Proper gas port size for a 10.5" barrel?
I jsut received my tax stamp for an SBR and now shopping for a 10.5" barrel. I am getting different gas port sizes and was wondering if there was a "standard" gas port size for a 10.5" barrel?
I was looking at a used Compass Lake barrel which has .069-.073 gas port size.
Spikes tactical mentioned they have gas port size between .073-.089 in size.
ADCO said they can do any size.
I am leaning towards ADCO barrels since they have a decent reputation and good bore concentricity. (Plan on using a suppressor in the future) They also come crowned and "machine gun grade".
