Sig Sauer ROMEO-RS Compact (RMSc) Red Dot - Circle Dot or 3/6MOA Dot

Featuring a hybrid design with a skeletonized steel chassis embedded in a durable polymer housing, this optic is built for rugged reliability without adding unnecessary weight.

With a distortion-free aspheric glass lens and ultra-efficient LED emitter, the ROMEO-RS delivers a crisp, clean sight picture with up to 8 brightness levels. Choose from multiple reticle styles, including a precise 3 MOA or 6 MOA dot, or a fast-acquisition circle/dot combo—available in both red and green.

A side-mounted battery tray (CR1632) makes swaps easy without removing your optic, and the large side control button ensures fast reticle adjustments even under pressure. Thanks to MOTAC™ (Motion Activated Illumination), the ROMEO-RS powers on when you move and off when you don’t, preserving battery life for up to 20,000 hours of runtime.
