Description.
The AirTac VMP-1 to M4 HPA Adapter is the go-to solution for players who want to ditch their gas magazines and tap into the benefits of high-pressure air — all while feeding from the most widely used magazine type in airsoft. Designed for the VORSK VMP-1, this adapter transforms your compact SMG into a consistent, high-capacity HPA platform without unnecessary complications or donor mag cannibalisation.
Inside, you'll find a fully integrated system that houses the gas router, feed lips, and high-flow valve assembly — all precision-moulded for tight tolerances and dependable operation. The CNC-reinforced valve collar adds an extra layer of strength, ensuring a leak-free fit even under heavy use. The design is plug-and-play — slide it into your VMP-1, hook it up to your HPA line via the standard US-thread fitting, and you’re good to go. It runs cleanly and efficiently around the 100 PSI mark, delivering stable shot-to-shot performance while supporting a much larger ammo pool than your typical GBB mag.
The real win here is compatibility. Whether you're running classic metal mid-caps or polymer PTS EPMs, the adapter handles a wide range of M4 AEG mags without issue. It’s compact, efficient, and dead simple to maintain — a great option for anyone looking to modernise their loadout and reduce downtime between reloads or refills.
Other Great Features are,
Lightweight polymer housing for agility and strength
Greatly increased magazine capacity over gas mags
Reliable cycling from standard field pressures
Clean install with zero irreversible modifications
