Abstract From the Canadian patent
An arrow gun and method for propelling arrows or harpoons in which the gun includes a compressed gas source such as compressed air or CO2, 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 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.
