SIG Sauer Electro-Optics ROMEO-RS Compact Open Reflex Sight (Shield RMSc) — 2 MOA Red Dot / 32 MOA Circle
The SIG SAUER ROMEO-RS Compact is an open reflex pistol red dot built around a hybrid reinforced-steel chassis with a high-strength polymer housing and a molded glass aspheric lens for a clean, distortion-free sight picture. The Compact version uses the Shield RMSc footprint.
This model features a selectable 2 MOA red dot / 32 MOA circle-dot reticle (circle/dot, dot-only, or circle-only), 8 brightness settings, and MOTAC motion-activated illumination. A side-mounted CR1632 battery tray allows battery changes without removing the optic from the slide.
