Is headspace not an issue when building an AR with all new parts? I see some manufactures offer headspaced bolts that are supposed to be matched to the barrel. Is this neccessary or can any bolt be used without issues, therefor eliminating the need for a headspace gauge?</div></div>
No, you should always check headspace.
I think what Mr. Seekins was referring to was if the barrel was already chambered and had an extension installed there was no headspacing to be done without a smith or some tools and a little know how.
I generally buy barrels with matching bolts to eliminate this need. But then again I also refuse to use the same bolt with different barrels because of wear pattern differences.
