Prometheus Metal Piston Head

The Prometheus Metal Piston Head is of very high quality and suitable for airsoft replicas fitted with gearbox versions 2 and 3.

This Piston Head is made of metal which makes it very durable but has the disadvantage of being a fairly heavyweight compared to the aluminium and polymer Piston Heads. All mounting materials are provided so you can mount it on your piston in no time.
This Piston Head is also equipped with bearings to prevent the spring from twisting.
