So that means that if you already have a large gas port, it will only get bigger!
The next question is, what can we do to help bleed off some of the excess gas and slow things down a bit? One of the things I like to do is switch out the bolt carrier to the LMT enhanced carrier (notice I did not say enhanced BCG). The LMT enhanced carriers have 3 gas vent holes. This seems to help get rid of some of the extra gas. The other thing you can do is try an H2/H3 buffer and a CS buffer spring (one or the other or combination of the two). You should also make sure that you are running a stiff extractor spring and a Crane O-Ring to help with extraction.
