The 90 m / s FPS spring has been calibrated on the original mechanics of the Well brand MB03 rifle.
Of course with shorter or longer rods the performance will decrease or increase, so it will go to the harder or softer calibration.
In the calibration process, the thickness due to the bearings was not taken into account, so that, given the same initial conditions, a performance increase of about 2.5 m / s must be taken into account for each bearing.

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