Last night I took the Burris tactical rings and Weaver bases off the M70 I am building and put on Warne maxima bases and Seekins rings. 

The cross bar under the rings [0.112" x 0.195" were too big to fit in the cross slots in the bases [ .148" x 0.103"
I have hundreds of rings and bases, and started measuring. It is odd I had not seen this problem before.

I milled out the slots to be  wider [0.200"] and deeper [0.115"] with a number of passes with a 0.187" end mill.

As you can see from my sketches, the Night Force and Burris rings are not looking for trouble, but the IOR and Seekins are bad boys that want to beat up on poor little Weaver or Warne. 
But EGW is a big slotted base and has no trouble with IOR or Seekins.
