RE: Show and Tell time!
Dave, I bought the mounts from Williams, but it is a T/C mount. I had bought the scope the summer before and hadn't gotten around to put it on my sons ( he got the Lep. I bought latter)Ruger so decided to put it on the plains rifle. No mods needed except to remove the rear leaf sight.
Works really well, has a screw to lock it in place if you want while hunting. But I have left the screw out when target shooting and the POI stays where it is set. Same with the removal for cleaning, when I put it back on it is the same as when I took it off.
