If I had a kit in form of a bag of parts, no formed receiver yet, can I have a shorter than 16" barrel and the muzzle extension which will bring to 16" length and be ok as far as 'constructive possession'?
As I see it, if the receiver is not formed yet, should be ok. because I need to populate the barrel before permanently pinning/welding the extension....right?
once that step is complete, the barrel will be >16" and I can go about building the receiver....?
