Another AEG that you might consider to be vintage but still in production is the Tokyo Marui MP5SD5 AEG and is featured in this video by Classic Airsoft. The Tokyo Marui MP5SD5 AEG features a Version 2 Gearbox, a powerful EG700 motor, a fixed stock that can accommodate a large battery, and a sturdy silencer. This SMG is the longest in the MP5 series. It is mainly used for CQB by airsoft gun players.
