  • Publication number: 20080078369
    Abstract: An airgun has a pneumatic mechanism that is driven by an electrical motor to provide a blast of air, wherein the pneumatic mechanism is in a non-coaxial and angled position relative to the barrel, and wherein the air is delivered to the barrel via a preferably angled intermediate conduit. Spatial separation of the pneumatic mechanism from the axis of the barrel allows for substantially simplified constructions and use of light-weight material, and further provides a wide variety of handgun designs as the only space requirement for the projectile delivery portion is the barrel. Therefore, in one especially preferred aspect of the inventive subject matter, the airgun is configured a revolver.
