| I never checked headspace on my builds that are the same manufacturer parts. When i use different manufacturers for parts i like to. Now days i doubt you will ever have headspace issues on new parts. I started checking mine and own a set of headspace gauges. I think Ar15 owners should at least know how to check headspace, and, if nothing else, its good reassurance that your in spec. |

The only one I ever had an issue from I bought the bolt and barrel from the same vendor/maker.
I nice lightweight chrome line barrel and a nice chrome bolt/carrier. Very tight headspace. Wouldn't chamber some of my reloads that my other ARs ran with no issues and would sometimes blow a primer out of the primer pocket and jam the trigger/hammer up in the lower. Check it, found it would close on the go ga, but just barely. Got my "loose" 20" A2 flat top out and swapped bolts with it and had no more issues with it. I check mine now. |

Check it. Be sure. Be safe. +1 I just got my third XXX BCG and the bolt failed the No-Go check on two new 300 BO barrels and four new 5.56 barrels. The vendor is sending me a new bolt - good customer service  .
If I had not checked I would not know I had an out of spec bolt. |
| I check for excessive head space with a field gauge for safety on my cheap rifle that I screw around with. My good rifle has a matched bolt that was checked by the barrel maker. If I was dealing with a $300+ barrel and other expensive parts, I would invest in the gauges. With $100 barrels and $80 bolts, I'm satisfied with the field gauge. |

More than $25? |

Headspace is a measurement of the relationship between the bolt and in the barrel. Nothing outside of that. Personally, If I was just putting together a .223 plinker and I wasn't reloading....meh. Because I reload, though, I care about how much stress the brass undergoes, so I check. In your case, I would say that if you're worried enough to ask the question, then check headspace. If for no other reason, than just to give yourself the piece of mind. |
| Check it before you assemble the barrel. Strip the bolt and drop in the Go gauge. Put the bolt in the barrel extension and rotate it with your fingers. You can feel it if its loose. If your a cheap skate you can put a couple of layers of masking tape on the end of a Go gauge. It the bolt closes on that you might have a problem. If the bolt doesn't rotate you should be good to go. |
