The Fusion and Super X2’s piston
has an “Active Valve system” regulating valve inside it. This regulating valve works independently of the piston, which make it more efficient than other gas operated systems and means that it lasts longer.
The “Active Valve system’s” Reliability & Versatility
> With light loads, the piston uses most of the energy generated by the gases for perfect operation.
With heavy loads, the excess gas is rejected through the piston’s side ventilation holes.
> Operates perfectly with all cartridges
from 28 g to 56g.
> The regulating valve has 3 segments which ensure that it is perfectly tight and that
the magazine tube is clean for excellent operation.
> The piston’s extremely short stroke limits the quantity of gas given off by the device.
