True, the Pro Hunter forearms are interchangeable with the standard Encore forearms, but there are several contours in each style. For example, the 24" barrels take a different forearm than the 26" barrels (but the 28" Pro Hunter barrels take the same forearm as the 26" standard encore barrels). And unless I'm mistaken, the ML forearms are different yet (ad I have no idea about the shotgun barrel forearms...)
