HPA ADVANTAGES FOR GBB

The proper functioning of gas guns is highly dependent on the ambient temperature. Especially in sub-zero temperatures it is practically unrealistic to use a gas gun. The gas pressure decreases as the ambient temperature drops and the gas in the magazine is in a liquid state. It gradually evaporates during firing, which further cools the entire system.

But all that changes with the HPA. Compressed air is still in the gaseous state and therefore there is virtually no cooling during firing. In addition, its pressure is not as dependent on the ambient temperature as it is with gas. Simply connect your HPA system to the gun using the EPeS HPA adapter and you can let the slides ring out even on ice or snow.
