"The ARES M4e is features a whole new level of electronic involvement in an AEG. The ARES M4e has an ECFU (Electronic Control Firing Unit) which allows the gun to be programmed by an external computer. This process allows the user to have the Semi and Full Auto selections modified to fire in a burst, from 1-10 bbs.

Additionally, the M4e features a MOSFET, which monitors battery usage and power into the gun, protecting the gearbox and internal components from excess stress. The MOSFET may also be programmed to stop firing if a battery's power gets too low for safe operation. Featuring rock solid, full metal construction and a commercial spec buffer tube for larger battery storage, the m4e is sure to impress those looking for a quality metal AEG.

HSA EXCLUSIVE: For the month of May, ALL ARES m4e AEG purcahses will include a FREE box of 10 ARES mid-capacity magazines!"
