On a positive note, Bud's already CALLED me directly and let me know that while they can't replace it since I already did a transfer on the weapon... Mossberg should replace the sight or barrel if necessary.
Bud's also told me that if for some reason Mossberg wants me to pay for shipping, just let them know and they will provide a shipping label for me at no charge... so that's cool. I've heard both good and bad about Bud's customer service, but I was definitely pleased with that.
I'll keep everyone updated on what happens.
