Hi all, I have a quick question about the future of AR-15's and other "assault rifle" types. I'm a little worried about being able to buy one in the future with the new President, yet I'm 23 can't afford one at the moment. I was thinking about buying just the lower (or is it the upper?) and that way I technically own an AR-15 and probably still buy the rest to build it legally even they became banned. Am I being overly paranoid about this, and if I'm not do you see any reason why this wouldn't work?
