  • This adapter allows you to use HPA (high-pressure air) and M4 AEG magazines on your Poseidon pistol.
  • To use it you will also need an M4 AEG magazine, “paintball” tank with low pressure regulator (0-120 psi), a hose with a Foster quick disconnect.
  • 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 don't exceed 120 psi.
  • Keep in mind that higher pressures can cause excessive wear and damage to the internal components of your pistol.
  • We recommend that you use high-speed M4 AEG magazines for the most consistent performance.
