High range bolt action pistol. This gun is very simple to make shoots very far. With a sharpened stick, it can go straight through a piece if cardboard. The design is all mine except the handle which I borrowed of the Auto Loading Assault Pistol. Has a very simple block trigger mechanism. It has a 6 round hopper secured by rubber bands that also close the roof so the blue rods can't fall out.
