HPA Adapter VMP-1 (M4 Magazines) AirTac

HPA ADAPTER VMP-1 (M4 MAGAZINES) AIRTAC

The AIRTAC VMP-1 to M4 HPA Adapter converts the VMP-1 gas platform into a high-pressure air powered system capable of feeding from standard M4 AEG magazines. Designed for simplicity and reliability, the adapter integrates AIRTAC’s modular plug-and-play architecture.

The adapter contains a fully integrated gas router, valve assembly, and feed system, removing the need for donor gas magazines or complex installation procedures. This construction allows the adapter to be installed quickly while maintaining reliable air sealing and consistent BB feeding.

The internal high-flow valve system delivers stable airflow to support consistent cycling, while the reinforced valve collar improves durability during prolonged use. Combined with the injection-moulded gas router and printed feed lips, the adapter ensures dependable feeding performance.

With compatibility across a wide range of M4 AEG magazines, the adapter provides significantly greater magazine capacity compared with traditional gas magazines. The standard HPA fitting allows connection to most airsoft HPA regulators and air systems.

The result is a compact and efficient HPA conversion solution that enhances shot consistency, magazine capacity, and operational reliability for the VMP-1 platform.
