I recently picked up a WE M9 in-store last week whilst I was in the Midlands for a week and away from home, and got to try it out on Sunday.
As I use 0.3s, I'd obviously need to add more hop to it, so on stripping it down to adjust the hop I saw that the hop unit was a different design from anything I'd seen before (shown below). And on adjusting hop then it was having no effect, nothing was protruding into the barrel as one might expect.
After doing a bit of reading, am I correct in thinking that this is the Gen 1 version?
According to my PayPal statement, then it was down as a gen 2 (which iirc uses the more common style hop unit, with the standard TM compatible pistol/VSR buckings).
Has anyone had any experience with the WE M9 and Von confirm that I'm correct in thinking that the gen 2 should have a TM compatible unit and this has been mislabeled when sold?
