The rifle bolt had two malfunctions after firing it(6+ years ago) I took it to a gunsmith who I don't think knew much about military weapons( I had him look at an M1Carbine for me too. I knew more) He said I needed a new bolt because a clip broke off, and the bolt would not close properly if I fired it again. The rifle has set for quite awhile. Now, I've found a replacement bolt and started this thread. After taking the bolts apart as far as I could, and oiling them I'm finding both bolts work well in the rifle. I still need to find someone who knows LE's a little because I don't want the bolt coming back at me if I fire it.
