That's an interesting order. I have a Carlson's brand 28" vent rib for my 12 ga and it's an excellent barrel- probably the best aftermarket for the price. A quick search at MidwayUSA, where I bought it, shows they only sell 12 ga, as does Brownells and Cabela's. Maybe Google Carlson's info, shoot them an email? If they make such a barrel, I'm sure they'd be more than willing to sell one to you. Price wise mine was far cheaper than the Remington alternative
