Abstract
A pre-charged pneumatic airgun includes a reservoir, a stopper, a barrel and a manually actuated degassing tool. The reservoir contains a volume of compressed fluid and includes a discharge port disposed therein through which the compressed fluid is selectively discharged from the reservoir. The stopper is disposed in the discharge port and is moveable between a normal position sealing the discharge port in an actuated position allowing passage of the compressed air through the discharge port. The stopper is biased to the normal position by a biasing force. The barrel is in fluid communication with the discharge port. When the stopper is disposed in the discharged position, the compressed fluid discharged through the discharge port is further exhausted through the barrel. The manually actuated degassing tool is disposed in the air gun for manually overcoming the biasing force to move the stopper from a normal position to the actuated position, and for maintaining the stopper in the actuated position to degas the reservoir.
