MS120 Non-Linear spring

PROMETHEUS Nonlinear Spring MS120

●Non-linear irregular pitch to reduce wear on your gearbox
● Lighter compression with less overall stress, ensuring longer life
●Heat treated for greater strength and even compression

The spring of an airsoft gun is a fundamental part that affects the overall velocity (FPS M/S) and ROF (cyclic rate) of the gun. In addition, LayLax's non-linear spring offers the same large performance increase as traditional regular springs, in addition to less stress on your transmission and engine, and easier compression. The non-linear spring not only changes your speed and cycle rate, but also increases durability!
