When paired with the magazines above, this adapter will work with nearly all airsoft Hi-Capas.
AEG Magazine Compatibility
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.

AIRTAC Adapters
Each of our adapters is designed to be low profile while reaching field limit FPS. We design and manufacture all of our products to the highest standard, and do not charge extra for ‘premium’ features. Where applicable this adapter features:- Lifetime Warranty (Our adapters have to be built to last)
- 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.
- Seal Test
- Firing test, for feed and recoil (we have over 100 guns on site for testing)
Lubrication and Sealing
This HPA Adapter is made of polycarbonate. One of the most impact resistant plastics. When sealing your adapter use only 100% silicone oil. Silicone oil mixed with petrochemical solvents (often 'spray-on' type), or superglue / cyanoacrylate, will destroy the polycarbonate. Your adapter will last a lifetime if you use only silicone oil. If for any reason you need to attach something to your adapter, use an adhesive compatible with polycarbonate such as "Loctite Super Glue All Plastics"Compact MP5
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.
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.
