FPS Piston air brake piston head POM with double or piston angle adjustment (XPAA)

The SUNPOWER piston head is CNC made in DELRIN on specific measurements by TopMax Elaborazioni. The DELRIN structure makes this piston head reliable, long-lasting and incredibly suitable for any type of configuration. The SUNPOWER piston head is made with axial-internal anti-vacuum holes and radial outlet holes, which allow for better distribution of the air on the sealing O-RING, speeding up its expansion in the compression phase. The size and position of the radial holes is specifically designed to obtain an optimal compression phase of the O-RING while maintaining stability, constancy and precision in the pull.

Maxx Model, CNC aluminum piston head with double oring bearing to improve the performance of your electric ASGs

made of high strength agglomerated polymer, this head is designed to meet the needs of high gusts (up to 50bb / sec) without suffering deformations due to high temperatures.

The FPS ERGAL piston head is a great upgrade that will increase the efficiency of airflow through the cylinder, ensuring an air tightness never seen beforeThis piston head has ports on the front to push out the o-ring as it moves forwards, this ensures that all of the air

The lightest among those produced by the FPS for shotguns with bursts up to 25/30 shots per second.
Its adoption lightens the weight of the striking mass composed of piston and piston head with a significant reduction in mechanical stress and noise.
