The Amoeba Series by ARES is focused on providing the most competitive field ready AEG available. The pre-upgraded internals feature an all new Electronic Fire Control MOSFET unit that allows this gun to be used with a LiPo battery without any further upgrades. This EFC unit increases rate of fire, trigger response, and shields the internals from over discharges of the battery. The fire rates are adjustable to incorporate a 3-round burst, single only, and all three combined (requires EFC Programmer). Externally, the gun features an impact-grade body that is made out of nylon-fiber polymer. The free-float rail system is made out of CNC machined aluminum that has a perfect finish and tight tolerances. Designed to be incredibly modular and ergonomic, the rail segments can be moved to position all tactical accessories right where the user desires. Below the rail system is the barrel and mock suppressor that are concealed for a low profile. The skeletal stock is quickly retractable/extendable to transition from CQB environments to field environments in a flash. Laser etched into the body is the ARES Amoeba Spartan logo and a unique serial number. This AEG is innovative and engineered to outperform its other airsoft gun competitors.
