A few years ago the ATF and others were all up in arms about 3D printed guns, I wonder how they are going to respond when they find out Paper Mâché guns are the new threat. The beauty of it all is the guns can be built around any cartridge. The downside is you have to wait for the glue to dry. At least one ATF agent is aware of the trend and he doesn’t have a problem with the paper guns. Special Agent I.B. Lyon said, “I kinda like them, it would be really easy to print a serial number on the guns.” People are already working on new ammo for these guns, the traditional spit wad method just doesn’t allow enough force to be exerted upon impact, it has more of a repulsive effect, especially if the projectile impacts somewhere in the facial region.
