Sig Sauer ROMEO-X PRO Open Reflex Sight (6 MOA Green Dot, DPP Footprint)
The Sig Sauer ROMEO-X PRO is a 1x24mm open-emitter pistol red dot built around a low-deck design for standard-height iron-sight co-witness. It uses a CNC-machined 7075 aluminum housing with an aspherical glass lens, MOTAC motion-activated illumination, and a side-loading CR1632 battery compartment to allow battery changes without removing the optic.
This unit features a 6 MOA green dot reticle with 15 illumination settings (12 daylight / 3 night vision) and up to 20,000 hours of runtime at a medium setting (dot only). Designed for optic-ready pistols using the DeltaPoint Pro (DPP) / SIG PRO footprint and rated for 10mm.
