Hi everyone. When I got my mini gs, it was slightly used (1-2 cases of paint) in the beginning of summer. Have put around 10-15 cases since then. Everything is stock. Love the marker, shoots smooth and extremely quiet. The only problem I have had since the beginning is the velocity seems to be capped at 270ish fps. It seems to be a rather popular problem and I have read many posts about it, but still decided to make my own post. Best operating pressure so far seems to be a bit over 200psi. Things I have tried so far: cleaning and relubing bolt and bolt guide cleaning and relubing poppet all orings seem fine different tanks (73/45 dye ul with inspire hp reg and some zen steelie 48/30 with hp output) fresh duracell batteries dwell is set to 5ms if im not wrong (was planning on resetting to default settings) It is not a major setback, but it would be nice to get the maximum performance out of my marker. Any help would be much appreciated.
