I wrote down all the specs on that BCM barrel when I did the build but it's on a yellow legal pad somewhere. I need to find it and put all those specs in my database anyway so I'll see if I can find it tomorrow.
Your gas block seat might be .625" (aka 5/8"), there's no way in hell your gas port is 5/8".
