Nuprol 4.0 Black Gas

This item will not be shipped overseas!

The Nuprol 4.0 Black Gas is one of the better gases currently available and therefore also the most popular green gas.

The reason why this is one of the better gases is because Nuprol's gas keeps a relatively constant FPS compared to other brands. This gas is also equipped with silicone to keep all the internal rubbers lubricated and to prevent them from drying out when you are not using your mags for a while.

Please note that this gas is not suitable for replicas with a plastic slide such as the Tokyo Marui Hi-Capa.

We always recommend to leave some gas in the magazine when it is not used for a while, to prevent the rubbers from drying out.
