Bolt help on AA upper - Ludeconduct - 07-08-2014
I haven't had this long and decide to take bolt down and clean it. When I took it out I noticed the firing pin seemed to be binding on something. The firing pin rubs the extractor pin, tried replacing firing pin did not help. Ended up grinding just a slight amount out of extractor pin to create a clear passage for firing pin. Is there something that normally causes this? The extractor and pin hole placement look correct. Thanks

Is the firing pin hole centered?

Yes it is and with the pin shaved the firing pin sits dead center of the hole before it was pushed to the side.

Always a burr to be dealt with, part of any machining process . Check that firstly, mine still hits off center , to the rt., just a tic.
