Just because it is a C&R, does not relieve you of the need to get a stamp for that short barreled rifle. C&R covers most anything over 50 years old. I would not be surprised if the ATF came knocking at the owner's door this week.....chris3
No, some C&R stuff is exempt from from NFA tax and registration. For instance, Mauser Broomhandles, and Browning Hi-Powers that have the
original stock-mounting hardware and a holster/stock can have them and mount them without registering and paying the NFA tax. There are also several Winchester carbines on the list as well. So the NFA adding this one to the C&R exceptions list is not that unusual. It's more a matter that they were quick and helpful about it.
There's a reasonably lengthy list of exceptions on the C&R list. I recieved it with my C&R 03 FFL paperwork and law books. However, they're all things that would classify as SBR's, SBS's, or AOW's etc.
Machine Guns that are C&R can be transfered directly between C&R License holders, or directly from a NFA dealer, but you must still register it on a form 4 and pay the $200 NFA tax.
