Piston Head Pressure Deviation [FPS SOFTAIR]

FPS CNC Aluminium Double O-Ring Ball Bearing AEG Piston Head Pressure Deviation.
The FPS piston head is a great upgrade that will increase the efficiency of airflow through the cylinder.
This piston head has ports on the front to push out the o-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.
The ball bearings help reduce tension created by the spring compressing and expanding, this combined with a ball bearing spring guide is the optimal set up to keep your spring in good shape.
Each FPS piston head is made of aluminium 7075-T651 and it is also anodized for smooth surface finish.
This is the most advanced version with 8 ventilation holes.
Designed to divert the pressure in the inner part of the oring increasing dilation, double o-ring and ball-bearing.
The piston head is constructed out of CNC for durability and precision.
This product is designed and manufactured entirely in Italy, by technicians who have years of experience in the repair and modification of airsoft replicas.
