Sig Sauer ROMEO-X Compact 1x24mm Open Reflex Red Dot (Shield RMSc Footprint)
The Sig Sauer ROMEO-X Compact is a micro-compact open-emitter pistol red dot built around a CNC-machined 7075 aluminum housing and a distortion-free aspherical glass lens. It uses a Shield RMSc (Compact) footprint for direct mounting on compatible optics-ready slides.
Controls are side-mounted with 15 illumination settings (12 daylight / 3 night vision), MOTAC motion-activated illumination, and a side-loading CR1632 battery compartment for battery changes without removing the optic.
