HPA

HPA (High Pressure Air) is one of the propelling options for airsoft guns. It is a system that powers the gun with compressed air. It's not as widespread as the AEG/GBB, but you'll still run into it on the battlefield. HPA can give guns better shot repeatability, better trigger response, adjustable power, and low wear on the internal parts of the gun. However, it is the power that can be adjusted to high levels that is one of the reasons why some fields ban the use of HPA weapons. At the same time, you'll also be giving yourself a good slap on the pocket when buying a finished HPA gun or converting your existing gun to HPA. HPA guns are identified by the HPA tubing that leads into the compressed air bomb. You can also tell by the fact that everyone goes to argue with the owner of the HPA weapon after the game. But let's not forget that this is about people, not guns.

And what are the disadvantages of HPA? Besides the aforementioned high price, you also have to deal with that tube that sometimes gets tangled and degrades your maneuverability. Also, the air bomb weighs something, it's not fun to carry it around all day. You also have to refill the bomb, we refill HPA bombs by the way!
