The OP's picture is the previous gen STP with sterling threads and IIRC the barrel OD is something like 7/8. I don't have a stock barrel hand to measure though.
Its the newer model STP, as for feed neck I will measure it here in a bit, I have replaced my feed neck alread with an after market one. I had an old BartPArts feed neck and turned off the threads on it and made it work, looks awesome will post pic's as soon as I find a camera to do so.
If you guys want anything else measured just let me know.
