Try this fella's, call first, Paducah Shooters Supply, 3919 Cairo Road, Paducah, Ky. 42001. Phone is: 877-772-3006. I have sent more than a few Remingtons back to them for repair, they are a factory authorized repair facility. We recently sent them a 710 that the trigger guard had busted off, (as you know that is an integrated part of the stock, nice design, huh?). Anyway, fully repaired, no questions asked. I have sent them 1100's, SP10's, a lot of different models. Not bad turn around time, not great but not bad.
If you bought the gun from a local dealer, they should be more than happy to ship it back for repair. I don't think Cabela's, Dicks or Academy will, but the smaller stores (like us) do it all the time. Contrary to popular belief, you can ship a firearm yourself to a licensed FFL dealer or repair facility. It does not have to shipped FROM an FFL dealer.
Good luck and after you get it fixed, see if you can find a good home for it, because it'll break on you again!
