Sig Sauer ROMEO-X Compact Red Dot Sight (Shield RMSc) – Red Circle Dot Reticle
The Sig Sauer ROMEO-X Compact is a 1x open-emitter pistol red dot built on the Shield RMSc footprint with a top-mount design and ultra-low deck height for standard-height iron sight co-witness. It features a CNC-machined 7075 aluminum housing, distortion-free aspherical lens, and intuitive side buttons for brightness control.
Illumination includes 12 daytime settings plus 3 night vision settings, with MOTAC (motion-activated illumination) and a side-loading CR1632 battery compartment to allow battery changes without removing the optic. The installed reticle is a red circle dot.
