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.
Thanks for that. I'll add a few things to your good points.
One doesn't have anything to do with the other. As we know, nearly all of the "mass shootings" are planned for political reasons. The more shootings that are planned, the more that the normies think they want guns eliminated. If they would use even one brain cell and figure out who actually wants guns eliminated (hint - it starts with govern and ends with ment) they might understand how the mass shootings help their agenda.
Remember - without guns we will become worse than Australia. There will be no more checks on the government's power.
Everyone needs to brush up on their Charlton Heston:
Yep. THAT'S the general idea...
So far they've been smart enough to keep their distance.
