My vmach piston was around 240g. The one phil made is around 130 I think. It's been a while. It was spot on in naked form but running at 740 with express so it needed some better sealing. Which gave us more power than we knew what to do with so it took us time to get it back down. But boy was it sweet at 740. It was practically recoiless. Think we got the balance just spot on. Just not the power.
