High-strength injection-moulded polymer body with integrated BB retention. Lifetime warranty included.\u003c\/div\u003e\n\n\u003cp\u003eEU-series GBB pistols use a distinct magwell format that isn't served by Hi-Capa or Glock adapters. The AirTac EU to M4 HPA Adapter is built specifically for this geometry, giving EU-platform players the same HPA conversion pathway that Hi-Capa and Glock users have: replace the gas magazine with the adapter, connect your HPA line, load an M4 magazine, and shoot with perfectly consistent air-fed performance.\u003c\/p\u003e\n\n\u003cp\u003eAirTac's high-strength injection-moulded polymer construction provides stable fitment and consistent alignment during active use. An integrated BB retention system prevents BBs from dropping out during magazine changes — a practical detail for fast-paced play where a fumbled magazine change shouldn't mean losing your loaded rounds from the adapter. US Foster HPA fitting is the industry standard and compatible with all mainstream HPA lines and regulators.

The EU-series platform's internals are designed around green gas pressure levels — 120psi replicates this closely. Always rack the slide before inserting the adapter. Use strong-spring M4 AEG magazines. Do not exceed 140psi.\u003c\/p\u003e\n\n\u003cdiv style=\"background:#1B3A6B;color:#fff;padding:12px 16px;border-radius:6px;margin:18px 0 0;font-size:13px;\"\u003e\n  \u003cstrong style=\"color:#fff;\"\u003e🔧 Titan Forge Airsoft tip:\u003c\/strong\u003e Not sure whether your pistol takes the EU, Hi-Capa, or Glock adapter format?
