I put a 7.5" upper on my Colt SP1 and when I went to re-register it, the lady at the CFC told me there was no FRT for a 7.5" AR-15, so she won't register it without having one created. I'm sure I'm not the only one who owns one. Does anyone know the FRT for these? Please Pm me if you do. Thanks in advance.
