When you close the bolt the firing pin releases about 50% of the time. If you manage to get the firing pin to lock and put the safty on when you take the safty off it will fire the gun. I have taken the trigger off the gun and the firing pin out of the bolt and checked everthing to make sure it was clean and no burrs on any parts and the only thing I found was the bolt side of the sear(not sure if sear is the right name, the part that releases and holds the firing pin in the ready position), that you can see with the bolt removed, the chrome is a little bubbled up and coming off right were the firing pin and sear engage each other. Do you think that might be the problem? and if so whats the proper name so I can order one. Thanks for any help.
