I have a problem with my 9200 jamming. It seems there is a guide pin in the barrel that the bolt rides on. It looks like the pin is shaved down and the bolt is jumping on top of the pin. I was told by a local dealer that Mossberg would probably fix it for free because of the lifetime warranty on their guns. I was wondering if anyone has had any dealing with trying to get warranty work from Mossberg and if they fixed the problem.
