Primary Airsoft TM Hi Capa HPA/X9 Adapter

This is a custom-designed laser-sintered nylon adapter that allows you to use HPA (high-pressure air) and X-9 AEG magazines with upgraded springs on your Hi-Capa airsoft pistol. To use it you will also need an X9 AEG magazine with an upgraded spring, a “paintball” tank with low-pressure regulator (0-140) psi, a hose with a Foster (polarstar) quick disconnect, and of course bbs. The normal operating pressure for green gas is roughly 120 psi depending on the temperature. We recommend that you run your pistol near this pressure and do not exceed 140 psi. Keep in mind that higher pressures can cause excessive wear and damage to the internal components of your airsoft pistol.

The metal quick disconnect fitting in the photos will come installed. The fitting is a US standard Foster Pneumatics 1/8 NPT quick disconnect. The fitting can be changed to any fitting that has 1/8 NPT threads. Be sure not to damage threads when installing a different fitting. The adapter does not come with a gun, magazine, or any other accessories. The included plastic spacer can be used to short-stroke your slide if you want to use it.
