You'd also need to be careful with that thing. First of all, the blaster from StarWars is based off of a real working MachineGun, actually the British Sterling submachine gun.
In the UK and in Canada such items are deemed to be replicas and would need special import restrictions, as they resemble real working firearms.
It sounds completely ridiculous, but I know collector who have had their "Replicas" or non functioning props in Canada seized by RCMP. They faced fines and jail time unless they took the case to court.
If you happen to live in the US, where those weapons laws happen to be commonsense laws then count yourself lucky.
