This handheld, firearm is a non-lethal weapon. It shoots a tiny case-less dart comprised of a powerful sedative. As the material is absorbed into the bloodstream it renders the target unconscious. The projectile is launched by a blast of compressed air. The gun's high pressure level is maintained by manually ratcheting the gold barrel crank to fill internal air cylinders. It's a close combat weapon with an effective range of 50 feet.
