Isn't FAL head spacing set by a pin in the receiver? Changing the head spacing is as simple as swapping out that pin for one of a different thickness? I think you can buy the pins and specify the pin thickness?
Yes. Headspace guages, use brains and math (or feeler gauges, etc) to figure out how much more or less is needed, get a new one installed. Of course, a whole set of them at an experienced smith can do this in minutes without thinking
Good example of how the FAL is not harder to do than the AR, just different. Mine has been apart, completely, several times. So easy to do that when it's time to eg. refinish: just pull it all apart. If you follow procedures well, it barely even needs to be re-zeroed.
So used to that I have only in the last few months really gotten my head around the AR enough to be comfortable doing the same, and re-barreling (or changing barrel nut for rail reasons) just cause I have a spare 20 minutes.
