Sig Sauer ROMEO4S 1x20mm Ballistic Circle Red Dot Sight

The Sig Sauer® ROMEO4S 1x20mm Ballistic Circle Red Dot Sight features a durable, shockproof, CNC-machined aircraft aluminum housing, designed to deliver long-lasting strength and corrosion resistance. SpectraCoat™ lens coatings deliver enhanced color fidelity and light transmission for optimal clarity, while integrated see-through lens covers protect against scratches, bumps, and abrasions during storage and transport. The illuminated ballistic circle dot reticle offers quick, intuitive target acquisition, 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 reliable 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 rail-equipped rifle, carbine, and shotgun 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. IPX7 waterproof and fogproof.
