SHS M150 AEG Upgrade Spring (TH1017)

The SHS M150 Dual Stage AEG Upgrade Spring is a high-performance aftermarket spring designed for Automatic Electric Guns.

This powerful spring incorporates a dual stage coil design, where the coils vary in spacing to apply different levels of force at various points in the stroke.

This contrasts with standard constant rate springs and enhances your AEG’s shooting power and consistency.

This is a M150 spring made by SHS. This is a dual stage spring, which means the coils get farther and close together in different parts of the spring. This is the way all aftermarket springs are while stock springs are constant rate.

It changes how much force the spring applies at different points in the stroke. This spring is very powerful and should only be installed by an seasoned airsmith who knows how to build a gun that can handle this spring.
