Responsible gun owners have a duty to keep guns out of the hands of criminals. If you are forced to surrender your guns against your will make sure they are useless. Just in case they get lost on their way to be destroyed. For safety.
A dab of JB weld in the chamber should do the trick. Once the bolt closes, it ain't ever shooting again.
EDIT: To all the folks saying "Muh 1776!"... Only a small percentage of Americans went to war with the redcoats. A lot of people comply, for many reasons. This is for them, retailers especially, they can at least guarantee these guns don't go to Ukraine, Syria, ISIS, Gangbangers, etc.
Interesting. It used to be the fact that freemen would be obliged to own weapons to secure a free state.
Where the people no longer secure a state, that state has become a slave state.
In regards to foreigners and immigrants, they have had to wait till the ninth generation before they would reach the level of full BURGHER position and the capacity to own land.
4th generation foreigners would have a choice to answer to call to arms and weapons would then be provided for that particular call.
In North Western Europe the way things were organized differed somewhat from confederation to confederation, yet followed analogous lines. Certain Germanic principalities were incapable of maintaining standing armies, and went so far as to fine any freeman encountered on the street unarmed.
