The Sig Sauer XRAY5 Advanced Red Dot Sight is a ruggedized, solid-state reflex optic featuring a fully enclosed, Argon-purged 7075 Aluminum housing with a Grade 5 Titanium top cover. Utilizing a patented Zero Distortion Optical System™, it projects an ultra-crisp 3.5 MOA Red Dot via a 225-pixel LED matrix that allows for precise Digital Zero™ adjustments with zero moving parts. The sight comes equipped with Bluetooth™ LightFight™ technology, which seamlessly pairs with compatible weapon lights to automatically boost reticle brightness the moment your illuminator activates. Optimized for heavy duty use on full-sized handguns using the SIG-LOC PRO footprint, it boasts an IPX8 waterproof rating up to 40 meters, extreme shock resistance tested to exceed 100,000 rounds of live-fire, and 15 brightness settings—including two dedicated for Gen 3+ night vision devices. Complete with MOTAC™ motion activation and a convenient side-mounted CR2032 battery compartment, it guarantees a reliable 10,000-hour runtime without sacrificing your backup iron sight co-witness.
