At the range yesterday with my friend, we had a M1icon carbine bolt come apart after firing about 40 rounds. Prior to this happening, there had been no problems -- no misfires, failures to cycle, etc. By "bolt coming apart" I mean the extractor, extractor plunger and spring, ejector and spring all came off the bolt. Other than the bolt coming apart, we could find nothing wrong with the rifle.

My first guess is that the bolt coming apart is indicative of an overpressure problem, but I was wondering if wear on any of these parts or the firing pin could also cause this to happen?


Thanks in advance for you help.

Jim
