If I recall correctly, the Americans have some laws about Deactivated guns, as in not allowed. I could be wrong on that, but it seems to me, that the Yankee government would prefer someone to own a non functioning replica than a dewat. Reason being that Dewats can be reactivated and the Boys and Girl at Red Jacket (Sons of Guns) have shown. That said, Bringing a Dewat into the States...... ask, the local Yankee cops, states Government officals, ect. cover your back side, ect. One wrong move and end up breaking a Firearms Law and you could have Bubba for a cell mate and Bubba doesn't have Vasiline!
I know we have some really stupid laws here in Canuckistan, but they have some even dumber ones south of the boarder. At least here in Canada the laws are consistant across the country. Down there, if you take a road trip, you have to plan out your trip because what may be legal in your State, County, Town, City, ect. may not be legal in the next one and just driving through can land you in the Crowbar Hotel!
