Hi Iggy.
when testing the m4 is full assembled, all pins, mag release, buffer tube etc

I tried a different Mechbox incombonation with both upper hopups No change (unless you apply a little backward pressure then it works).
I think my problem Is the Upper receiver, its like it doesnt hold the hopup back far enough
for the nozzel to seal (its less then 1mm)

soo it the upper receiver
I used the upper from my M4 (the one that ususally runs the SystemAhopup assembly with the 455 Promy)
Put it on the JG lower -- 375 FPS all day long
So the upper us preventing the hopup from properly pressing against the bbs chase and Mechbox.
