I SEARCHED A LITTLE BIT, I WILL ADMIT, NOT A LOT.
MY QUESTION IS for instance, a bolt for an AR.... specs will say .223 .556 and 300.
what about head space when checking with the guages? i.e. go, no-go, field.
won't you run into issues there like different results?
please forgive me if it's been asked a million times.
thanx

All three of those calibers use the same basic AR15 bolt.
They all use their own headspace gauges as well. In a 5.56 chamber/bolt combo you would check headspace with 5.56 headspace gauges, it's caliber specific not bolt specific.
Think about a Remington 700 rifle with a standard 308 bolt face in it.... can chamber probably 100 different calibers with that one bolt, but you would always match your headspace gauge to the chamber of your barrel.
Sorry if I misunderstood the question.
