What is HPA?

Put simply, high pressure air (HPA) airsoft guns use air to shoot out BBs in an airsoft gun. It's quite a unique system that takes components of gas blowback systems and Automatic Electric Guns (AEGs), making a completely different system that is electric pneumatic. This is an exploding area of airsoft known as HPA. How does it work? Let’s start with the action of pulling the trigger. Once its pulled, the Fire Control Unit (FCU) reads a shot and tells the engine to push out the air that's in your tank. When making the switch to HPA, you don't have to worry about AEG issues with maintenance. Instead of having a motor move the gears, pushing the spring back, building pressure in the cylinder and releasing it through the nozzle to force the BB out of the barrel, there's only one moving part in and HPA engine. That's the nozzle pushing the air out. In an HPA system, the entire flow of what happens after pulling the trigger is shortened by incredible lengths. You just need a tank with regulator, line and engine. With HPA you can shoot and have a near limitless supply depending on the tank how much air you have.

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
