I bought this M70,(49 30-06 standard)cheap, for an any weather hunting gun. When it is blowing snow or rain, I like having iron sight capability when hunting anything important. Ideally, I would like to find a side mount that matches these holes, so I can keep the peep, and see under the scope. I am having trouble finding any of the vintage side mounts with this hole spacing. I was hoping one of you guys would be able to recognize the hole spacing. There are 4 holes, .970 apart. I have looked at a bunch of pictures, but haven't found any that look close. It would be nice to know what brand to look for.

Pachmayr and Weaver are the only ones which come to mind that use four screws, but they don't match that pattern. However, Griffin & Howe mounts can be had with blank bases which can be drilled to fit any hole pattern.

I don't think you will want to leave the receiver sight arm in place while using a scope, however. The advantage of a side mount is that it allows a scope to be mounted low enough so that the line of sight remains the same as with the receiver sight. A "see through" mount raises the sight line to the point that the face is no longer in firm contact with the stock.

You would need to replace the Williams receiver sight with something like a Lyman 48, which has a slide which can be removed and replaced without a change in zero.

Here is a pre-War G&H Springfield sporter with the type of high mount you are referring to.



This is the more modern version of the same mount, with the scope mounted low enough to take full advantage of the side mount's characteristics.

It used to be that Weaver produced a base for
their sidemounts that had no holes drilled, this allowed
one to drill the holes in the base to match any existing
holes in the receiver. This maybe the most expedient
solution to your problem.

The mount may not have had 4 screws,it was common to use taper pins,in addition to a couple screws.This made a more solid mounting that would not move.It is possible the tapered holes were tapped for plug screws.There might be signs of this,inside the action.Taper pins are avaliable is different sizes,so one of the blank bases mentioned above can be installed with two screws and two taper pins(sized to clean up the old holes).Of course this is if taper pins were used, originally.

This may have been what I needed? I've never heard of Kruzell mounts. This lady has a bunch of other old gunshop inventory, maybe I will ask if she has any more, and to measure the holes. If I could find a Weaver side mount blank, I would go that route. I have a couple sets of Weaver Pivot mounts for M70's, so if I don't come up with a side mount before fall, I will just use them, and the bbl. sight.
Thanks everyone for their help.

I don't know why this didn't occur to me before, since the receiver sight is a Williams, but Williams also made a side mount and it used a base with four holes. I'm sorry, I don't know what the spacing of the holes is.
