    Recently I purchased a Sako L61R in .30-06. What a gorgeous rifle! To scope it I purchased a new Leupold VX-3i 3.5-10x40 scope, and solid Sako rings (Sako Optilock Blue 75/85 1" Low Ringmounts S1701900). When I first mounted the scope, I mounted the forward ring all the way to the rear adjacent to the ejection port, as seen here:

    When I went to group the rifle, the POI was feet to the left at 25m. I dialed the scope POI right as far as it would go, and still didn't pattern on paper. At this time, I began to research this issue (mostly via threads on this forum), and found that I could shift the POI to the right by moving the forward ring to the center of the front mount. I patterned the rifle again, and now was at least on paper, but still to the right. A second range trip with my scope mounting tools packed along produced this configuration, which is where it is right now:

    The scope bases are now as far apart as they can physically be on the scope. At 25yd, the rifle is still patterning 2" to the left of the bullseye. More importantly, the gun does not hit paper at 100yd even in this configuration, and even when I aimed past the far right of the target stand. As far as I can tell, one of three geometric conditions may exist:

    The scope is more or less parallel with the barrel, but offset to one side (unlikely).

    The scope is cocked in windage across the barrel.

    The scope is cocked in windage away from the barrel.


    Another option is that the scope is defective and needs to be returned.

    Hopefully, when I post this, the problem will be obvious to some users of this forum and I will just need to re-mount the scope and go. Any ideas?

    I have a nasty suspicion that this particular style of ring is not compatible with older Sakos. There have been previous complaints posted on the forum of one-piece Optilock rings not lining up on L and A series rifles. The packaging and online catalog information from Sako and Beretta list these rings for the 75 and 85 models and do not mention the older guns. This is in contrast to the Optilock bases, which are listed for specific 75/85 variations and L-series actions. I don't know what the difference could be; I don't own a 75 or 85 and I've never worked with the unitary Optilock rings. It's widely believed that all Sako dovetails are the same, but in fact there are variations. Full-coverage bases for the L-series guns, such as those from Redfield and Conetrol, come in different versions for the L461/L579 actions and the L61R.

    Here's a test you can try to get some information on the problem. On the back of the front ring, draw a vertical line from the lowest point of the scope to the base. Then draw a line down the precise center of the dovetail base. Use something like a white or yellow carpenter's pencil that will make a visible line but will not mar the surface. Then slide the ring forward and back on the dovetail and see if the center line of the scope lines up at any point with the center line of the dovetail. The rear base should be centered because of the alignment stud, but you can check that by finding the center of the scope and determining if that is in the center of the dovetail when the clamp screw is snug.

    I hope this helps you figure out what is wrong. I personally use only original, old-style Sako rings on L-series rifles, except for the occasional set of Conetrols on a custom. The Redfield-type mounts work, but the rings may require lapping. And several of our members swear by the one-piece Leupold rings, which share the same general design as the one-piece Optilocks but do fit the older guns.

    Thank you for the advice. If it's a problem with the rings, I can live with that. Buy a new set of rings, zero, and go. Maybe some nice chap here would even buy the rings I have off me, heh.

    Just to make sure that if/when I do buy another set of rings, could you direct me more precisely to some you know will work with the L61R? Do you have a Leupold catalog number or something like that? The old-style Sako rings are not made any more? Or they're a different model number than what I have?

    The old-style Sako rings have not been made for many years. They are usually available, in excellent condition, from SakoSource, a sponsor of this forum. Who knows, he might even take your rings in on trade. The old rings aren't cheap, but they work, are fully windage adjustable, and have a certain cachet of authenticity about them. You can also find them on eBay and Gunbroker, with varying prices, conditions, and degree of honesty in the descriptions.

    Someone else will have to jump in on the specifics of Leupold rings for Sako. I don't like or use them, so I'm not the one to ask. Hopefully Paulson or Stonecreek, both of whom do use Leupold rings, will add their expertise.

    And by the way, that is one gorgeous rifle. I've never seen borderless checkering like that on an L61R - the checkering on most has borders, all too frequently too wide, too deep, and sloppily executed. Could that rifle have been refinished and recheckered?

    What's his U/N here, if you don't mind? I can't seem to tag "SakoSource".

    As long as the Sakos are semi-reasonable in price, I'll probably take that route, if necessary.

    I've seen no evidence that it was refinished (proofs and markings all look normal to the other Sakos I've seen - no "bubba marks"), but if the smith was good enough I probably wouldn't be able to tell. If memory serves, I dated it to 1973, and put some extra effort into getting a pre-Garcia gun, so it is a "nicer" grade than some of the other L61Rs. Little extra patience and a bigger budget, because I want to hand this down to my son when he's old enough to say 'cat' properly, at least. ;)

    Or you can click on the ad at the upper right of this page. It rotates between Sako Source and Classic Arms Journal.
    That may explain the checkering. The top surfaces of the dovetails appear to be smooth, not checkered. There were some guns made in that time frame that were a bit different, a model 72 or 74, I forget exactly, but it was a little different from the usual production and I distinctly remember that the dovetails lacked checkering.

    Thank you very much!


    The dovetails are checkered. Let me get a photo.

    OK, I see. Maybe someone who is more familiar with rare variations will be able to explain that checkering.

    Grem.....

    Have you confirmed that the scope reticle was mechanically centered, within it's adjustment range........before mounting in rings?

    Just a thought.

    Not sure precisely what you mean.
