Sig Sauer ROMEO-RS Pro Circle Dot 1x31mm Black

The ROMEO-RS Pro is a compact, pistol-mounted reflex sight engineered to provide the accuracy and convenience of a red dot in a reinforced steel footprint. It combines a skeletonized steel chassis molded into a high-strength polymer housing with a molded aspheric glass lens for a clear, distortion-free sight picture. The optic features a side-load CR1632 battery tray, a large side control for illumination adjustment, and MOTAC motion-activated illumination to conserve battery life.

Designed for compatibility with industry-standard PRO footprint slides, the ROMEO-RS Pro offers robust mounting strength via steel recoil pins and metal inserts for windage/elevation and mount torque. The optic is assembled in the USA and backed by SIG SAUER's warranty support.
