Re: New owner of Mossberg 464 SPX, however this sucks !!! >> From your description of the hammer binding up the bolt and action it seems that your course of action (return for warranty service) is the best and only way to go. If a receiver pin has sheared or whatever no amount of coaxing is going to remedy the problem. I understand your aggrevation and frustration. Please post a follow up, and DEMAND that OFM return your rifle with a detailed description of the problem plus what was done to correct it.
