Alrighty, I know that AR-15 pistols questions have been asked over and over again but I have yet to finda definitive answer.
Well then, here's my situation, I'm a 19-year-old resident of Maine. No legal problems and what-not so I can legally purchase rifles. Now federal law won't allow me to purchase a handgun from a dealer BUT since I'm older than 18 I can legally possess a handgun.
Could I in theory legally build my own AR-15 pistol? If I were to buy a brand new, unused stripped lower receiver and had it marked as a rifle, yet built it into a legal AR-15 pistol through a Model 1 Sales pistol kit, would I be violating any NFA or GCA rules? As far as I know if there is no way a buttstock can be attached and the receiver has never been used in a rifle it wouldn't be an SBR.
Any help would be greatly-appreciated. Thanks!
