This adapter enables you to utilize High-Pressure Air (HPA) and M4 AEG magazines on your Hicapa airsoft pistols. To make use of it, you'll also require an M4 AEG magazine, a paintball air tank equipped with a low-pressure regulator (0-140 psi) and a HPA line with Foster quick disconnect. The standard operating pressure for green gas stands at approximately 120 psi depending on temperature conditions. We advise operating a pistol at pressures nearing this range and refraining from exceeding 140 psi. Keep in mind that higher pressures could potentially lead to excessive wear and damage within the airsoft pistol's internal components.
Our recommendation is to choose  a high quality M4 AEG magazine with strong springs for achieving optimal and consistent performance. It's advisable not to leave the magazine fully loaded with BBs for prolonged durations, as this might cause the spring to fatigue and result in performance deterioration. In cases of worn AEG magazine springs, we recommend replacing them with superfeed springs.
