| This might be a stupid question, but I want to get this right. Found a great deal on a Noveske SPR barrel w/ lo-pro gas block and tube. It did not come with the properly spaced bolt like others do. If I buy a Noveske BCG, should I be ok with headspace without buying go no-go gauges? |

Even the best manufacturers make mistakes.
My gages have more than paid for themselves by the problems they have caught. Bolts have manufacturing tolerances. A person can find as much as a .002” difference in headspace by using a different bolt with a barrel. I have found several barrels that failed Go gages. The military has Go and No-go specs for new weapons. The No-go spec of 1.4706” is set so a weapon can fire a minimum of 6k rounds before failing the Field gage. |

So if you were to buy 1 gauge for a new build, go or no-go? |

It USED TO BE that buying from good companies was enough to be sure, but now there are all sorts of manufacturers that sell to all sorts of vendors, and even the "good companies" might wind up with out of spec stuff. It's ALWAYS best to check. |

For instance the No-go gage is a reject point for a new barrel. |
