Re: Carry paperwork with NFA weapon??
Congradulations on having an M-14. I am enviuos of you, but I personally wouldn't have one with the paperwork hassel attached.
Good advice about carrying only a copy of your current paperwork, and keep the original in a safe place. No need to have a LEO develope an attitude with you over nothing.
If you plan to only shoot it in semi-auto mode, if I were you I would'nt sweat shooting it. Almost no one would not know it is not an M1A, unless of course you activated the full auto mode. I doubt if anyone on the range would even give you a second look. If your range has a problem with you shooting semi-auto, you need to find another range.
