ABSTRACT:
A compressed air gun comprises a plastic casing, in which a low-pressure cylinder is arranged beneath the gun barrel and a high-pressure cylinder is arranged behind the barrel, with a pressure release system between the cylinders. Two pistons are contained within the respective cylinders and are connected to a cocking lever each by a separate hinge rod. A series of catches and releases requires all operative steps to be completed in the correct sequence before firing to prevent overloading of the air pressure system and also to prevent accidents.
