The Amped Integrated Grip Line or IGL is Amped Airsoft’s original solution for replacing the weak and flimsy macro line that typically powers HPA conversion for airsoft replicas. This IGL is an exclusive collaboration between AirTac Customs and Amped Airsoft, with "AirTac Customs" text and the AirTac logo on the black sheath. The IGL is constructed from a durable, wide-bore line and bears Amped's superior quality. As always, every piece is hand-made and tested right here in the good ol’ USA and carries our lifetime-limited warranty against manufacture defects.
