Sig Sauer ROMEO-X Compact 1x24mm Red Dot (Shield RMSc Footprint)
The Sig Sauer ROMEO-X Compact is an open-emitter pistol red dot built around the Shield RMSc (compact) footprint. It features a CNC-machined 7075 aluminum housing, distortion-free aspherical lens, and an ultra-low deck height for co-witness with standard-height iron sights.
This optic uses a side-loading CR1632 battery so the battery can be replaced without removing the sight from the slide. It also includes MOTAC motion activation, 15 illumination settings (12 daylight/3 night vision), and up to 20,000 hours of runtime.
