The SIG Sauer ROMEO-X Pro (FDE) Red Dot Sight is a premium open-reflex pistol red dot sight on the DeltaPoint Pro footprint, in a flat-dark-earth finish to match FDE pistols and builds. It runs a selectable 2 MOA dot / 32 MOA circle reticle (red) for both speed and precision.
A distortion-free aspherical lens, MOTAC + MAGNETAC activation, 15 brightness settings (3 night-vision), a top-loading CR2032 tray and IPX8 sealing make it a serious-duty optic.
