Built for shooters who demand speed, clarity, and confidence, the SIG SAUER ROMEO-X Enclosed Pro Reflex Sight brings rugged performance to optic-ready pistols with the DeltaPoint Pro footprint. Its fully enclosed, sealed 7075 aluminum housing helps shield the emitter from dust, rain, and hard use, while the aspherical glass lens delivers a crisp, distortion-free sight picture for fast, precise target focus.

Motion Activated Illumination (MOTAC) powers the optic on when it senses movement, helping deliver up to 20,000 hours of runtime on a single CR1632 battery. The side-loading battery compartment makes replacement simple without removing the optic or losing zero. With 15 illumination settings, including 3 night vision modes, the Circle Dot reticle gives you flexible aiming for daylight range work, defensive carry, and low-light conditions.

The ultra-low deck height supports co-witness with standard-height iron sights, giving you a streamlined setup that stays ready when it matters most. Finished in Flat Dark Earth, the ROMEO-X Enclosed Pro combines compact size, dependable durability, and refined aiming performance in one serious pistol optic.
