would showing I have had a UKARA in the past, along with bookings... hell even photo evidence of me taking part in skermishes in the past. It's a shame I can't get the site owner to write a statement or something, given that the site no longer exists and I think Covid got him.
I'd rather not fly with the guns, explaining to security "Yes this is an airsoft desert eagle... yes it is all metal and yes that is also my shorty gas shotgun." Doesn't sound very entertaining. Of course, the other option is going through a shipping container with the rest of my stuff, at that point, I would have to tell the carrier what it is, probably have them packed up seperately in a gun case with the documentation of "They're not real officer, I swear" to which, that isn't a certainty either.
