I don't want to hi-jack this thread but I have a question along the same lines that I keep getting different answers to. I want to own an SBR. Do I have to register the upper or the lower ? I initally thought that I had to register the lower since that is the serial numbered item. Then someone else told me that I have to register the upper because if I had more than one short upper, I could be charged with possession of an unregistered SBR since the upper could be attached to any AR I owned. By registering the upper, this would eliminate that problem. Then I was recently in a local dealers shop and he told me that I needed to register the lower and it didn't matter how many uppers I had for that registered lower, all I had to say is that I used them only on my registered lower and as long as they wern't found on any other lower, I was OK. Now this thread seems to imply that I need to register the upper since OLY wants this guy to send them a Form 4 for an upper.
So I have been back and forth, back and forth. ???????????????????????????
If you owned a registered machine gun, and ordered this same upper from Oly, I know you don't need to do a form 4 since barrel length isn't an issue with the registered machine gun. So why the hell would Oly want a form 4 for an upper ?
