Just an update guys, I have a kA ultra grade M4 with GHK gas conversion. It was delivered in poor condition loose parts etc.
Anyway after a good deal of changing seals, still no charge until I removed the nozzle carrier and tighten the screws holding the carrier together, followed by removing the protruding threads and greasing. I now works well.
Hope this helps anyone else having a similar problem.
