Title: Need help finding scope base.
Post by: Pete112288 on February 08, 2025, 01:50:09 PM: So my dad got a new scope for his rifle and when I went to mount it for him I have come to an issue. The new scope he got is a 34mm tube, and be bought new rings for it. His old scope was a 40+ year old bushnell with weaver rings.
The new rings need a bigger cross slot in the base. It needs the size slot like picatinny rails have, not weaver style.
The bases on the rifle were 2 #11 weavers.
The rifle is an old 1917 Enfield 30-06 that had no original base mount holes and was drilled and tapped later. So I am having an extremely difficult time finding a new base to go with his new scope and rings.
The hole spacing is 2 holes in front and 2 in rear, they are .504 or so apart, allowing 2 piece weaver #11s. The hole spacing between the rear hole in the front and front hole in the rear is 4.20"
I can't seem to find anything that matches up that will give a larger cross slot.
Please, any help is a giant help.

If, that is, I am understanding your issue correctly.

I think you can even get blanks and make your own holes.

Geometry and elevations where it meets the receiver would be key.

The cross slot does take recoil.
