Hey all, I'm new to the MD shooters forums and I have some questions regarding the legality of owning an 80% AR lower. I know it's possible to order them, but a local gun shop told me that unless I'm a licensed gunsmith or FFL dealer, that I cannot finish the machining on an 80% lower to make it into a "firearm" . The lady said it was illegal. But I've heard that as long as I finish the lower, with no intention of selling/giving it away, and use it only for my personal use, that I'm perfectly fine to do so..so here I am asking y'all about this! Thank you in advance for any advice
