Description
SIG Sauer ROMEO4XT-PRO Red Dot Sight answers the two things people ask of a duty optic: give me a battery I can buy in any shop, and put the controls where I can reach them. It runs a single AAA for 50,000 hours with MOTAC, and the illumination control sits on top of the optic — ambidextrous, and clear of a chest rig when the rifle is slung. The quad reticle gives four selectable aiming options in a MIL-spec rugged 1x20 mm body.
