I've had an itch for a 9mm AR for a hot minute now and finally took the jump, I'm going to register it as a pistol for now as I had most the parts sitting around but I really wanna sbr it, how the hell do I do it, I don't want the atf to shoot my dog. If you dm me I'll give you my number, I'm not too good at remembering to check on here. Also if anybody has experience with making a can out of those solvent traps please let me know too, I'm 20 so I can't buy a new surpressor I can only make one (yes I would tax stamp that legally too)
