Agree, especially if the claims made by Mr. Borden are true for which I have no reason to doubt that they are not true. I never imagined how much the firing pin design can contribute to precision shooting.With the rising cost of components and barrels, the price of a custom receiver is less and less significant by the day.
It's so much easier starting out with something that is at least capable of meeting your standards than trying to fix something to meet those standards.
