I was at my LGS last week where I do my NFA items purchasing. Were discussing a couple of form 1s I have efiled and pending. Now I pretty much know what the words out of a GS salesman's mouth are worth, but I am going to put out for comment what he said as I admit being pretty ignorant on NFA rules and regs. His statement was that if your are submitting a form 1 to construct a SBR that your are building from a receiver that has never been built and is not registered as a rifle that you do not have to have the receiver engraved. Only if you are converting an existing rifle to a SB configuration does it need engraving. Is he correct?
