I've got a Mossberg 930SPX that I bought a few years back and I recently noticed the front sight is canted. After some research apparently this was a problem with the early models. I called Mossberg and they said I would have to ship the entire firearm to them so they could make a decision on it, because I waited so long to report the issue. I know I should have looked at the gun, I fired it probably 10 times then put it back in it's box for a few years. Anyway I'm wondering how I should handle this, is it worth sending the gun into Mossberg, and will they take care of the issue or am I screwed for waiting so long to notice and correct the issue? I've never had to service a firearm under warranty so this is a new experience.
