Spring RCS Top Max

The central stabilization narrowing allows the spring to maintain a more linear and rectilinear position inside the air unit, minimizing lateral displacements and maximizing the life span of the spring, moreover the constant performance of the RCS spring allows to obtain a firmer shot.
