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.
For the most consistent reliability we recommend you use the Echo1/Cyma 110 round straight MP5 magazines. It also works with MP5 drum mags and curved MP5 mags but they look funny.
This is a custom designed laser sintered nylon adapter that allows you to use HPA (high pressure air) and MP5 AEG magazines on your airsoft pistol. To use it you will also need an MP5 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.
