Holosun hs503c - Holosun Paralow HS503C Circle Dot Sight

I did not know if I would like this red dot, But it has turned out to be great. It has manual and auto features, solar powered and battery, you can keep it in auto turn on or off the large circle around the center dot if you want, easy to sight in. co-witness' the iron AR sights like advertised. light weight but built tough. And was at a great price. I will buy another one.
