The FlipDot Patented folding Red dot reflex lens folds down flat when not in use. With a push of a button, it flips up and automatically turns on, while folding down turns the optic off. The 3 MOA Red dot is fully adjustable for windage and elevation. Integrated into the body is a backup rear sight and on the bottom of the lens frame is a backup front sight post. The FlipDot backup iron sights function when the lens is deployed in the up position, through the glass lens. The iron sights will cowitness with most of the Glock suppressor height sights installed on the slide (if equipped). Includes a Glock MOS compatible mounting plate, MOS mounting screws, 2mm optic spacer for RMR mounting applications, CR2032 battery, optics cover, and mounting & adjustment tools. Glock MOS compatible mounting screws are included.
