I just talk to the Canadian customs and the girl told me that the person, the gun specialists, is actualy in jugdment of yes or no. So they didn't decide yet if they will ship it back to Fedex or seize it. Since it wasn't my first silencer, I didn't think there would be problem. I'll buy one from airsoftparts.ca if it's seized. And I'm curious to see the article of law they are suppose to send me for a fake silencer.
