I have a indoor range in my garage. Want to shoot at night or darkness? Go buy a cheap UV flash light form Walmart. Paint your target with some glow paint, or most any paint and bingo. Works great. I also have one set up outdoors in my back yard. Also if you want some quick easy and cheap back stops, get a Walmart bag, fill it with some old clothes and you can place them every where, hang them in trees, in the house, garage, etc. Light weight and can handle any fast moving pellet.
