I don't think they even looked at it tbh. Unlike MP Megatron there's not any metal in him to set them off. I can't imagine there'll be too much trouble getting these into the country. I would question the legality of them confiscating them anyway. He's hardly a replica pistol like MP Megs was.
I put my thoughts on the guy into the HEGEMON thread by the way.
I was worried about him getting snatched too, but I've had a bad habit of waiting too long on the 3rd party releases and either missing out or paying a premium later. Not many sites were carrying this guy so I wanted to make sure I didn't miss out.
He was worth the risk, IMHO.
