Sig Sauer ROMEO4H 1x20mm Horseshoe Green Dot Sight

The Sig Sauer® ROMEO4H 1x20mm Horseshoe Green Dot Sight is an ultrareliable, compact optic, designed to deliver quick, intuitive target acquisition in virtually any lighting. This Sig optic features a durable, shockproof, CNC-machined aircraft aluminum housing with precision-molded aspheric lens technology, eliminating aberration, reducing weight, and focusing images through the lenses for superior optical performance. SpectraCoat™ coatings offer enhanced color fidelity and light transmission for optimal clarity. Powered by an efficient green LED emitter for daylight visibility, the green horseshoe reticle is activated by MOTAC™ (Motion Activated Illumination System) technology, which automatically activates the illuminated reticle when it senses motion, and powers down the unit when the weapon is idle for battery preservation. 12 user-selectable brightness settings (10 daylight; 2 night vision) ensure reliable visibility in all lighting conditions, while the included true co-witness QR mount and 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 50,000 hours of battery life on the lowest setting. IPX7 waterproof.
