Metal Bearing-Mounted Piston Head
As the mythical Prometheus has delivered fire to humanity and taught us basic technology, so does Prometheus bring us modern technical solutions for our airsoft replicas.
The metal piston head by Prometheus was made from a uniform block of material and cut using precise CNC machines, which makes it very durable. Bearings of the head reduce the wear of the spring and prevent it from cracking during operation.
