Description

FPS WELL MB03 / VSR  m100 SPRING

FPSWELL MB03 / VSR  100 m/s  spring has been calibrated on an original sniper rifle.

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

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

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