i bought a suppressor from a local "Armory" last may and still have not received my paperwork. is this normal or has anyone else had the same prob with this "Armory"? the dealer wont give me any info and is not being helpful. they wont give me the serial number cause he says its his policy not to give the number out. the atf cant tell me anything until i get it. i dont know what to do. can somebody help me out???? please?
