    ...Ahh, the simplicity and precision of fixed port sizes...

    Clint, there is a pretty good chance I'll be replacing this block with one of yours eventually but I either hadn't found them or they were out of stock when I was scrounging for parts earlier this month. In the mean time I hope to learn something about gas levels from the use of an adjustable block.

    The Faxon 16" pencil is an outstanding barrel. Incidentally, I have an adjustable gas block on that gun.
