Remguy , I have an F Saddle Ring Carbine as well,missing both the ring and staple, but the staple was shaved off smooth with the side of the reciever like you'd shave your wiskers. I have been led to believe that the best way to punch out the cut off legs of each side of the staple is to centerpunch them and carefully drill out their centers to relieve pressure and drive them into the inside of the reciever. I don't want to drill too large of a hole, so if you have a drill would you tell me how large the holes are on yours? Thanx, Malcolm.
I don't own the rifle, it was in the Gun Library at Cabela's in LaVista, NE, yesterday (03/23/17). I was making my weekly pass-through of their used guns and ran into a Winchester 320 that I didn't need for $329, but when the Gun Librarian knocked it down to $249, it was an offer that I couldn't refuse.
