Prometheus Airsoft AEG Non-Liner Tune-Up Spring

The spring of an age 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!

Features:

• 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
