wasn't aware that that was illegal, but i don't care about attaching a bayonet to a rifle barrel. fixed blades are legal, anything short of full-auto fire is legal, and i find my knives to be more useful in my hand than on the end of my gun. it'd just get in the way of "normal" use; if Armageddon comes noone's gonna care if your gun has a knife attached to it, and if it's just on display it's legal as far as i know. and how often has that been an issue, anyway?
