“We’re currently working with the ATF to make sure the gun doesn’t fall afoul of the laws against producing a ‘destructive device.'” Isn’t that always the way? You build something that does what it’s supposed to do better than anyone else and the world (i.e. the government) puts a barrier to the path to your door. I mean, what’s a shotgun for, exactly? If you can design a weapon that overcomes the main inherent disadvantage of a fully legal and time tested weapon with, say, a helical feed device on top and a spent shell catcher beneath, why not?
