Additionally, by law, the only person who can require you to show the paperwork is an ATF agent. It clearly states it in the law. 26 U.S.C. sec. 5841(e).
Whether you want to fight that battle in the field is up to you. I asked that question to our resident ATF agent (I work at a SOT gun shop) and she confirmed that and she said she informed local law enforcement (sheriff's offices) and the F&G of that requirement also.
Interesting, to say the least, considering the hassle to just get a stamp!
