SHS AEG Tune-Up Spring Upgrade

The benefits of upgrading an SHS AEG tune-up spring include increased power and FPS, as stronger springs provide higher muzzle velocity. These springs are also durable and reliable due to their high-quality construction, often made from steel piano wire. Additionally, upgrades like the SHS M120 spring can be used in conjunction with other tune-up parts to boost the rate of fire while improving overall internal durability. 

Key benefits

• Increased FPS: A stronger spring will increase the velocity at which the BB is shot, measured in feet per second (FPS).

• Higher durability: SHS springs are made from high-quality steel piano wire and feature a variable pitch design, which can increase their lifespan and reliability compared to lower-quality alternatives.

• Performance boost: When combined with other SHS tune-up parts, like a high-speed motor, an upgraded spring can significantly boost the rate of fire and overall performance of the airsoft gun.

• Improved consistency: The variable pitch design of some SHS springs helps to mitigate tension points, leading to more consistent performance.

• Cost-effective upgrade: SHS springs are often praised for being a high-quality upgrade that is more affordable than many other brands on the market.
