I have an old 30/30 with a Weaver scope and Weaver mount that you can flip the scope out of the way to use open sights. I know out dated, but that's what I have always used and am comfortable with. When it get's too dark to see through my scope I simply flip it out of the way and hunt with open sights for another 20 minutes or so. My cousin has been trying for a while to find this type mount with no success. I looked and am not sure Weaver still makes them. Does anyone know where we could find them?
