I've been reading into the subjective hailstorm that is "to get a C&R or not", there's something I'm a tad confused about. For NFA items, did I read correctly that if I found a C&R bren at a show I could show my licence and walk out with it? Or they'd ship it to me after payment? What about the finger cards/photo/paperwork/background check that takes forever?

I do apologize for asking this perennial question yet again, but as many C&R guns I've seen online require a C&R licence on the part of the buyer (that is, the seller's requirement is the buyer has one for the transfer), I feel compelled to seek clarification. I'll probably call ATF next week and ask there too. Have not seen this particular tack on this question answered to my satisfaction online.
