Hi all i am very new to this and figured i can get some great advice from you guys. I was told that i can purchase a full auto upper receiver and attach it to an existing lower as long as i get the tax stamp first?!? i was wondering if that is true. I have seen full auto uppers for sale on a few websites and before i got to excited i wanted to know what the law was. Thanks so much for you help.
