The kit consists of a spring guide in Ergal 7075 aeronautical aluminum alloy with triple fixing O-ring, the piston body in Delrin, a high performance self-lubricating material, guarantees optimal smoothness in the cylinder without wearing any components. The front part of the piston is equipped with an air seal Quadring that guarantees top-level performance.

The kit is equipped with a double unscrewable Airbrake with relative OR for an even higher noise reduction function.

Finally, the black burnished steel tail which guarantees a very high duration over time, while the burnishing allows self-lubrication to the mechanical parts.

Ps. the choice of inserting the O-Rings on the Airbrakes could decrease the output power also depending on the setup used.
