I got a new to me 223 barrel and bolt head. I installed them and test fired it and here's result.


I am measuring the firing pin protrusion at .065. Is there any way to shorten it on these firing pins without a file?


I'm measuring the difference of the firing pin hole and the firing pin to be roughly .003-.005. Not sure what it's suppose to be. It's not an exact measurement. With the pin laying on one side of the hole I used the calipers to push it to the other side and measure the difference.
