That is pretty cool. I'd like to see it fired..........from a distance! It's also interesting in that it tends to dampen the ignorant argument that the "2A protects only firearms of that era". In the face of such a statement, I like to point out that the 2A referred to state of the art weapons which were identical to those used by the military.
So my Congreve rockets and French 12lbs's are good to go?
