Choose options
A fully printed WE G36 magazine top with an M4 magwell prefitted! This adapter is fully plug and play, requiring no donor parts. We test every adapter in a WE G36 before shipping.
Features:
-
Compatible with most M4 magazines, works best with EPM and EPM1s
-
CNC Mag Release and Feed Tube
-
BB retention mechanism to reduce BB loss during magazine changes
-
US Style Fitting as standard
Our M4 base is injection moulded using a highly impact-resistant polycarbonate blend.
We recommend the use of a PTS brand magazine such as EPM-LR, EPM1RX, EPM-1, EPM1S. Many other brands of magazine will work. If a magazine does not fit, you can swap the rear shim at the back of the adapter.
DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT OUR EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT OUR EQUIPMENT TO A TIPPMAN STYLE HPA LINE

M4 Adapter Information
- Injection moulded from polycarbonate, this magwell is near indestructible!
- Compatible with most airsoft M4 magazines.
- We recommend EPM1/EPM1s magazines as they have excellent fitment and strong springs.
- Magazines advertised as Fast Feed such as the original EPM or Amarok magazines will also work well
- BB retention means only 2-3 BBs are dropped when changing mag
- A swappable rear shim is included
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.
