For decades, optics and weapon lights have operated independently. The XRAY5 and FOXTROT2R LightFight Combo Kit changes that. Pairing the world's first Solid-State Advanced Red Dot Sight with the industry's first LightFight-enabled weapon light, the XRAY5 and FOXTROT2R wirelessly communicate to deliver faster, more intuitive target engagement in dynamic lighting conditions. Rather than relying on ambient light surrounding the shooter, LightFight automatically adjusts the XRAY5 reticle brightness based on the activation or deactivation of the FOXTROT2R's light to ensure optimal reticle visibility exactly where it matters. Built around XRAY5's revolutionary solid-state architecture, patented Zero Distortion Optic (ZDO) system, Digital Zero technology, and advanced capabilities including multiple stored zero profiles and Round Counter, the package delivers an entirely new level of durability, precision, and intelligence. Combined with the FOXTROT2R's 700-lumen output, 20,000 candela beam intensity, programmable controls, and FlexCore dual-fuel system, the result is a seamlessly integrated platform engineered to perform as one. The future of pistol optics isn't just smarter. It's connected. Precision Built. Precision Kept.
