As Icebear says, the 2.5-8 Leupold is just barely long enough for a long action Sako. I have some original Sako extension ringmounts in medium height, which is appropriate for the 36mm objective bell. The front mount is the extension mount and will turn either forward for a long-bodied scope (not many of those around anymore), or rearward for a short bodied scope. I actually have two sets of these and would sell one. If you're interested start a Private Conversation with me.
