Sig Sauer ROMEO-X Compact 1x24mm Open-Emitter Red Dot Sight (Circle Dot, Shield RMSc)
The Sig Sauer ROMEO-X Compact is a micro-compact pistol red dot built around a distortion-free aspherical lens and a CNC-machined 7075 aluminum housing. This model is designed for the Shield RMSc footprint and features an ultra-low deck height for co-witness with standard-height iron sights.
It uses a side-loading CR1632 battery to allow battery changes without removing the optic, and includes MOTAC (motion-activated illumination) with multiple brightness levels including night-vision settings.
