Piston Head Prometheus Version 2

Improve the air seal and thrust of your Tokyo Marui NGRS V2 gearbox with this Prometheus Version 2 piston head.  

This piston head has been specially developed by Prometheus for Tokyo Marui NGRS airsoft replicas that contain a V2 gearbox. The POM (polyacetal) material used provides a strong, hard and dimensionally stable base with very low frictional resistance, which means that this part offers extremely low friction inside the cylinder. This also significantly improves the durability of the piston head.  

At the rear, this piston head contains a special thrust bearing that is surrounded by a POM housing. Thus, only the piston head can move. This counteracts the rotation of the spring and optimizes the force distribution.  

Please note: this piston head is only suitable for Tokyo Marui NGRS replicas that contain a V2 gearbox.
