How do you set, determine and check the correct headspace when installing a barrel on an
AR-15/M-16 receiver?

Use a headspace gauge. [:)] You can't set the headspace. That's the beauty of the AR. It's determined by the bolt and the barrel extension, at the factory. If the bolt & barrel are new you're good to go. (But it's a good idea to check, just in case somethings out of spec.)
