The AIRTAC Hi-Capa to Shotshell HPA Adapter is designed to convert compatible Hi-Capa and SSP5 gas magazine platforms to operate from an external High Pressure Air system while feeding from compact 30-round Airsoft shotgun shells. Its low-profile design maintains a compact pistol magazine footprint, making it suitable for users who prefer realistic magazine capacity and reduced bulk.

The adapter is supplied fully assembled with an injection moulded gas router, high flow valve and printed feed lips already installed, removing the need to transfer components from a donor gas magazine. A 15 cm airline and blackened US Foster quick disconnect fitting are pre-fitted, allowing connection to compatible HPA systems straight out of the box.

To improve compatibility, the adapter features an adjustable magazine catch system with three interchangeable shims that allow the magazine position to be fine-tuned for improved cycling and air seal. Three feed tubes of different lengths are also included, enabling users to optimise feeding performance 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 to operate between 90 and 150 PSI, with a maximum operating pressure of 150 PSI.
