I don't yet have clearance for NFA items so hopefully that will come soon, but I'm not sure if sbr'ing is going to be legit. I didn't get to ask that question just yet but general consensus at the moment is that it may revert back to pre-86 status if that is done. If I hear from the owner, I'll post but please let me know if you get a definitive answer as well.
