Check ebay, Auctionarms.com, and Gunbrokers.com. I have seen them for sale on all of the above sites. If you find one, check the feed back of the person selling it and see if they are an honest dealer. Unless they are a real jerk, they will refund your money if you are not satisfied with the product.
I have bought a couple of barrels off ebay and had no problem. I have bought many guns off the Auctionarms and Gunbrokers site and only received two that had problems, one was returned with a full refund including shipping cost, the other one I negotiated with the seller and ended up buying the gun at a lesser price that I initially bid.
