Well the one thing that scared me is how it mentions that just possession of the replica firearm is illegal as well.
I'm just wondering . . . do we get a certificate or something that says it's okay to own? If so many of them have to be judged on a case by case basis, I don't want to take it to one con, have it deemed okay, and take it to another and have it taken away.
At least with a certificate, I can carry that in a belt pouch or something and whip it out and show them that it's cool.
Because I agree with the above . . . they do look real . . . like real star wars guns. If I saw someone walking towards me with one in a dark alley . . . they'd probably jump at least a step!
Fpoato . . you're at least probably okay with it shipping in kit form. It certainly won't look much like a gun in the shape it's coming to you in!
