This airsoft gun comes with a quick change spring system allowing you to quickly upgrade or downgrade the FPS (Feet per second) rating of the gun with ease. This AMOEBA style rifle is part of ARES's new EFCS gearbox system (Electronic Firing Control System), which allows the gearbox to be programmed to be Semi, 3 round burst or full auto using the Ares Amoeba Electronic Gearbox Programmer EFCS. The new EFCS gearbox system means the AEG rifle comes with an electronic trigger, meaning an even quicker trigger response.
