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.

Platform UMAREX/VFC MP7 AEG gen1/gen2 TopMax

The piston head designed for the most demanding DSG and speed builds, helping achieve best results and overcome limits. Thanks to the use of 10 vents, airflow significantly increases improving sealing. The ultra-lightweight POM material together with CNC machining ensures repeatability of shots, perfect head-to-cylinder seal, high RPS ratio, and eliminates FPS drops. The adjustable AOE makes it essential for every speed build.

The BLACK piston head is CNC made in DELRIN on specific measurements by TopMax Elaborazioni. The incredibly low weight of 3.03 grams net and the DELRIN structure make this piston head reliable, durable and incredibly suitable for any type of configuration. The BLACK piston head is made with axial half-body vacuum holes

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 WHITE piston head is CNC made in DELRIN on specific measurements by TopMax Elaborazioni. The incredibly low weight of 3.27 grams net and the DELRIN structure make this piston head reliable, durable and incredibly suitable for any type of configuration.
