SIG Sauer Electro-Optics ROMEO-RS PRO Open Reflex Sight (PRO Footprint, 1x)
The SIG SAUER ROMEO-RS PRO is an open reflex pistol optic built around a hybrid skeletonized steel chassis molded into a high-strength polymer housing, with an aspheric glass lens for a low-distortion sight picture.
This model uses a side-mounted CR1632 battery tray for battery changes without removing the optic, and features MOTAC (motion-activated illumination), 8 brightness settings, and 70 MOA of total windage/elevation travel. The ROMEO-RS PRO mounts on the PRO / DeltaPoint Pro footprint.
