I'm looking for a new Co2 blowback and I've come across this: Link

I'm linking to a google search as to not advertise any site in particular but any of the top hits get you the same gun.

I just want to know a little about this gun, the sites give very sparse info and youtube gives only a few vids in other languages. So it seems the publicity on this pistol is very light on the ground, anyone know why that is?

Does anyone know about this one or does anyone own it?
