.... a while back in a conversation with an acquaintance, he was of the opinion that with AR15's being "standardized" gauges were an unnecessary expense. My response was that for the avg cost of $30-$45 per gauge, it was cheaper than the cost of a new bolt, or worse yet a complete BCG or barrel extension, especially when you factor in the shipping, labor and time costs. Factor in ammo or component costs used during testing and that amount increases. For a person that is fortunate enough to be able to afford swapping barrels or complete BCG's it's another tool for problem mitigation.
...when asked, especially by someone less mechanically inclined or lacking the proper tools, I typically recommend that when a vendor offers a barrel with a headspaced bolt or complete BCG, that the combo be purchased as it implies that whatever warranty the barrel vendor offers would be honored if issues are found. If the barrel vendor has a specific MOA guarantee, proper headspacing does have an effect on attainable accuracy even if "match grade" shelf ammo is used for that accuracy testing.
...just my $0.02
