If I purchase a Thompson Contender/Encore from a gun shop as a rifle and or muzzle loader. Can I legally convert that rifle into a Thompson Contender/Encore Pistol? And by converting it I mean, can I legally install a pistol barrel and pistol grip and shoot it. Than if I decide, convert it back to rifle?
Or is a rifle frame only allowed to be a rifle?
