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 duty, 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.
