We are achieving 1J@100psi on a 0.25g BB. This means heavier BBs or higher PSI will put you way into or above UK field limits and closer to DMR (you can go up to 130PSI on this adapter). The adapter cycles well down to 80PSI.
CNC Valve Collar (This means no valve on plastic thread, for a FAR more durable adapter)
-
US HPA FITTING as standard, EU push fitting can be found on the website
- Rack your gun before insertion of the adapter
It doesn’t end there, we offer excellent product support, lifetime warranty, and provide free spare parts should you or your team ever need them!
Installation
A donor mag is required to build this adapter. You will need to remove the gas valve, feed lips, gas router and valve knocker from your gas magazine, and install them onto our adapter.
We pressure test each adapter before shipping, to ensure that your valve will drop straight in and seal! We require donor parts to ensure absolute compatibility with your RIF.
Configurations
Modular Adapter Top
This is the 'top' part of the modular HPA adapter, and is available for purchase so you can use your existing modular bases, saving you money!
M4
Compatible with most M4 magazines, works best with PTS EPM1. Your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.
MP5
Compatible with all CYMA MP5 Mid Cap Magazines
Shotgun Shell
Compatible with CYMA Shotgun Shells and some other brands
Drum Base
Allows your HPA adapter to be used with a Tokyo Marui MP5 or VZ61 drum (or a Well/Jing Gong one if you can find them). The drum itself can be purchased separately here
Modular Mag-wells also Sold Separately!
Modular Mag-wells can be purchased individually here. I recommend mixing one high capacity mag-well, e.g. M4 or MP5 with a limited capacity mag-well such as the shotgun shell base, for those sites who don't like HPA adapters, or for when you want a more 'realistic' setup, while still running HPA.
PLUG AND PLAY - We've injection moulded our own gas router for this adapter, and combined it with our high flow valve and printed feed lips. This means no more donor mags!
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.
Run different mags with your adapter!
