I am posting this because it happened to me.
I meet a fellow on Facebook and sold him a CZ plastic gun stock.
This is part of the paperwork I got from Homeland.
This law has been on the books for over 100 years.
After I got my stock back two ICE agents came to my home.
They question me how I knew this fellow and given the third degree.
I got to be friends with a Homeland/ICE Agent from Chicago.
I know about his Russian wife and he likes to bake French pastries.
This ordeal took around 6 months to get my stock back.
If you want to ship anything firearm related you must have a permit
from the US State Department. That means screws, scopes, or anything.
The ICE agents were shocked that I had my stock back.
It must have cost US taxpayers $5000 over a $50 plastic stock.
I lost $65 from the Post office, $50 fine and $22 shipping back home.
