Abstract
An arrow gun is provided having a controllable retention force on the arrow. By setting the retention force on the arrow, increased energy from motive compressed gas can be imparted to the arrow. The arrow gun also includes a damping coupling for reducing vibration of an unsupported length of the barrel.
Claims17
An arrow gun using compressed gas to propel an arrow having a hollow portion, the arrow gun comprising:
- (a) a receiver;
- (b) an elongate barrel having a longitudinal axis, the barrel connected to the receiver at a fixed connection, the barrel having an outer diameter sized to be slidably received within the hollow portion of the arrow and terminating at a free end;
- (c) a damping coupling between the receiver and the barrel, the damping coupling longitudinally spaced along the barrel from the fixed connection to be intermediate the fixed connection and the free end of the barrel;
- and
- (d) wherein the barrel has an unsupported length of approximately 12 inches to 36 inches between the damping coupling and the free end.

An arrow gun using compressed gas to propel an arrow having a hollow portion, the arrow gun comprising:
- (a) a barrel sized to be received within the hollow portion of the arrow;
- (b) a gripping surface having a first configuration exerting a first retention force on the arrow receiving the barrel within the hollow portion and a second configuration exerting a different second retention force on the arrow receiving the barrel within the hollow portion;
- and
- (c) a collar moveable relative to the barrel to dispose the gripping surface between the first configuration and the second configuration.
