Outdoor use! - SightMark Element MTS-Mini Solar 1x22mm Red Dot

I used this red dot at an indoor range and due to it being a solar powered dot, it was a little hard to see. I think if I was outside, it would have worked a lot better. I think this is a great red dot to use outside, but if you are mainly going to be using it at an indoor range, I would think about it. I would still recommend it to be purchased if you are occasionally going to be using it inside, but I will admit it was hard to see indoors.
