A quick follow up. I did have to drill the gas port to .093 and use a light buffer to get it to run. I don't remember the buffer weight, it is out of my 300 Blackout. The adjustable gas block is wide open.
I may run it like this a while and brake it in, then go one bit size larger and tune the gas if the regular buffer is too heavy.
