    Does anyone know the actual action lengths (in mm. or inches) of the 6 Sako 85 actions? I'm trying to determine what scopes will work (with respect to ring spacing) with the differing action lengths. The designations that Sako uses are XS, S, M, SM, L, and XL.

    I guess the most useful measurement would be the length from end of the rear dovetail to the beginning of the front. IE the ejection port opening. Here's what I found: XS 57, S 74, SM 74, M 85, L 94, XL 94 millimeters. It's funny how in the promo pictures all 6 receivers are different lengths. Somebody has taken little bit of artistic license.

    Thanks for that P04R. Is the attached picture the one you're referring to? I wonder whether the lengths of the receiver ring and bridge are the same for all action lengths (with only the ejection ports differing in length)? Hard to tell from the picture attached, where it looks as if all but the XS receiver ring and bridge lengths might be the same.

    That's the picture, though I remember seeing one where the step up is perfectly equal for all six. I might remember wrong.

    Looks like the rear bridge varies in length but I'm pretty sure the rear dovetail is always the same since the optilock basemount always covers the whole dovetail. Front dovetails are all the same with the exception of XS.

    Yes, I think you're right. The rear tang may be a bit longer on the L and XL actions, but the length of the dovetail appears to be pretty similar for all but maybe the XS action.
