Charles, there are a few guys who do work that prefer to not get known......
I am fortunate to use one such person. He is very meticulous in his machining. He loves working on oddball/challenging projects as well.
Unfortunately for the masses he prefers to remain anonymous.......
The hunt for true BR capable gun builders in Canada is always a challenge. When you find one that can do the work required to make a winner..... hold him/her dear to you.
