The F1 is a high performance, universal HPA (High Pressure Air) drop-in cylinder designed to fit virtually any AEG gearbox. It is available as both a Centerline version, which will work with most common gearbox types. It replaces the original gearbox components with a programmable pneumatic system allowing for higher performance, greater reliability and complete adjustment. We recommend that you consult or get assistance from an experienced Airsoft technician prior to attempting installation. Change your airsoft gun to an HPA build so you do not have to worry about maintenance necessary for electric airsoft guns.
