Sig Sauer ROMEO-X Pro 1x24mm Open-Emitter Red Dot (DPP/PRO Footprint)
The Sig Sauer ROMEO-X Pro is a pistol-mounted open reflex sight built around a 7075 aluminum housing with a distortion-free aspherical lens system and an ultra-low deck height for co-witness with standard-height iron sights. It uses a side-loading CR1632 battery and MOTAC motion-activated illumination with 15 brightness settings (12 day / 3 night vision) and up to 20,000 hours of runtime.
Designed for optic-ready pistols using the DeltaPoint Pro (DPP) / SIG PRO footprint, the ROMEO-X Pro is 10mm rated and features SIG’s patent-pending beryllium copper flexure arm adjustment system for windage/elevation corrections.
