This isnt a particularly unreasonable example, I really can't understand why people are mocking it. It doesn't matter what the silencer is made from or if it works (at least half of the suppressors I have used have been totally useless), just that the person registering it claims it meets the requirements. Why would they lie?

This is basically a guy saying "hey I told the government service set up to record blue objects that something was blue and they believed me, tee-hee" when it the something in question was a potato, painted blue. It's just dumb.
