Highlander goes of the Arcturus AK12 K "Begadi Upgrade Version" S-AEG in this video. The S-AEG designation means it is meant for the German airsoft market. This AEG is a result of the collaboration between Begadi and Arcturus, who aim to provide their customers with a strong and reliable S-AEG. The weapon comes with the Begadi CORE EFCS/MOSFET, the Mamba 19K Super High Torque motor with neodymium magnets, and a PRO HopUp already installed. It also has a VARIOHEAD with an adjustment tool, which gives the weapon maximum flexibility.
