Sig Sauer ROMEO3XL 1x35mm 3MOA Open-Reflex Sight

Featuring a durable, shockproof, CNC-machined aircraft aluminum housing, the Sig Sauer® ROMEO3XL 1x35mm 3MOA Open-Reflex Sight is the ideal companion for sporting rifles, carbines, SMGs, optics-ready pistols, and tactical shotguns. A high transmittance red notch reflector delivers unmatched brightness, eliminates distortion, and maximizes light transmission for optimal clarity. MOTAC™ (Motion Activated Illumination System) technology automatically activates the 3 MOA illuminated red dot reticle when it senses motion, and powers down the unit when the weapon is idle for reliable battery preservation. 12 user-selectable brightness settings (10 daylight; 2 night vision) ensure reliable visibility in all lighting conditions, while the included low-profile 1913 Picatinny mount readily attaches to most firearm platforms for maximum versatility. The side-loading battery compartment makes it easy to replace the CR2032 battery (included) without removing the sight or affecting zero and features up to 25,000 hours of battery life on the lowest setting. IPX7 waterproof and fogproof.
