Olight Osight X 3 MOA Red Dot & 32 MOA Circle - Compact Pistol Reflex Sight The Olight Osight X is an open reflex red dot sight tailored for pistols, featuring a versatile Multi-Reticle System with a precise 3 MOA dot for accuracy, a 32 MOA circle for rapid target acquisition, and their combination for balanced close-to-medium range engagements. Crafted from patented Olight Aluminum Alloy (OAL) with Type III hard anodizing—73% harder than standard 6061—it weighs just 46 g in a micro footprint (45x30x33 mm) with a 24x21.5 mm lens protected to IPX6 water resistance, operating reliably from 0°C to +45°C. Powered by an integrated 170 mAh Li-Po battery, it offers up to 57,000 hours runtime on dot mode, with 12 brightness levels (10 day/2 NV) controlled manually or via Auto Light Adjust, plus Motion Sensor auto-off after 10 minutes idle. Technical Specifications deliver key advantages: ±45 MOA windage/elevation adjustments at 1 MOA clicks enable quick zeroing on RMR-pattern slides (407c/507c compatible), while Multi-Coated lens minimizes glare for distortion-free views in dynamic scenarios. Hunters snap onto vital zones at speed, airsoft players dominate CQB with the expansive circle, and tactical shooters transition seamlessly without eye strain thanks to unlimited eye relief and both-eyes-open firing. Installation uses included screws and tool—align on slide cut, torque to spec; no batteries to swap, just magnetic USB-C docking station (IPX4, 800 mAh Li-Po) for overnight charges. Maintenance is effortless: wipe Multi-Coated glass with provided cloth.
