When the action is fast, target acquisition and accuracy are paramount. Our miniature, open reflex ROMEO1 sight withstands the punishment of deployment while maintaining a confident zero. TruHold™ twin adjustment springs provide a lock-less zeroing system that is on-target shot after shot. Designed to fit the most popular pistols, or you can mount it low and co-witness your iron sights on a SIG SAUER® pistol with a custom-machined slide. CNC-machined from a solid billet of Magnesium for lightweight strength. The molded aspherical lens is bright and distortion free, and the red-notch coating ensures a brilliant red dot. Manual brightness controls with our MOTAC™ (Motion Activated Illumination) system remember your last setting after powering off. Powered by a top-loading battery so you never have to lose your zero.
