I sent my Uplander back to Stoeger (loose rib...they have great customer service, by the way) and they called to tell me that they couldn't fix the rib and would send me a new shotgun. I told them I'd rather get just new barrels, as the wood on mine was very nice. They told me they couldn't simply replace the barrels, as each receiver and barrel set is matched. Look at the serial number-it's on both the receiver and the barrels, indicating that they are a matched set. I'm sure if you sent them your receiver, they could match up another set of barrels. Give them a call or send an e-mail. I found their support staff very helpful.
