Firing Pin Bore Unfinished
I'm glad I checked this bolt before needing it as the inner bore that the firing pin runs through was not machined. Brownell's made good and sent out a replacement that works. But I'm still disappointed these pricy components apparently aren't being quality checked. If you have one that you simply stuck into a repair kit I would dig it out and test it.
