A selection of springs to be used inside the AEG gearbox, the power output cannot be guaranteed as is dependant on other factors within the gearbox, barrel and hop chamber but below are rough estimates of what they are supposed to give:
M90 Spring - 300-330fps
M100 Spring - 330-350fps
M110 Spring - 350-380fps
M120 Spring - 390-420fps
M130 Spring - 420-450fps
M140 Spring - 450-490fps
M150 Spring - 490-540fps
*Actual power will vary from gun to gun and the above fps should be used as a guide.
