All I do is buy the correct size butler creek and cut a hole in it and screw the 50ft adapter into it. There are a couple of guys in this country who do a special mod where they remove the glass and mount it in an alloy collar..then into the butler creek, this makes it much lighter. Both my Leupold comps have this type which were done by a guy called Mick Tromans. Neil.
