The SIG Sauer Romeo-RS Compact is a pistol-mounted red dot sight engineered around a reinforced steel chassis molded into a high-strength polymer housing for durability and lightweight performance. An aspheric glass lens paired with a point-source LED provides a clear, distortion-free sight picture. The optic includes a side-mounted illumination control, a side-load CR1632 battery tray with a security screw, MOTAC motion-activated illumination and eight brightness settings.
