Wanting to use a shotgun shell with your G5? We’ve reverse engineered & manufactured our own magazine, then put our awesome shotshell mechanism inside. Modelled on a 20 round PMAG.
A BB latch prevents dropped BBs (0 BBs dropped when shell is empty) and simple push mag release on the rear of the adapter makes it easy to change shells.
Supports full auto, and will absolutely rattle your fillings.
Features:
-
Lightweight magazine setup without an obvious HPA adapter aesthetic
-
Looks like a short smaller capacity M4 mag for DMR aesthetic
-
BB retention mechanism to reduce BB loss during magazine changes
-
US style fitting as standard
Requires only a donor GAS ROUTER from a GMAG. Does not require valve or feed lips, these are prefitted Please check our magazine section to see if the routers are in stock.
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:
Many customers buy this adapter by mistake, thinking it is for Golden Eagle M4s. Please ensure your magazines gas router is flat and not angled upwards towards the feedlips. If it angles upwards towards the feedlips, it is likely a Golden Eagle magazine / gun (see image below)
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.
