Off the wall question, i called the NFA/ATF guy, but he said i need one of the specialist's there. Anyone know if its is legal. Say i get a 10" bbl for the ar, and i have a 7" can in stainless. If i mount it and tig weld it i would assume that would be legal? I have a rifle i would like to dedicate to a suppressor and that would do it. It would void the warranty of the can but is it legal. but the overall lenght is legal sooo
