So, if someone built an AR pistol with an un-serialized lower (“ghost gun”) an affirmative defense when the new law goes into effect would be “I removed the serial number???”
I don’t think that would be a good defense, would probably start with ghost gun. As it could be problematic to sit there and say " I decided to remove the serial number off of my gun". Also you have to clear off a decent amount of the guns material to remove the serial number, as technology in metallurgy and acid washes "could " bring the serial numbers back out.
You could say you built from the ground up with an 80% lower and be done with it
Hmmm. Just stamp the serial number from the removed lower and stamp it on the new lower.
It was a tongue in cheek comment.
If you were building a Ghost weapon,then why would you want a serial on it in the first place?
Isn’t that what the Ghost Busters used?
