Firing pin assembly.
There is a grub screw on the underside of the bolt shroud which ensures the firing pin spring is kept in place.
On mine someone has tried to drill out the grub screw and failed.
I had taken it to a smith who could not drill out the grub screw as he said it was hardened as hard as the drill.
Talked about spark erosion as well.
It is a small diameter screw.
I have been using the gun for the past 5 years with no problem
Should I try someone else or leave it?
