Its adoption lightens the weight of the striking mass consisting of piston and piston head with a significant reduction in mechanical stress and noise.

The lightest among those produced by the FPS for shotguns with bursts up to 25/30 shots per second.

The BLUEPOWER 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 BLUEPOWER 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. Compared to the REDPOWER piston head, in the BLUEPOWER the size and position of the radial holes is further different to obtain greater aggressiveness in the compression phase of the O-RING while maintaining stability, constancy and precision in the shot.

The shape of the front part of the REDPOWER piston head has been studied to further reduce the stress due to the impact with the cylinder head PAD even at R.O.F. elevated. The REDPOWER head does not have the double sealing/centering O-RING, but has a small recess that decreases the contact surface with the inside of the cylinder, to reduce friction to a minimum. The total height of the TopMax piston head is standardized to the dimensions of the other piston heads on the market. The ERGAL and DELRIN insert for fixing the piston head on the piston is slightly shorter than the standard market size, in order to use the TopMax piston head on any piston on the market.

The innovative Delirio Head Piston in Ertalon+mos2 (polymer) made with the CNC machining, has been designed and calibrated to the thousandth. Its particular concave shape without the presence of the front anti vacuum holes, ensures high efficiency during the compression phase, guaranteeing a perfect concentration of the air flow so as to be pushed and routed directly into the nozzle of the cylinder head, avoiding the formation of air vortices

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
