Jim: Thanks for the prompt reply. I understand about the floating f i ring pin. What Iam saying is thatthe hammer is not striking the rear of the firing pin sufficiently to cause it to break the face of the bolt. It appears that the hammer is not contacting the firing pin at all. That said, any other suggestions? I should mention that i have converted quite a few Saigas and have built dozens of ARs, so I am not totally ignorant of firearms. However, this is the first 1919 that I have handled.
