About Our Airsoft Electric Springs
The spring is the absolute core of how your AEG works, and is the first thing a lot of people go to when looking to change their output FPS. If you're looking to downgrade your gun (reduce how hard it shoots) then this is a good way to go.
A higher spring will put more strain on the components inside your gearbox, so we would recommend attempting to boost FPS through improving air-seal and other components such as your HOP Units/Rubbers, to increase output power without adding more stress internally.
Our AEG spring range is crafted using strong, durable components, helping you to supercharge your shot.
