Sig Sauer ROMEO-X Pro 1x24mm Open-Emitter Red Dot (SIG PRO / DeltaPoint Pro Footprint)
The Sig Sauer ROMEO-X Pro is a full-size open-reflex pistol optic built around a CNC-machined 7075 aluminum housing with a distortion-free aspherical lens and an ultra-low deck height for co-witness with standard-height iron sights.
Controls are push-button with 15 illumination settings (12 daytime and 3 night vision compatible). Power comes from a side-loading CR1632 battery to allow battery changes without removing the optic, with MOTAC motion activation and up to 20,000 hours of runtime. The ROMEO-X Pro is 10mm rated and IPX7 water resistant.
