■PROMETHEUS Non-Linear Spring
●Non-linear, irregular pitched designed to ease wear and tear on your gearbox
●Easier compression, with less overall stress ensuring greater durability
●Heat-treated for greater strength and consistent compression
■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!
■RATING: MS90 (90 m/s rating) matched for standard AEGs.
Please check that you are within the joule limits of your country before customizing your airsoft gun.
Be sure to abide by the Japan Sword and Gun law’s limit of 0.98 joules!
Check your airsoft gun’s performance in a large variety of settings, temperatures and other situations to be sure that the joule limit is not breached!
