They make barrels for "all popular markers" so I imagine they would ... Are you absolutely set on a AA Stainless? They're heavy and IMHO over priced ... they're basicly useless after a break ... you need to squegy battle swab a pray if you want a decent shot after a break ... if you still want one ... go to
paintballbarrels.com
they don't have any AA Stainless barrels in stock but if you drop them an email and tell them what you're looking for they're really good about it.
