The 120 m/s FPS spring was calibrated to the original mechanics of the MB01 rifle of the Well brand
Naturally, with shorter or longer barrels, performance will either decrease or increase, so it will be switched to the harder or softer calibration
In the calibration process, the thickness due to the bearings was not taken into account, so a performance increase of approx. 2.5 m/s per bearing should be taken into account under the same initial conditions
The FPS spring is 100% Made in Italy and has been manufactured in collaboration with leading companies in the sector
