Pulled the FSB and the gas port hole in the barrel is .093". I keep seeing it is supposed to be .0625" on a 16" barrel with carbine length gas system. If that is correct then I am about 50% oversize and it would have significantly over pressure not under so don't understand the weak ejection. Double checked the ejector spring vs. a new one and it's good.
