flying with airsoft guns to Hong Kong and back to Toronto
 

Hi everyone so I'm planning to participate in an airsoft game in Hong Kong. I might bring my own gun for this purpose and also bringing it back to Canada(Toronto specifically).
Has anyone ever tried flying with airsoft guns to Hong Kong and back to Canada?
And when I'm bringing the gun back to Canada does the gun need to be within 367 and 499 FPS? Since it has to be within this range when buying a gun from evike.com I guess you can only bring guns within this fps range?
Thank you and have a nice day :)
