Kelby's 20 MOA Ring Spacing

[Terry]

I bought a 20 MOA Base/Rings setup from Kelby's a few years ago.
There was a specific distance between the rings to get 20 MOA.

Anybody know what that may be?

This is a Kelby's product.

If it's a one piece base, then ring spacing doesn't matter, the slant is built into the base. Two piece bases are simply two pieces of a slanted rail so again the slant is built in. Assuming use of two identical rings.
Now if you are using something like Burris Signature rings that can have cant in the inserts, spacing becomes somewhat important. Go to Burris's website, the have a chart or equation for calculating distance.
