This POM piston head is a great upgrade that will increase the airflow efficiency through the cylinder.

6 ports on the front push out the o-ring as it moves forward, ensuring that all of the air in the cylinder is being pushed out to propel the BB.

The ball bearings help reduce rotational 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.

The lightest of the FPS piston heads, it improves the performance of your aeg, double o-ring and ball-bearing. This piston head is constructed out of CNC POM for durability and precision.

Designed and manufactured entirely Italy.
