I am bumping this thread because I have had it come up on searches a couple times.
The IWI Zion 12.5” midlength has a .085” gas port after about 3-500 rounds of use.

My homemade 12.5" mid length, 14.5 BCM cut down, has a .055 vented setscrew in the front sight base and runs 100% suppressed with a YHM turbo3. I use a standard spring and H buffer. Very smooth with very little gas to face.
Geissele's new 12.5" CHF barrel has a gas port of .070

edited to reveal that I didn't read the title of the thread as this is a carbine length gas system barrel. :/
Considering my 13” will function with Wolf Gold and a .0625 gas port…yeah.
