Ok, I just got the sticker with correct markings, just one disappointment : the serial is 84-1044 everywhere... I don't care I'll get what I need to make it KV !
For the power I got confirmation that the NPAS and hop up chamber are the same as the PDW, so you may change them easily, there a little modification to do on the G39 but nothing hard.
Once I get the KV barrel (and know what inner barrel length I need) I'll install everything in there
EDIT :
And if my contact at H&K USA can score me a receiver, it's XM8 GBBR time MOUAHAHAHAHA !
EDIT 2 :
For RS parts here is a goodsite for getting some parts (already quick searched for G36) :
