The CMMG Endeavor MK4 .22 ARC 20 Stainless AR Rifle represents a precision platform purpose-built for shooters seeking efficient, low-recoil performance without sacrificing practical accuracy. Chambered in .22 ARC, this modern intermediate cartridge delivers ballistics superior to traditional .22 Long Rifle while maintaining manageable recoil and cost-effective practice or small-game hunting applications. This rifle fills a critical niche for law enforcement trainers, competitive marksmen, and recreational shooters who demand a duty-grade AR platform without the thermal signature or expense of centerfire ammunition.
Built on the proven AR-15 ergonomic and mechanical foundation, the Endeavor MK4 features a 20-inch stainless barrel that provides extended sight radius and consistent velocity for accurate shot placement beyond 100 yards. The stainless construction resists corrosion in humid or marine environments—critical for duty weapons or long-term storage in variable conditions. At 11.4 pounds fully assembled, the rifle balances controllability with stability, allowing shooters to engage targets with minimal vertical dispersion. The modular AR design permits optic mounting, furniture customization, and accessory integration, enabling configuration for specific mission requirements or individual preferences without proprietary tools or gunsmithing.
This platform excels for military and law enforcement transition training, defensive skill sustainment, or high-round-count qualifications where ammunition expense becomes a controlling factor in training frequency. Civilian competitive shooters leverage the .22 ARC's inherent accuracy and flat trajectory for precision rifle matches or varmint work. Standard AR-15 magazines, rail systems, and optic mounts ensure seamless integration with existing inventory, eliminating the need for specialized support infrastructure. Before purchase, verify your jurisdiction's regulations regarding rifle ownership and transporting firearms across state lines.
