Seems like good quality - Holosun HE515CT Micro Red Dot Sight

The optic is pretty good. The see through caps are so hard to open. i thought they were glued. The dot is adjustable and clear. I liked the quick release mount that is included. The battery pack is really hard to change but hopefully that will be many years from now. It needs a tool ( included micro Phillips screwdriver) to open the battery drawer. I like the anti glare honeycomb feature as these are shiny orange looking from the barrel end. I would recommend this
