Hi-Capa HPA/MP5 adapter

  • Sale
  • Regular price $80.00


This is a custom designed laser sintered nylon adapter that allows you to use HPA (high pressure air) and Echo1/Cyma MP5 AEG magazines on your Hi-Capa 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. This adapter installs to your gas magazine just like our M4 adapter. Please watch the installation video on YouTube titled: Primary Airsoft adapter installation tutorial HPA and M4 Glock + Hi-capa           https://youtu.be/AydmykdSGSM 

There are 2 versions of this adapter. One for WE tech / Armorer Works mags and one version for Tokyo Marui mags. You will need to install the adapter onto a 5.1 magazine which is the one with the long baseplate. The adapter will not fit onto a WE tech 4.3 magazine with the short baseplate. The adapter will fit into a 4.3 Hi-capa with a 5.1 magazine because the grip is the same on both 5.1 and 4.3 Hi-Capas.  The TM version adapter is the one with the long bb feed tube that prevents jamming from double stacking. 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 cross thread the fitting when installing a different one. The adapter does not come with a gun, magazine or any other accessories. The plastic spacer can be used to short stroke your slide if you choose to use it. 

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.
