"Early Type" M9 Hop Unit

[Cr0-Magnon]

I've just picked up a brand new but old style TM M9, with fixed hop. It's pretty and I was planning on putting a Guarder kit on it but doesn't even hop a 0.20g.

 

I was speaking to Luke @ Negative Airsoft yesterday and he says you can swap the whole unit for one of the Gen.1's, with grub screw hop adjustment. However he wasn't sure if you could use a unit from the Gen.2 (ie the wheel adjustment).

 

Does anyone here know?

Have you managed to get somewhere with it?
