Do NOT waste your time on that rear sight from Jeff's Outfitters, it isn't any good. I bought 2 sights from him, one being the express sight and had to send the express sight back. In all fairness to Jeff he told me the sights weren't top quality before I ordered and he promptly gave me a refund. I would buy from him again. The other sight was the repro Winchester tang sight which I found acceptable for my purposes, that is a temporary rear sight to work up some loads with. Save your $60 to put toward something better.
