Is the barrel dimpled for a gas block, or drilled for a cross pin?
Did you actually measure the gas port? I measure the port on every barrel I get my hands on, instead of relying on what it’s advertised to be. All manufacturers make mistakes.
I have gas port alignment pin sets I use when installing gas blocks, to ensure they’re aligned properly.
Losing gas at the gas key on the BCG is another possibility.
