This adapter allows you to use HPA and M4 AEG magazines with your Hicapa airsoft pistols. To utilize it, you will need an M4 AEG magazine, a paintball air tank with a low-pressure regulator (0-140 psi), and an HPA line with a Foster quick disconnect.
The standard operating pressure for green gas is around 120 psi, depending on temperature conditions. We recommend operating the pistol at pressures within this range and avoiding pressures exceeding 140 psi. It's important to note that higher pressures can potentially cause excessive wear and damage to the internal components of the airsoft pistol.
For optimal and consistent performance, we suggest selecting a high-quality M4 AEG magazine with strong springs. It is advisable not to keep the magazine fully loaded with BBs for extended periods, as this can lead to spring fatigue and a deterioration in performance. If the AEG magazine springs become worn, we recommend replacing them with superfeed springs.
