Sig Sauer ROMEO-RS Compact 1x24mm Open Reflex Sight (Shield RMSc Footprint)
The Sig Sauer ROMEO-RS Compact is a pistol-mounted open reflex sight built around a reinforced steel chassis molded into a high-strength polymer housing, using a premium aspherical glass lens for a low-distortion sight picture. Illumination is controlled via a large side button and features MOTAC (motion-activated illumination) to extend battery life.
This unit includes mounting screws. The side-mounted CR1632 battery tray allows battery changes without removing the optic from the slide.
