A Friend bought a Brownell's 6.5 Grendel last spring. His barrel was set up with a fixed gas block and is not over gassed. My Friend didn't measure the gas port so I don't know if Brownell's specified a different gas port diameter. The Brownell's 6.5 Grendel II barrels are definitely rack grade so it's luck of the draw when it comes to accuracy.
