Mangudai

What anyone remember this gun. I know somebody who still ahs theres. Its about 5 years old, I think older but I shot and its a nice gun. But then again ive only shot a victor 2 lol. This seems like a gun that ppl would remember so i was wondering if anyone knew what I was talking about. I was looking to sell me this like...150 oz refil lstation thing with the gun, ghille suit pieces, thermal mask, hopper 20 oz tank with on/off valve for $200 but im not sure if im reading to pay that much yet.

Its a really cool gun but I doubt I can afford it.
