My daughter sent her 870 to get me to fix it. The extractor was so dry I thought it was only needing oil. When that failed to fix the problem I watched a video a young man made and he was explaining that you need to be careful when seating the barrel, cause if you are to rough you can break the ejector. Then i remember her husband telling me when he shot it last the barrel was so loose that he had to tighten the nut. Does anybody know where to get one or are the unobtanium? if it needs to go to a smith to get the part and he wants to fix it that's OK too. Thanks Mark
