<p>Experience firsthand red-dot technologies trusted by armed forces around the world with the SIG SAUER® ROMEO-X Pro Enclosed Sight, crafted after the MIL-SPEC ROMEO-M17. Its compact footprint is especially suited for semi-auto pistols. Fully enclosed, high-efficiency point-source emitter with an easy-to-see dot reticle promotes fast, effortless target acquisition. Plus, 15 illumination settings, including 3 night-vision modes, helps you stay on point under a full range of lighting conditions. Low deck height allows you to co-witness with standard-height iron sights. ALT™ lens system features ultra-wide broadband, anti-reflection SpectraCoat™ lens coatings to reduce surface reflections across the entire visible spectrum for superior light transmission. D.A.R.C. lens coatings and reticle brightness settings optimize compatibility with GEN 3+ night-vision devices. Motac™ motion-sensing technology powers up illumination when it senses motion and powers down when not in use to extend battery life. Additionally, MAGNETAC™ technology automatically turns the Romeo-X Pro off when it's placed into a MAGNETAC-compatible holster (not included) and powers it back on when you draw the Romeo out again. CNC-machined 7075 aluminum housing, distortion-free aspherical glass lenses, and beryllium copper flexure system deliver long-lasting, reliable performance. Powered by one CR-1632 battery (included) for up to 20,000 hours.</p> <ul> <li>Compact footprint is ideal for semi-auto pistols</li> <li>Fully enclosed, high-efficiency point-source emitter with an easy-to-see dot reticle</li> <li>15 illumination settings, including 3 night-vision modes</li> <li>Low deck height lets you co-witness wit hstandard-height iron sights</li> <li>ALT lens system with ultra-wide broadband, anti-reflection SpectraCoat lens coatings</li> <li>D.A.R.C. lens coatings and reticle brightness settings for use with GEN 3+ night-vision devices</li> <li>Motac technology powers up illumination when it senses movement</li> <li>MAGNETAC automatically turns the Romeo-X Pro off when it's placed into a MAGNETAC-compatible holster</li> <li>CNC-machined 7075 aluminum housing</li> <li>Distortion-free aspherical glass lenses</li> <li>Beryllium copper flexure system</li> <li>Includes CR-1632 battery with runtime of up to 20,000 hours</li> </ul>
