Using a SLR adjustable block, set to hold the bolt open on empty mag, and brass is dropping at 3:30-4 o'clock.
Didn't think to try and measure the port while I had everything apart.
Gas is mid length.
No suppressor.
I believe that the buffer and spring are standard carbine.
Thanks for taking the time to help.
