This is a very powerful crossbow which I created. It is fairly lightweight, has a range of 40+ feet, has a stock, and a sight.
THE MOD OF THE C3, THE C3.1 IS NOW UP: http://www.instructables.com/id/The-Lego-C31-Shotgun-Crossbow/
. IT IS A SHOTGUN-CROSSBOW, THE FIRST OF ITS KIND BECAUSE IT FIRES A SHELL WHICH RELEASES MULTIPLE PIECES IN ONE SHOT.
