Fully licensed FN SCAR AEGs made by Ares Airsoft is reviewed by Evike Matt in this video. The AEGs come with high quality CNC-machined 6063 aluminum upper receiver and polymer lower receiver, just like the real rifle. As expected from an Ares Airsoft-built AEG, they feature the unique ARES Electronic Fire Control System (EFCS - Safe / Semi / 3rd Burst / Full Auto) Gearbox, programmable via the EFCS control box (sold separately). The gearbox is also an advanced, reinforced design with a quick change spring system.
