The S200 has the same transfer port restrictor as all the other AA PCP's and yes, fully removed and blanked off with a stainless steel m3 button head cut to correct length (cut end polished).

I'm picking up some new springs later today. Perhaps the hammer spring is still set too high and causing hammer bounce and opening the firing valve more than once per shot?
