You are loosing a little area because of the 3mm pin so without calculations I think this would make it close to the 6.35mm (1/4") that I drill the transfer port and barrel port to. The peek actually needs less force to open it because the pressure doesn't deform it when sealed. 90's wod be awesome.Yes I went to 5.9mm with the stock poppet. I would be interested to see the results of a custom poppet and 7mm port. Though I wonder if the transfer and barrel port will be able to flow the same. I believe 90 FPE may be achievable however it's possible a heavier hammer may be needed. Just speculation though.
