SIG SAUER Romeo-X SIG-Loc Enclosed Pistol-Mounted Red Dot Sight (Black) (Used)
Condition: Used – Like New
Condition Details: Fully functional with no visible wear; original packaging included (may show light handling).
The SIG SAUER ROMEO-X SIG-LOC Pistol-Mounted Circle Red Dot represents the next evolution in handgun optics, built around the SIG-LOC (Leverage Optimized Connection) system originally developed for the MIL-SPEC ROMEO-M17. Designed for exceptional strength, precision, and reliability, the ROMEO-X delivers professional-grade performance for both civilian and duty use.
SIG-LOC Mounting System
SIG-LOC introduces an innovative low-profile mounting footprint that creates five total points of contact between the optic and slide. This design eliminates zero shift caused by recoil and impact, providing one of the strongest and most stable optic-to-slide connections available.
Reduced Parallax & Clear Sight Picture
The bottom-mounted SIG-LOC architecture allows for a longer focal length, dramatically reducing parallax and reticle distortion. Combined with a distortion-free aspherical glass lens, this results in an ultra-crisp, forgiving sight picture that enhances accuracy and target acquisition.
Rugged, Duty-Ready Construction
Housed in a durable 7075 aluminum body, the ROMEO-X features a fully enclosed and sealed optical system designed to withstand harsh recoil, impacts, and environmental conditions while maintaining consistent performance.
Efficient Illumination & Long Battery Life
The optic includes MOTAC (Motion Activated Illumination), automatically powering on with movement and shutting off when idle to conserve energy. A convenient side-load battery tray supports up to 20,000 hours of runtime and allows battery replacement without removing the optic or losing zero.
Optimized for Co-Witnessing
With the industry’s lowest deck height, the ROMEO-X supports standard-height iron sight co-witnessing. It offers 15 illumination settings, including three dedicated night-vision modes, for adaptability across lighting conditions.
Built in the USA
Assembled in the USA and fully backed by SIG SAUER’s Infinite Guarantee, the ROMEO-X SIG-LOC is engineered to meet the demands of the most discerning shooters.
