Military Blog JP posted a YouTube video of the new Tokyo Marui MP7A1 Gas Blowback on display during the Shizuoka Hobby Show held early in the middle of this week. The firing and blowback sound crisp and of course a a cute Japanese girl firing it makes it even sweeter. More of Shizuoka Hobby Show at Military Blog JP.
Here's another one from Hyperdouraku.
