The Bureau of Alcohol Tobacco Firearms and Explosives (ATF) went on a ban spree a while back because, according to them and nobody else, certain Airsoft rifles could be converted into real firearms. The ATF wrote up a report on this which coincided with their report on various unicorn sightings that their agents have observed over the years.
Well the ATF is going to shit bricks when they see this video explaining how to convert a regular staple gun into a 12 gauge shotgun. I’m kind of sad honestly, I use my stable gun a lot and there will be a void in my life when the ATF bans it for being easily converted into a destructive device.
