This adapter now comes with feed lips and a gas router fitted, making it fully plug and play.
This adapter allows you to run HPA on your Golden Eagle M4 (and the various guns that use their base design -- if your gas mags gas router looks similar to the images below, this is the adapter for you). Note the gas router is NOT FLAT but is angled upwards slightly towards the feed lips.
It is easy to confuse the Golden Eagle PMAG style magazines with GHK magazines. The main differentiator is that Golden Eagle M4 gas routers are angled upwards towards the feed lips.
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)
If purchasing an M4 magwell, your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.
*Drum mag not included with drum base. You can purchase drum here.

Key Information
- We use a US Foster Fitting as standard. This is the most common airsoft HPA fitting. EU fittings can be purchased separately.
- Some of our HPA adapters have a smaller internal volume than gas magazines. Because of this, you will need to use a PSI of 90–150.
-
If you need higher FPS, you can:
- Fit a tighter barrel
- Use a longer barrel
- Use heavier BBs
- Fit an improved hop bucking
- If your replica has an NPAS fitted, we advise opening it fully.
- Do not exceed 150 PSI. Many airsoft guns will not see an increase in FPS past this, as the hammer may struggle to depress the valve correctly.
- Insert the HPA adapter with your bolt / slide locked back to minimise pressure against the nozzle loading arm.
