The DeltaPoint Micro is a fully enclosed, low-profile red dot sight designed specifically for concealed carry and personal defense. Mounted directly to the rear sight dovetail, the DeltaPoint Micro sits at the same height as factory iron sights and aligns the red dot with the front sight, giving you faster target acquisition and improved accuracy. With eight levels of illumination, you can adjust the brightness of your red dot to match current conditions. Fits Glock.
