FPS Airsoft Gearbox Variable Pitch AEG Spring

The FPS spring is 100% Made in Italy and was created in collaboration with leading companies in the sector.

The spring has coils with variable pitch in the central area and in the one in contact with the spring guide and undergoes a grinding process at both ends which guarantees optimal performance in the compression phase.

The material used is burnished and pre-hardened carbon steel wire with the addition of silicon and chromium EN10270 / 2.

The thickness due to the spring guide and piston head bearings was not taken into account in the calibration process.

For this reason, with the same initial conditions, an increase in performance of about 2.5 m / s for each bearing must be taken into account.

In the phase immediately following forming, the spring is stabilized in the oven at a temperature of 400 degrees centigrade for thirty minutes in order to optimize its duration over time.

The dimensions of the product are:

- length: 170 mm

- external diameter: 14.30 mm

It is recommended to use the spring in association with spring guides and bearing piston heads to ensure maximum performance and durability.
