What size gas port for this 16? BA Hanson barrel

[VASCAR2]

You can try it without the O ring but some of the 6.5 Grendel extractors need to be polished around the corners. Some extractors leave fang like marks on the rim of the brass.

Here is are links to a thread discussing polishing extractors.
