Exactly. Do like I said and problem solved. There are not a lot of "gunsmiths" here obviously.. This chiidt isn't that hard to understand. Guys want to make it harder than it is.

BTDT a couple times, and no, I don't use soda pop cans..

Before:

After: Fine tuning the bases:

Those were pretty close, but fit by hand. The next step is to epoxy bed the bases...
If you use an alignment bar, you won't even need to lap the rings.

Some of you guys are way overthinking this. Of course, I'm not a "gunsmith"... YMMV..
