Yes, it can be done and I just did it. Works great.
Can you elaborate? You do it by hand or in a milling machine or?
It was done with a milling machine.
I did mine as there was a slight crack in the ADL part of the stock. (it ain't no Mcmilan) I had no choice, and in this case pot metal would obviously be better.
Note, I have never had a problem with the metal BDL parts of a 700.
