Replicating the profile of a standard MK23 magazine, the adapter provides a compact and ergonomic alternative to larger magazine conversions while maintaining high internal air volume for reliable HPA performance.\u003cbr\u003e\u003cbr\u003eSupplied fully assembled, the adapter includes the valve, feed lips and gas router already installed, eliminating the need to transfer components from an existing gas magazine. The CNC aluminium baseplate provides a durable foundation, while the ambidextrous rear shell catch allows fast and intuitive shell changes during gameplay.\u003cbr\u003e\u003cbr\u003eTo maximise compatibility, the adapter incorporates two integrated grub screws that allow the distance between the adapter and nozzle to be adjusted, helping optimise the air seal and improve FPS consistency. Three interchangeable feed tubes are also included to compensate for manufacturing tolerances between different Airsoft shotgun shell brands, ensuring reliable feeding across compatible shells.\u003cbr\u003e\u003cbr\u003eThe integrated BB retention system feeds all 30 rounds from each shell without dropping BBs when the shell is empty. Supplied with a standard US Foster HPA fitting, the adapter is designed for regulated HPA systems operating between 90 and 150 PSI, with a maximum 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.
