Sig Sauer Romeo-X Pro Open Reflex Red Dot Sight

Sig Sauer Romeo-X Pro Open Reflex Sight
The Romeo-X represents the culmination of Sig Sauer's extensive experience in military-grade red dot technology, refined into a streamlined package for the civilian shooter. This is a sight built to perform.
Core Design
The Romeo-X features a CNC-machined 7075 aluminum housing that delivers the durability you expect from a professional-grade optic. The open emitter design provides an unobstructed sight picture, while the distortion-free aspherical lens ensures clarity across the entire field of view. At just 0.94 inches in height, the low deck profile allows you to co-witness with standard-height iron sights—a practical advantage for shooters who value backup aiming systems.
Reticle and Aiming
The sight projects a 2 MOA red dot surrounded by a 32 MOA circle, with both elements individually selectable. This dual-reticle system gives you flexibility in how you aim, whether you prefer the precision of the dot or the reference of the circle for rapid target acquisition.
Brightness and Battery
With 15 illumination settings—12 for daylight and 3 for night vision compatibility—the Romeo-X adapts to virtually any lighting condition. The MOTAC (Motion Activated Illumination) technology conserves battery power by activating the reticle only when motion is detected. A single CR1632 battery mounted on the side delivers an impressive 20,000 hours of runtime, meaning you can leave it on and forget about it for months.
Mounting and Adjustment
The sight mounts directly to optics-ready pistols using standard R1P/R2 and DeltaPoint Pro footprints, as well as Shield RMSc mounting systems. Elevation and windage adjustments are made with intuitive buttons, with 1.5 MOA per click for precise zeroing. Total travel is 80 MOA in both directions—more than enough for any practical shooting scenario.
Durability
Designed, tested, and assembled in the USA, the Romeo-X is IPX-7 waterproof, meaning it will function reliably even when submerged in shallow water. At just 1.15 ounces, it adds minimal weight to your carry gun.
This is a sight for shooters who demand reliability without compromise.
