Irregular Pitch SP120 / S120+ Spring
A steel spring with irregular pitch intended for installation in any electric replica (also in spring-action replicas compatible with AEG springs) equipped with a Tokyo Marui standard gearbox.
Irregular pitch of the spring reduces its wear and reduces the effects of its compression as well as improves the replica’s reaction time to trigger squeeze.
