Haw San Shell Head | Airsoft

Bought a Haw San Airsoft Shotgun. You can take the inner barrels out. I was thinking about printing an adapter to use Goblin Shells with it but thought this would be a good way to test first.

Results were bad ^^ , works better with inner barrels. But well perhaps somebody else wants to try around a bit to. These head fits good on my Haw San regular gas chambers - do a testprint and see if you have to adjust sizes since every printer has different tolerances !
