This adapter comes with the "clone" gas magazine by Y P installed. It works with the Tokyo Marui MK23 as well as the SSX23 and clones. We recommend that you use high quality M4 AEG magazines with strong springs for the most consistent performance. Do not leave your magazines loaded with bbs for an extended period of time as this will cause the springs to fatigue and lose performance. Worn out AEG magazine springs should be replaced with superfeed springs. Our 4th generation Hi-Capa M4 adapter is injection molded from a strong glass reinforced nylon material. This adapter allows you to use HPA (high pressure air) and M4 AEG magazines on your airsoft pistol. To use it you will also need an M4 AEG magazine, “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 you 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. I designed this adapter to even the playing field when playing airsoft with a pistol as a primary against AEGs with hi-cap mags. 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 the threads when installing a different one. The adapter does not come with a gun, AEG magazine or any other accessories. Please be aware that some magwells may not be compatible with our angled adapter.
