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.
Canucks, If they are forcing you to surrender your firearms, it is because they have something planned for you that you are not going to like!
First comes the gun confiscation then comes the genocide. Think Stalin, Hitler and the killing fields to name a few.
What mass killings by Hitler? After all we've learned over the past 8+ years, do you believe what you've been told about WWII and before?
Do you disagree that Hitler implemented gun control measures and confiscation to disarm and repress his population including his political opponents?
I don't know anything about firearms laws during that era in Germany, but I don't trust written history now.
