I am up to 165 rounds now without a single malfunction of any type since reducing the gas port. No more stovepipe jams, no faulty ejection, nothing. Just runs like a sewing machine! Even though it worked well with the .063" gas port I added an H buffer and a Sprinco extra power buffer spring and both made it cycle even smoother and more consistent.
