Abstract
A harpoon-spear gun with pneumatic propulsion, which is mainly characterized by equaling the length of the barrel to the same approximate dimension of the whole rifle, said barrel being concentrically included in another tube greater in diameter, composing between both the existence of a coronary space, constitutive of the storage chamber of the air pressure, which is made specific to said space during the loading position and that expands until occupying the entire volume of the barrel at the moment of firing, to pass back to to compress itself in its primitive concentric space, when the air is forced back through the barrel, impelled by the piston-piston and by the harpoon itself during its load penetration.
