Questions about rear lug Stabilizing Receiver Bolt hole

I'm sorry if I missed this in a previous thread.

Why is it that I notice on many rear lug inletted stocks(new & used, wood & fiberglass) that the hole for the Stabilizing Receiver Bolt going into the bottom of the rear lug has not been drilled out? Is it not always necessary to use it? Does glass bedding eliminate the need for the bolt? Is it never done on certain stocks(fiberglass)? Is it normally done after the receiver is bedded into the stock?

Thank you all in advance, I KNOW I'll find the correct answer here!

Its done after its bedded for alignment reasons. SAI doesn't drill and tap the lug I'm sure for two main reasons time/money, and the owner over torqueing it.

One must remember that there has too be enough meat in the stock too clearance the lug and the addition of bedding material, many slim/USGI stocks are that too thin under and around the receiver heal.

There are differences between the lug size, location and screw hole location in various commercial receivers. There are also differences in the design of the lugs, depth, etc. One size or screw hole location does not fit all. That is why the pillars are installed after the initial bedding is completed.
