Today my cousin took his ak74 out for the first time. On the first round he stopped, and said there was something wrong. The hand guard was cracked and missing pieces on both sides. The palm of his hand was bloody and powder burned. I'm not really sure what happened. When he purchased it we cleaned it and oiled the gun. He was shooting wolf military classic. When we had him bandaged up we inspected the gun and found hairline cracks in the barrel along the sides. The bore was free from obstruction, and I don't think it was a double charge. I don't know much about ak's, and I was just wondering if you guys had some ideas of what might have happened. Thanks for any help.
