MM/WAR barrel?

So I want to get a hammer forge barrel for my P-rod and only see it listed on the MM site and not the WAR site. Does this mean that it is no longer available since MM is now WAR?

If not available from MM any more, anyone else make a barrel for the P-rod? Where are folks getting their LW P-rod barrels from? I want something that is plug&play/drop in/direct fit. Thanks!
