Prometheus - MS100 Non-Linear Spring
This Maple Leaf M100 spring is a non-linear spring suitable for AEG airsoft replicas. The non-linear structure of the spring means that this spring consists of several coil windings.
The coil windings that are closer together ensure that a lower resistance is reated than with the windings that are further apart. The advantage of this is that the teeth of the piston, which is located inside the gearbox, are significantly less stressed.
