300 BLK Port Size Testing

hey thanks! great link and some interesting reading...... my conclusion for my set up is that according to that my port should be big enough @ 0.112 suppressed, but I'm thinking of drilling out to 0.125 anyway (as 300_BLK has advised) and run an adjustable gas block if I need to reduce gas for the super loads.
