Well, I went up there today... and came back empty handed. Of all the lousy times to come up with a 'delay' on NICS... my first ever, no less. So it looks like I'll be going up there next weekend too!
First of all, though, they haven't got any of the Greek M1s yet, so I can't comment on them.
Second, so far as forms go--just take your documents (birth certificate, proof of firearms activity, club membership card). I went up there with an order form printed out from their website and was told that they didn't need them--they've got their own forms at the store, and the lady who works the counter is a notary.
Are you -sure- you can come from MD, though? I had thought (and I have only the very faintest grasp of federal/state firearms law; enough to know that most everything is regulated, though!) that there was some law about that. I meant to ask, but under the circumstances, I kinda forgot.
