it's an echo one but don't trip it's pretty much a we tech with better qc. armorer works is we with better qc so consider it armorer works I will sell for a good price but I want to trade the whole package for something I can use, ie not green gas powered and not hpa powered unless it comes with an airrig, comes with 3 short mags, 2 long mags and the gun, which has a wolf grey cerakote on the slide, and the taps cost me about $400 all together retail. trades I want specifically are: a good gearbox with a mosfet, all I really need is the shell and the mosfet tbh so if you want a good deal... some kind of good aeg maybe a unique aeg I'm really wanting a type97 all the sudden
