I bought a Buehler 1 pc. base mount on this from a gentleman on this site from TX- $70.00 fair price indeed. But I made a mistake, as we all do, and didn't specify if it was for a Pre-1964 M70 Long action, or a Short Action, as on the Featherweight series M70's in .243, etc. It won't quite fit on the 1952 M70 in .220Swift I now own. So, unless Mr. Buehler offers, along with the rings I also need for the 1" dia. Weaver V2x-9 scope I plan to use on this "woodchuck devastator", a scope base "extender", I have no present use for it.

Details:End flap on orignal period box is stamped--BUEHLER 1-piece MOUNTS BASE WIN M70 code- 70-s short. Pre 1963, as there is no Zip Code for Orinda, California-- With screws and original instructions, including Maynard's "pithy" note IF ALL ELSE FAILS-FOLLOW THESE DIRECTIONS Instructions for installing the Buehler Mount on undrilled receivers- 3 6-48 machine screws included and base is stamped BUEHELER Oinda Cal. 100% blue finish oal. I paid$70.00 for this, would like to get close to that if I sell it.

I may want a set of 2 pc. Buehler or Leupold bases for this same rifle, ditto 1" medium ht. matching rings. Please advise by return PMS on this website. RWTF

Fox,

The S (short) designation on the Buehler 70S base refers to where the front ring is located & has nothing to do with which action it was intended for.

The 70L base & 70S one piece bases have exactly the same hole spacing but the base is longer & moves the front ring about 0.8" farther forward to accommodate the turret position of a longer scope.

Either the 70S or the 70L will fit on a post war(non magnum length, ie. 300 or 375 H&H) M70 Winchester action that was factory drilled & tapped. In Post war Pre 64 M70's you only had the std. action & the magnum action.

Any chance your M70 Swift is built on a pre war M70 action or very early transitional post war action? If so it requires a different base for the prewar style action.

Fox,

No, that is not correct. The base is mounted using both factory drilled & tapped holes in the receiver ring & the rear of the base base should line up with one of the holes in the receiver bridge. If it doesn't I'm not sure what base you need.

There were a few very early post war M70 rifles referred to as "transition period" that still had some features of the pre war rifle & did not have the receiver bridge drilled & tapped from the factory. Normally the bridge would be gunsmith drilled & tapped for the pre war base. In a Buehler one piece base it would be a # 54.

I hope this helps.

BTW: to avoid confusing anyone, I previously referred to the long M 70 Buehler base that places the front ring farther forward as a 70 L but the actual Buehler # is 70 & again the shorter base that places the front ring farther to the rear is the 70 S. Mounting hole spacing is the same for both bases.
