I'm thinking about buying a Thompson Center Pro Hunter Pistol. I've done all the research on converting a pistol to rifle and back to pistol. ATF says it is OK as long as you start with a pistol and don't configure a SBR. So my question is, does anyone know for fact if I can buy a Pro Hunter stock, forearm, and rifle barrel and put them on the pistol frame? Do they fit? I'm trying to save some money and effectively get both a pistol and a rifle with one "firearm" purchase. I am assuming the frame is actually identical between the pistol and the rifle but don't know that for sure.
thanks,
