- GO: Corresponds to the minimum chamber dimensions. If a rifle closes on a GO gauge, the chamber will accept ammunition that is made to SAAMI’s maximum specifications. The GO gauge is essential for checking a newly-reamed chamber in order to ensure a tight, accurate and safe chamber that will accept SAAMI maximum ammo. Although the GO gauge is necessary for a gunsmith or armorer, it usually has fewer applications for the collector or surplus firearms purchaser.
- NO-GO: Corresponds to the maximum headspace Forster recommends for gunsmiths chambering new, bolt action rifles. This is NOT a SAAMI-maximum measurement. If a rifle closes on a NO-GO gauge, it may still be within SAAMI specifications or it may have excessive headspace. To determine if there is excessive headspace, the chamber should then be checked with a FIELD gauge. The NO-GO gauge is a valuable tool for checking a newly-reamed chamber in order to ensure a tight and accurate chamber.

Works like there supposed to
After buying a Faxon barrel, BCG, brake and hand guard, I assembled them and shot about 350-400 rounds probably took me 30-40rds to dial it in, I started reading a lot of Negative experiences(a lot or most due to education level on this new caliber) I did a lot of research before investing but I certainly don’t know that much and some dumb things could just as easy happen to me. Either way be safe! So long story short I bought go no-go gauges so I could check my head space! And it’s good! Faxon barrel, Faxon bolt contributes to that imo. So check all you s-it and make sure you do a good through job. Buy go no-go gauges!
