I thought I answered this this morning but....Installed it and now my firing pin does not move freely when I press the safety down. Re-installed stock and it works fine. Is there anything I can do to fix this?
This won't cure anything. The problem is that the spring is rubbing on the channel liner and preventing the firing pin from moving during the test.+1 on running rounds through it. If it functions fine leave it. Alternative: clip one or two coils off.
