Mach Sakai reviews one of the early Micro-AEGs from Tokyo Marui and also a favourite for CQB games before, the Tokyo Marui Vz61 Scorpion AEP. As the internals are those found in AEPs, this is powered by a 7.2v Micro X Battery just like the battery used in the Marui MP7 AEG. For this video, Mach Sakai checks it for operation, externals, and accuracy.
Another Jing Gong AEP gets the attention from Airsoft Atlanta for a review... "The JG Scorpion VZ61 Full METAL AEP. This is a very small electric AEG Scorpion Russian style sub-machine gun! Modeled after the Tokyo Marui AEP. Full metal body and metal gearbox. Folding metal wire stock. Uses VZ61 AEP magazines only. Gun box includes AEP battery and charger. This is an authentic JG manufactured airsoft gun using the newest materials and components.
