This new Ares AM-008 is a brand new type of M4, created using ARES's new Electronic Fire Control System (EFCS) and based on their Amoeba range of airsoft weapons. The weapon has a polymer receiver, stock, and front RIS. The stock has four positions and houses the battery. This comes with a flip-up front iron sight and a removable rear sight. This rifle also works with the ARES / Amoeba Electronic Gearbox Programmer for ARES Electronic Firing Control System Gearbox so you can set your AEG to burst fire if you prefer. The trigger response is excellent and this rifle feels great to hold and has a great rate of fire! Please note as with all high quality AEGs this does not come with a battery or charger. If you require a battery or charger they can be found in our accessories section.
