AirTac HPA Adapter – EU-Series Pistol to M4 Magazine

Upgrade your EU-series gas blowback pistol with the AirTac HPA Adapter, allowing seamless use of standard M4 AEG magazines powered by high-pressure air. Designed for players who demand consistent performance, higher ammo capacity, and reliable operation in all weather conditions, this adapter delivers a major step up in efficiency, control, and reliability.

Precision injection-moulded from a high-strength polymer blend, the AirTac adapter offers an ideal balance of durability and lightweight handling. A pre-installed US-thread HPA fitting ensures fast connection to most HPA lines, while the integrated BB retention system prevents feed loss during reloads and magazine changes.

By switching to HPA, players gain stable FPS output without gas cooldown, maintaining reliable performance even in cold temperatures. The ability to use standard M4 AEG magazines significantly increases ammunition capacity, reduces reload frequency, and improves overall gameplay flow.

Supplied with a removable magwell insert, shim set, and mounting hardware, the AirTac adapter allows fine tuning for a secure, wobble-free fit across compatible EU-series pistols.
