WE CT25 Shotgun Shell HPA Adapter
Choose options
This quirky little adapter acts as an extended grip and lets you run 30 round CYMA shot-shells in your WE CT25.
To install this adapter, you'll need a WE CT25 gas magazine.
Fit the included O ring to the base of the HPA adapter. Remove the baseplate of the gas mag, then use a hand clamp to compress the adapter onto the magazine shell, lining up and inserting the pins (fit the included O-ring ).
We include a 3mm dowel pin to allow leverage on the adapter when clamping.
Naturally FPS will still be as low as on green/red gas due to the very short barrel.
Drop the line on the opposite side to your hand on the grip and it can be held really nicely.
You will also be provided three feed tubes of different lengths. Sometimes, due to manufacturing tolerances of the shells, you may need to swap out the feed tube already pre-fitted to give the best feeding results. This video demonstrates how simple this is:
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
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)

Shotshell HPA Adapter Information
- Sites that do not usually allow HPA adapters in pistols should have no problem with these adapters, due to their low capacity, and covert profile.
- Compatible with most airsoft shotshells. We recommend CYMA or Golden Eagle shells, as they have the strongest springs (TM Shells are not as good). CYMA Shells Available Here
- 0 BBs are dropped when shell is empty (adapter will feed all 30 rounds of shell)
- An ambidextrous magazine catch is present at the rear of the adapter allowing easy shell drops
- Three feed tubes of different lengths are included. Sometimes, due to manufacturing tolerances of the shells, you may need to swap out the feed tube already pre-fitted to give the best feeding results. This video demonstrates how simple this is
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.
