HPA ADAPTER VMP-2 (M4 MAGAZINES)

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.

Product Features:

• Compatible with VORSK VMP-2 platform
• Accepts standard M4 AEG magazines
• Modular plug-and-play HPA adapter design
• Injection-moulded polycarbonate adapter body
• Injection-moulded gas router system
• High-flow internal valve for efficient air delivery
• Printed feed lips for reliable BB feeding
• CNC valve collar reinforcement
• Standard US-style HPA fitting connection
• Adjustable rear shim for magazine fitment tuning
• Compatible with many M4 magazines (PTS EPM series recommended)
• Lightweight construction for improved handling
• Pressure-tested prior to shipping for reliability
• Typical field setups operate around 100-110 PSI depending on configuration
• Maximum recommended pressure: 150 PSI

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.

Range Overview:
