I saw this video on the Orange Mod Works Facebook page. From the sounds of it, it's a flywheel blaster with a fully automatic dart pusher.
The rate of fire is absolutely ridiculous, and while I'm unsure if this particular one has been modified, I'm hoping that it isn't. Rapid Strike CS-18 Firing
Hope this isn't breaking any rules.
EDIT: The website is in Chinese but the video should play automatically.
