Ok, so here's the deal. I've got a Mossberg 835 ulti-mag that has been for sale for quite some time now, no offers or interests in it. So I may as well keep it. I'd like to turn it into a tactical type shotgun. Any ideas on where or if I can find a shorter barrel, different furniture or other accesories for it ? I've checked quite a few websites and have found nothing for it. Any ideas or help would be greatly appreciated.
