The AIRTAC EU Series to Shotshell HPA Adapter is designed to convert compatible EU Series gas magazine platforms to operate from an external High Pressure Air system while feeding from compact 30-round Airsoft shotgun shells. The low-profile design provides a lightweight alternative to larger magazine adapters while maintaining a realistic magazine footprint.

Supplied fully assembled, the adapter includes the valve, feed lips and gas router already installed, allowing it to be used without transferring components from an existing gas magazine. A 15 cm airline and blackened US Foster quick disconnect fitting are pre-installed for connection to a compatible HPA system.

To maximise compatibility, the adapter includes three interchangeable magazine catch shims that allow the magazine position to be adjusted for improved air seal and cycling. Three feed tubes of differing lengths are also supplied, enabling users to optimise feeding to suit manufacturing tolerances between individual shotgun shells.

An integrated BB retention system feeds all 30 rounds from each shell while preventing BB loss during reloads. The adapter is designed for operation between 90 and 150 PSI, with a maximum operating pressure of 150 PSI.
