G&G ARP9 met upgrades. (Mosfet, motor, hop up etc etc)

I haven't played airsoft for a few years.
And now I have made the choice to sell some of my collection.

This G&G ARP9 includes the standard mid cap and a drum magazine from G&G.

Internally, there is almost no stock left.
As far as I can remember (and looked up using old order emails), it contains the following:
Tienly GT 30000 (30,000 rpm engine)
Perun mosfet
Maxx hop up
R-hop patch
SHS 8mm bushings
SHS 13:1 super high speed gear set
Full steel 14-tooth piston
Upgraded barrel
Polycarbonate ventilation piston head
Stainless steel M4 nozzle
Cylinder head

As can be seen in the photo of the chrono, the replica is working and shoots properly.
