I came up with this gun design a year or so ago. I think the idea for such a wide barrel has been done, like the bug-squarish one, "Special munitions" or something. Even this use of gray rods has been done as a grenade launcher- but never with a trigger. The usefulness would be to use as a shotgun, of course, or fire those little black circle things. I've taken this apart some time ago, but it could be rebuilt. I realize the wide ramrod tip would seriously decrease power, but it is a less piece-consuming version of the barrel seen on the previously mentioned "special munitions" (or something) gun. Does anyone think this is valuable?
