SIG Sauer ROMEO-X Pro Open Reflex Green Dot Sight 1x24mm 6 MOA Green Dot Reticle, Black – SORX1090

The SIG Sauer ROMEO-X Pro Green Dot Sight is a premium open reflex pistol optic designed for optic-ready pistols using the SIG PRO / DeltaPoint Pro-style footprint. Built with a CNC-machined 7075 aluminium housing, ultra-low deck height, side-mounted CR1632 battery compartment, and MOTAC motion activation, the ROMEO-X Pro delivers a fast, durable, low-profile optic solution for compatible pistol platforms.

This SORX1090 model features a clean 6 MOA green dot reticle, giving users a larger, highly visible aiming point for fast target acquisition. The optic includes 15 illumination settings, including 12 daylight and 3 night vision-compatible settings, with up to 20,000 hours of runtime from a single CR1632 battery.

Designed, developed, tested, and assembled in the USA, the ROMEO-X Pro includes a distortion-free aspherical lens, patent-pending beryllium copper flexure arm, open emitter design, 10mm-rated construction, IPX7 water resistance, and low deck height for co-witness with standard-height iron sights on compatible pistols. SIG lists the ROMEO-X Pro as suited for optic-ready P320, P226, and P229 family pistols.

Compatibility Note: The ROMEO-X Pro uses the SIG PRO / DeltaPoint Pro-style footprint. Always confirm your slide cut, mounting hardware, and adapter plate requirements before installation.
