The SIG Sauer ROMEO-X Pro Green Dot Sight is a premium open-reflex pistol optic on the DeltaPoint Pro footprint. The green reticle is perceived as brighter by the human eye in many lighting conditions, making it pop fast against varied backgrounds.
This model runs a selectable 2 MOA dot / 32 MOA circle reticle, with MOTAC + MAGNETAC activation, 15 brightness settings (3 night-vision), a top-loading CR2032 tray and IPX8 sealing.
