HPA Pistol
HPA airsoft guns are powered by a small air tank that is connected to the gun through a hose. The air tank is filled with compressed air to a pressure of around 3000-4500 PSI, which is then regulated to a lower pressure by a regulator. The regulator controls the amount of air that is released from the tank, ensuring that each shot is consistent and accurate.
