Abstract: An arrow gun and method for propelling arrows or harpoons in which the gun includes a compressed gas source such as compressed air or CO.sub.2, a handle and trigger arrangement, and a high pressure air passageway system for linking the barrel to the gas source to propel or discharge the arrow. The arrow or harpoon is hollow and is slid over the barrel of the gun so that the barrel guides the arrow upon firing. The air passageway system is responsive to the actuation of the trigger such that the gun when loaded is not subject to pressure build-up and thus avoids accidental discharge hazards. Arrows with or without fletching may be used and are held in place when loaded without latching or locking. Arrows without fletching are held in the loaded position by a tapered seating gap arranged at the point where the barrel connects to the gun, while arrows with fletching are engaged in a shroud cover which surrounds the barrel at the gun handle end.
