This adapter comes with a valve pre-fitted, making assembly trivially easy. Simply unscrew the two screws on top of your gas magazine, and move over the feed lips / gas router onto our adapter.

This adapter allows you to run HPA on your Golden Eagle M4 (and the various guns that use their base design -- if your gas mag looks similar to the image below, this is the adapter for you)

We utilise a very high flow valve. This has allowed us to build a far more reliable adapter that is capable of high FPS and sustained full auto.

A side shim system is included, which can be fitted to increase air seal (due to manufacturing tolerances between various brands of 'Golden Eagle/WA' receiver)

US Style HPA Fitting as Standard (most common fitting across industry - compatible with all AIRTAC HPA equipment)
