The SpeedQB x Amped Line was developed to combine reliable function and style for the HPA airsoft platform. The original Amped Line was introduced during the rise in popularity of High Pressure Air (HPA) Airsoft systems in the United States and has since then become the Industry Standard.

The SpeedQB x Amped Grip Line (AGL) is an upgraded large bore grip line that attaches to the existing 6mm macro line in the pistol grip. The AGL uses a 6mm slip fitting that allows for a quick and easy installation process. It is also enclosed in durable nylon sheathing that maintains its flexibility while protecting it from damage during gameplay.
