I briefly ran mine in the older AICS AT chassis while waiting for the Manners stock. It worked fine, though the 26 inch sporter weight barrel looked silly. If you want to do it and look good get a fat barrel, perhaps even consider a Proof Research barrel.
I've run one of the older MF (S/N 52) actions in an AICS 2.0 folder and it worked just fine. I wouldn't think there would be any difference in the bedding block portion that would affect it mounting solidly and repeatably.
