The AIRTAC VMP-2 to M4 HPA Adapter converts the VMP-2 platform to run high-pressure air while feeding from standard M4 AEG magazines. Designed as a compact evolution of the VMP-1 adapter, it integrates the gas router, valve system, and feed components into a modular plug-and-play unit that installs without requiring donor gas magazines.

The AIRTAC VMP-2 to M4 HPA Adapter provides a modular conversion system that allows the VMP-2 platform to operate using high-pressure air while feeding from widely available M4 AEG magazines. Designed as a shortened evolution of the original VMP-1 adapter, the unit is shaped to match the aesthetics and profile of the VMP-2 platform while maintaining reliable HPA performance.
The adapter features a fully integrated plug-and-play construction that combines an injection-moulded gas router, high-flow valve assembly, and printed feed lips into a single unit. This design removes the need to dismantle gas magazines or harvest internal components from donor magazines, simplifying installation and improving long-term reliability.
Constructed from a highly impact-resistant polycarbonate blend, the adapter maintains a lightweight profile while providing durability for regular field use. The internal high-flow valve system ensures efficient air delivery and consistent cycling across a wide pressure range, while the CNC-reinforced valve collar helps maintain a secure and stable seal.
The adapter connects to standard HPA systems using the supplied US-style fitting, the most common fitting standard across airsoft HPA equipment. Typical field setups operate around 100–110 PSI depending on platform configuration, though pressure should never exceed 150 PSI.
For installation, the paddle magazine latch on the VMP-2 must be removed to allow the M4 magwell adapter to sit flush against the receiver, while the side magazine release remains functional. This modification requires removing a single screw and can easily be reversed if required.
By combining modular construction, reliable airflow, and compatibility with widely available M4 AEG magazines, the AIRTAC VMP-2 HPA Adapter delivers increased magazine capacity, improved shot consistency, and simplified magazine management compared with traditional gas magazines.
