FPS SOFT AIR ergal bearing piston head with double o-ring lightened for high speed

Ball-bearing piston head in Ergal with double O-ring, lightened for high speed (XPAVN).
The new generation of FPS piston heads has been equipped with the new X-RING technology, and a one-millimeter plastic shim has been added to ensure the ideal engagement angle in every situation.
This head is specifically designed for fast bursts, both for its very low weight and its extremely low resistance to air recirculation within the cylinder.
In practice, this head is designed not only to maximize air compression during advancement but also to facilitate its restoration when the piston retracts.
All of this prevents power loss due to insufficient air pressure during the fastest bursts.
