The sleekest way to HPA your VFC M4.
We've designed this HPA adapter to sit completely inside the magwell with an elegant two part magazine catch, and an adjustable side shim system for stability across all metal CYMA MP5 mid caps.
Works excellently with the T1P HPA Dead Drop Grip.
Comes pre-fitted with valve, feed lips and gas router - you do not need to use any donor parts. No assembly is required.
SHIM ADJUSTMENT INSTRUCTIONS
If a CYMA MP5 magazine seems two wide, remove one of the two side wings, marked red on the image below, using a 1.5mm hex key. Some gentle filing of the shims can also be done to improve fitment in the case of CYMA MP5 mags that are stamped too wide.
If a straight MP5 magazine is not feeding or has too much vertical play, install the fitment block inside the magwell, shown in the image below
Product Information
We test each adapter in a VFC M4 before shipping.
The gas router for this adapter is made from injection moulded rubber, to the standard VFC spec and dimensions, meaning you can use a factory or aftermarket VFC M4 router should you wish.
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 rear shim is included, which can be fitted to increase air seal (due to manufacturing tolerances between various brands of receiver).
A BB stopper is fitted to prevent too many BBs dropping when removing the magazine
Includes rear shim, one set of spare feed lips, one set of side shims and all screws required to fit any of our modular magwell bases.
US Style HPA Fitting as Standard (most common fitting across industry - compatible with all AIRTAC HPA equipment)
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

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.
