The spring of an airsoft gun is a basic part that affects the gun's overall velocity (FPS・M/S) and ROF (cyclic rate). Additionally, LayLax's non-linear spring provides the same great performance boost of traditional regular springs in addition to reduced stress on your gearbox and motor as well as easier compression. Not only does the non-linear spring alter your velocity and cyclic rate, but it increases durability as well!
