RESORT DE 90 M/S PENTRU MB03/VSR10

WELL MB03 90 m/s FPS spring has been calibrated on original sniper rifle.

Of course with shorter or longer barrel the performance will decrease or increase, therefore the calibration will be harder or softer.

In the calibration process has not been taken in consideration the thickness due to the bearings of the spring guide.

So, starting by equal initial conditions, you have to take into account of a performance increase of about 2.5 m/s for each bearing.

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