Fitment
The fastest way to get an M4 magwell in front of your hand! This kit is comprised of an M4 magwell that fits onto your picatinny / pistol torch rail and feeds into your replica via a 'bowden spring' and shotshell or our modular HPA adapter base.
Shotshell
If you already have one of our shotshell adapters, simply install the kit onto your picatinny rail and insert the connected shell into your adapter!
Modular Base
If you already have one of our modular adapters (such as VMP1, MP7 etc), simply install the kit onto your picatinny / sight rail, unscrew the adapters current magwell (e.g. M4, MP5) and screw our modular adapter in.
Capa / Glk Adapter
For ultimate ease and a super low price, we created dedicated capa/glk bases that attach to your gas mag. This is all you need to HPA your replica. Simply install the kit onto your picatinny rail and install the adapter section like a regular HPA adapter.
Disclaimer
While healthy strong feed magazines such as the PTS EPM should feed entirely, you may need to slightly pull the bowden spring to feed the last few BBs. Especially when short stroked. The bowden springs 'tension' then causes the last few rounds to feed.
Cutting down your spring
As long as you leave an appropriate radius for BBs to flow, you can cut down your springs length to match your build. We provide a 250mm spring as standard.
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)
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
- Please note only 2 screws are required to attach the modular magwell, some adapters may have more
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.
