WE HAVE UPDATED THE KNOCKER FOR THIS ADAPTER TO ONE THAT HAS A SPRING AND A MOVING PIECE. IF YOU DO NOT HAVE THIS, CONTACT US AND WE WILL SEND YOU ONE OUT! THIS WILL GIVE YOU FPS CONSISTENCY
We recommend the use of an NPAS with this adapter, in particular the Waldo Crimson VFC NPAS. This is vital for 1-1.3J range users
Allows the use of your VFC AK74 with AEG mags, powered by HPA. Recoil and full-auto are excellent when using this adapter.
The adapter comes pre-fitted with an outlet valve, gas router and feed lips. No assembly required.
Your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.
Includes a spare set of feed lips

We design and manufacture all of our products to the highest standard, and do not charge extra for ‘premium’ features.

- Injection moulded or CNC magwell that is impervious to BB strikes at point blank skirmish FPS.
- CNC or Injection moulded Feed Tubes and Magazine Catches for lifelong durability.
- Tuneability/compatability via integrated shim systems. Our adapters are designed to cope with 'airsoft tolerances'
- Gas Routers injection moulded from NBR, 1:1 with the factory gas router.

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.
Run different mags with your adapter!
