Action Army VSR10 M130 spring
Action Army Company's tuning springs are specially designed for the Tokyo Marui VSR-10 shooting system. The spring is made of high quality spring steel. Action Army specifically chose the linear design (equal coil spacing) for this spring because the spring has the maximum potential with this design.
This design ensures a power output of around 130 M/S (approx. 1.7 joules) with a perfectly sealed system.
The spring is only compatible with the Tokyo Marui VSR-10 shooting system.
