It works i hope for a long time but it is chicom. - Vortex Defender-CCW Enclosed Solar Micro 1x20.2mm Reflex Red Dot Sight

Easy install. All the things necessary. In package. Dot has some star burst , it ok as long as it doesn’t get worse. The only thing I really don’t like is when out side you draw weapon and the dot is slow to materialize. Why it does is beyond me. In doors it is battery comes on fast. Outside slow.
