I'm curious though as to why you link to a hopelessly outdated sticky regarding importations.
It would be one thing if there was a section that said, "Pistols? Muzzle energy too low. Fuggedaboutit." but it's just the old "Nothing can be imported, ever." mantra.
Even better, it's actually a threat of a ban for talking about it, then
the old "all airsoft are replicas" misinformation.
