The Sig Sauer ROMEO-RS Pro (Reinforced Steel) is a pistol-mounted red dot engineered around a skeletonized steel chassis molded into a high-strength polymer housing. It uses a molded aspheric glass lens and a high-efficiency point-source LED to provide a clear, distortion-free sight picture. The optic includes a side-mounted illumination control and a side-load CR1632 battery tray with security screw, and it features MOTAC (Motion Activated Illumination) to power the sight on with motion and conserve battery when idle. Designed and assembled in Tualatin, Oregon, the ROMEO-RS Pro uses an updated RX footprint PRO for industry-standard optics compatibility with enhanced recoil pin lock-up.
