The FlipDot folding micro 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 co-witness 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. System turns off when folded.
