T1P Spare CNC GLK Shotgun Shell Baseplate (Color)
T1P Spare CNC GLK Shotgun Shell Baseplate (Color)
We’ve replicated a GTP9 gas magazine, and adapted it to take HPA, fed by 30 round shotgun shells.
- Easy access, yet low profile magazine release at the rear of the adapter.
- CNC Aluminium magazine baseplate with a choice of colours adding flair to your build!
- BB latch to prevent dropped BBs on reload (0 BBs are dropped when an empty shell is ejected).
- High internal volume for good FPS/PSI.
- Works best with CYMA Shotgun shells, available on the website.
- US Style Fitting as standard. EU Fitting available here
- This adapter requires a donor valve, gas router and feed lips from a LONG or SHORT gas mag
The adapter comes with a 15cm airline, which can be cut down to your preferred size, and a blackened Foster 22 (US Style) connector fitted.
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:
You will likely find that sites that do not usually allow HPA adapters in pistols, will have no problem with these adapters, due to their low capacity, and covert profile.
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)
Plug and Play
This adapter is ready to go out of the box. Valve, feed lips, and gas router are already fitted to the adapter. You do not need to use any donor parts.No assembly is required.

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.
