My .22 target rifle's (Walther KKM International Match rifle) spring guide broke while I was cleaning the bolt. The guide has a U-shaped bottom end that fits around the rear of the firing pin, and one side of the "U" broke off. I reassembled the bolt with the broken part and it seemed to be in perfect working order. I tested it with a few dry shots and it seems to work all right, but I haven't tried firing a round yet. Does anyone know if this could become a problem?
