Re: SBR Lower with Different Uppers

I've been told, and correct me if i'm wrong, that you cannot attach a "rifle" length barrel (16" or more)to an SBR registered lower, hence once you do, it's no longer an SBR. That was on the AR15 forums. Said something like "once a rifle, always a rifle. Anyone know the answer for sure?
