If the T99 barrel hole dia for gas porting and the 5 hole dias in the gas adjustment spindle can be measured without a lot of trouble, would one of you mind either posting or emailing me the measurements? I need those dimensions as a reference for calculations on another project I'm going to start later this year. I know it's hard to measure small holes without the right tools, but all I need to know is the largest size bit, for example, the holes will pass. That'll get my project started. No matter what, I still have to do the CFD analysis. Thanks!
