life in variable weather conditions. The rifle ships with a Magpul MOE stock, offering an ergonomic and proven platform for adjustable length of pull. A ZEROED muzzle brake comes installed, managing recoil and allowing for faster target reacquisition during rapid fire sequences. The 15-inch EML handguard maximizes rail real estate with M-LOK slots positioned at 12, 3, 6, and 9 o'clock, providing unrestricted options for mounting optics, lights, grips, and other tactical accessories. At 11.6 lbs, the rifle balances firepower with shootability for extended engagements or field operations.
The .22 ARC cartridge fills a niche between 5.56 NATO and larger magnum calibers, offering flatter trajectories and reduced wind drift at distance while maintaining manageable recoil and ammunition availability. This makes the Endeavor MK4 suitable for precision rifle enthusiasts, long-range training, and hunters seeking a lightweight platform with superior ballistic efficiency. The rifle's AR15 compatibility ensures that shooters can source triggers, grips, charging handles, and optic mounts from an extensive aftermarket, keeping total system cost reasonable while maintaining performance standards.
