On my 30-30, my rear site is cracked, can you repair the site or do I have to buy a new one. The site has 2 set screws to tighten onto the fork shaped holder, it slides onto it and you tighten it down. In between the set screws there is a crack. Winchester model 94 30-30 lever action Trails of Tears 1839. Also the previous owner popped out the medallian on the side of the stock and put his name on a different medallian, WHERE would I find an original one.
