This issue happens with m3 power block, yes it happens with older varients but with only first few shots. Fx keeps missing around with every new variation of the impact.

M3 - friction in the hammer/valve system
- Thread starter TDK
- Start date
@Vetmx thanks for the details. I can never get enough data points.
@bigHUN @Scotaty Thanks for the polishing info. That's exactly what I had in mind, so good to hear it will improve things.
@Stubbers . Dimensional tolerance variation is a good theory. Considering that the design seems borderline with the backing for that PUR 90 oring, maybe some variance in the plenum front end (E101) and/or valve-rod diameter results in some guns being more picky than others. Hopefully the polish and oring replacement works and I don't have to go down the parts swapping route.

Using a peek spacer at tighter tolerance and a viton oring in front of it takes care of it or I know mubaur was offering a different end cap for the 720 plenum that took care of the problem as well I don't know if it's still available though
