No, those are the vintage Sako mounts which are no longer made and came in 1" size only. They are excellent mounts and have windage adjustment, which the Leupold mounts don't have. Your best bet for 30mm. mounts, in my opinion, would be to avoid the
two-piece Optilocks, which have a separate base along with the rings and are unnecessarily heavy, and instead use either (a) the 30mm Leupold Ringmounts or (b) the 30mm Sako Ring Mounts which are one-piece (see below). My preference would be the Sako Ring Mounts. They're available from Stoeger Canada. The Leupold and Sako ring mounts are made to slip right onto the Sako tapered dovetail machined into the top of the receiver and so eliminate the need for separate bases. All Sako rifles from the earliest L46 to the 85 (but not the 90) have this tapered dovetail, an excellent scope-mounting feature.
Note. Just to avoid confusion, what I've recommended are labelled Sako
Ring Mounts. These are one-piece mounts that attach directly to the Sako tapered dovetail. They are different from the Optilock
Rings that require Optilock bases and are part of the heavier two-piece Optilock system.
