that is the website smith & wesson directed me to cuz they didn't have the part in stock I was looking for, but that company was also out of stock. Midway had it and the part is supposed to be here on Monday. I don't know what all the scope mount will fit for the 586 but if anyone wants it they can have it. What it currently was on is an older S &W model 586 6 " bbl and I believe it is an "L" frame revolver with a straight tang. The scope mount says Burris on it and it mounts to the top of the frame without the rear sight assembly in place. Let me know if you want it and you can either pick it up or for a couple bucks I can ship it.
thanks !
