Its one-piece construction closely follows the profile of the original shotgun while providing a clean and durable HPA conversion.\u003cbr\u003e\u003cbr\u003eUnlike earlier designs, the latest high-volume adapter combines the upper gas section and M4 magwell into a single-piece body, increasing the available internal air volume. This allows reliable operation from approximately 80 PSI while maintaining consistent gas delivery throughout the firing cycle. The adapter is supplied fully assembled with an AIRTAC valve, injection moulded NBR gas router and gas router plate already installed, allowing installation straight from the box without transferring donor magazine components.\u003cbr\u003e\u003cbr\u003eManufactured from impact resistant polymer, the adapter is compatible with most Airsoft M4 AEG magazines. For optimum feeding performance, PTS EPM1 and EPM1S magazines are recommended by the manufacturer. An integrated BB retention system helps minimise ammunition loss during magazine changes, while the supplied US Foster fitting provides compatibility with standard Airsoft HPA airline systems.\u003cbr\u003e\u003cbr\u003eDesigned for use with regulated HPA systems, the adapter operates most effectively between 90 and 150 PSI, with a maximum recommended operating pressure of 150 PSI.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRange Overview:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAirTac’s HPA Adapters range converts traditional gas-powered replicas to use high-pressure air magazine systems with seamless reliability.
