I have a Bushnell Dusk to Dawn 1.5-4.5x32mm on my T/C Black Diamond XR and it works great. I would hate to guess how many shots I have put down range with this scope on. In fact the glass on this scope is very good quality. When I was hunting marsh/swamps I could no longer look down a game trail I was watching with my cheap Simmons Binoculars, but I could see down the trail at the end of the day with that Dusk to Dawn scope on it.
