What is HPA Airsoft?

HPA stands for high-pressure Airguns. This is a system that requires high pressure of air for improved fire rate and powerful blowback effect. HPA airsoft can be used for both AEG’s and GBB’s. They can be used on almost every weapon like guns, snippers, pistols, etc.

How do HPA works?

HPA is a system in which a tank is connected to the gun. When you pull the trigger, it utilizes air as a source of energy. Even if you start using HPA airsoft, batteries are compulsory. A pneumatic system is followed by HPA airsoft guns. Instead of an internal high-pressure canister, an external tank is used for high air pressure.

Difference Between HPA and AEG

In AEG, air pressure is used, but this air pressure is created inside the gun through using the power of batteries. HPA follows the same mechanism with the use of batteries but the tank is outside and is connected to the gun with a hose. Both AEG and HPA use the Pneumatic system.


If you have used Gas or an electric airsoft gun and now you switch to HPA, you will observe that when gas or electric gun is used alone, they might perform well but might not be as powerful as HPA airsoft gun. There is a mighty difference in efficiency and accuracy. Moreover, the power provided by HPA is ultra best.

High FPS

HPA airsoft has the highest FPS of all other guns. This is done by controlling the air pressure’s PSI. The higher the PSI, the higher the FPS will be. At long ranges, your shots will be more accurate as it has higher FPS.

Adjustable FPS

Every battlefield approves specific FPS. In this case, if your battlefield needs your FPS to be specifically low, then you can easily adjust it with HPA airsoft. Just lower the PSI through the air tank, and you are all set to go.

Is it Expensive or Not?

When you switch to HPA airsoft gun from an electric or gas system, then the whole new setup may feel a little expensive. But once you set it up and it’s time to refill the tank, then you will realize that it is cheap. You can take more shots from around 500-1000 with HPA. You may also need to charge batteries, but charges are less as the voltage is low.

Set-up Requirements

To set up an HPA gun, you will need some of the items. These items include an HPA engine, Air tank, Regulator and line, batteries, lubricants, and tournament locks. It is easy to find these items in a market, and you can connect all of them by yourself easily.

Carrying HPA Tank

HPA tank weighs less than 3 pounds but carrying it for a whole day on your back might be uncomfortable for some people. You have to put the tank in a bag, but then no space will be left for other accessories. It is better if you attach it to the chest rig.
