No, they arent interchangable and if I remember right (%ts been a while since I have done anything but rare and occasional shooting with a bolt gun) the older non accu-trigger equipped actions cant be retrofit. There should be smiths outthere capable of doing that conversion but Id bet the price would be better for just buying a new rifle. The accutrifgger is, however, a fantastic piece of gear. If a company rings something to market and every other manufacurer quickly copies something similar, there is a reason. I have a rimfire with it, and absolutly love it
