Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro 1x24mm 6 MOA Green Dot Reflex Sight - Black

The Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro is a fully enclosed, military-grade reflex sight purpose-built for Sig-Loc-equipped pistols. Built around a sealed 7075 aluminum housing, this optic is engineered to withstand recoil and the elements while delivering a clean, repeatable aiming point. It is finished in matte black for a low-glare profile.

At the heart of the sight is a crisp 6 MOA green dot reticle projected through a 1x24mm window. The dot is illuminated in green and adjustable across 15 brightness settings, allowing the shooter to tune the reticle to ambient light. The side-loading CR2032 battery delivers extended runtime so the optic stays ready without removal from the slide.

The defining feature of this variant is the proprietary Sig-Loc mounting footprint, which establishes five points of contact between the optic and the slide for a secure, repeatable lock-up. This direct-mount design is intended for full-size Sig-Loc-compatible pistols, and the low deck height supports standard-height iron sight co-witness.

At just 1.90 inches long and weighing only 1.15 oz, the Romeo-X Sig-Loc Pro adds minimal bulk to the host pistol. As a current-production optic from Sig Sauer Electro-Optics, it ships new from the factory and is ready for immediate installation.
