When you need fast and accurate target acquisition, choose the Sig Sauer Romeo3 Mini Waterproof 1x25mm Reflex Sight to maintain a consistent zero shot after shot. The compact size of these Red Dot Sights from Sig Sauer allows low or co-witness mounting. Each unit is CNC-machined from aircraft grade aluminum for lightweight strength. The Sig Sauer Romeo3 Mini Fogproof 1x25mm Reflex Sight is equipped with MOTAC (Motion Activated Illumination) to power off when the unit isn’t moving to save battery power, yet still remember your last brightness setting next time you turn it on. Spectracoat lens coatings and 11 illumination settings combine to give you ultra clear daylight and night vision images from the Sig Sauer Romeo3 Lightweight 1x25mm Mini Reflex Sight.
