When I started to drill for a new stock bolt I got quite a surprise, the stock had a 1/2" cast on. Could not see through the hole because of the curve in the stock. That is why the original stock bolt was replaced with a 1/4 threaded rod which bent to follow the stock bolt hole. The stock was given the cast on after it left the factory as it is very difficult to drill a curved hole. So now I am trying to figure how to make a new stock bolt with that much cast on. If I drill a new stright hole there is a great chance of coming out through the wrist as it is very thin.
