10.5-11" gas port

[Ron458]

Ive looked through old posts & would like to confirm what the best gas port would be for an 10.5-11" brl running subsonics. I read .110 was a good size. Anyone have a brl this size that runs good with subs & would like to share the gas port size? Thanks, Ron

Good start,but other things like bore dia kick in.Douglass blanks are a hair larger and require a bit more opening.

I have a .102 port on mine but it may be a little closer to the chamber than perhaps your port will be. Safer to start smaller and work up if doing it yourself.

Roger that. I have one here that is .092 Think Ill start there & work up. Thanks Ron
