I will soon be replacing my current barrel with a new barrel. I'll be using the same bolt & carrier with the new one as I have been with the old one. Does anyone have any idea of how often headspacing issues come up when swapping out barrels of AR-15s? Is this typically a concern, and would it be considered highly unwise to swap in a new barrel without checking the headspace with a field gauge? |

AR barrels are headspaced when made and barrel extension is fitted. So the real variable is your used bolt. How much is it worn, under spec or over spec. Even though I have no proof, I like a new bolt to go with my new barrels. Carrier's I just measure them and as long as they provide a good fit for bolt with new gas rings I run them. |
| I have had four barrels that were trouble to get a GO gauge to close on. Three I worked out by swapping bolts untill I found one that would close. One barrel I had to send back to the manufacturer because I could not find a bolt that would close on the gauge. I have not had one yet that had to much headspace. |
