Traditional pistol optics have spent decades refining the same mechanical architecture. The XRAY5 was built to replace it. The XRAY5 Advanced Red Dot Sight redefines what shooters should expect from a pistol optic. Built on an innovative solid-state architecture featuring a rigid 225-dot matrix with no moving parts to wear or drift, the XRAY5 delivers unmatched durability and repeatable precision under the harshest conditions. The patented Zero Distortion Optic (ZDO) system delivers the industry's clearest pistol optic sight picture to date, while intuitive Digital Zero technology allows shooters to establish, save, and instantly recall multiple zero profiles through the XRAY5 App. Combined with LightFight adaptive illumination, intelligent Round Counter functionality, and a fully enclosed optical system, the XRAY5 introduces an entirely new level of capability without compromising reliability. Designed, developed, tested, and assembled in the USA, the XRAY5 is more than an evolution of the pistol optic; it is a new foundation for what a red dot sight can be. Precision Built. Precision Kept.
