Sig Sauer Romeo-RS Compact 6 MOA Red Dot Sight

The Sig Sauer Romeo-RS is a pistol-mounted red dot built around a reinforced steel chassis molded into a high-strength polymer housing. An aspherical glass lens and a point-source LED emitter provide a clear sight picture and an efficient reticle. The optic uses a side-load CR1632 battery tray and a side-mounted illumination control for straightforward operation while preserving zero. The updated footprint supports common RMS/RMSc pistol optics cuts for secure mounting.
