Sig Sauer ROMEO-RS PRO 1x Open Reflex Red Dot (PRO Footprint)
The Sig Sauer ROMEO-RS PRO is a pistol-mounted open reflex sight built around a skeletonized steel chassis molded into a high-strength polymer housing. It features an aspheric glass lens for a low-distortion sight picture, a large side control button for illumination adjustments, and a side-mounted battery tray with a security screw so the optic can stay mounted while changing batteries.
This model uses MOTAC (Motion Activated Illumination) to manage runtime and offers 8 brightness settings.
