ARES AM-009-BK Amoeba M4 Assault Rifle (Blue)

A quick change spring system allows you to easily upgrade or downgrade the FPS (Feet per second) rating of the gun. The AMOEBA style rifle is part of ARES’s new EFCS (Electronic Firing Control System), which is equipped with a semi-automatic, three-round burst, and full automatic gear box. The Ares Amoeba Electronic Gearbox Programmer EFCS comes with an electronic trigger, allowing a faster response to the trigger.
