The Sig Sauer XRAY5 Compact and FOXTROT2R LightFight Combo Kit pairs an ultra-rugged, enclosed 3.5 MOA reflex sight with an advanced 700-lumen weapon light for a seamless, interconnected tactical ecosystem. Utilizing an integrated Bluetooth™ LightFight™ connection, the system automatically scales up your reticle's brightness the exact moment the weapon light is activated by its ambidextrous paddles. The enclosed optic features a 7075 Aluminum housing wrapped in a Grade 5 Titanium top shield, resulting in a solid-state system with zero moving parts that is live-fire tested to exceed 100,000 rounds. Engineered for everyday carry, subcompact defense, and night-vision operations, the optic offers 15 brightness settings (including 2 NV modes), while the light pumps out an intense 20,000 peak candela of target-identifying white light. Ready to deploy out of the box on compact Shield RMSc footprint firearms, this package includes a side-access CR2032 battery for the sight and two high-capacity 16340 rechargeable Li-ion batteries for the illuminator.
