Hello all, looking for your help on something. There is a sbr on gunbroker currently I would like to purchase, but make it into a rifle by adding the 16" barrel. All the barrels do is screw in and out so easy swap. I'd leave it as is, but an sbr is a no-go here in NY. Am I correct in thinking that all that is needed is the current owner just decertifies it, doesn't include the barrel, and now my ffl accepts it in their books as a rifle?
Something tells me this is gonna get complicated
Edit:
Receiver was purchased originally by itself, then the parts were added creating the SBR. This did not start out as anything but a bare receiver.
