7.62X39 GO NO-Go Set MADE IN USA

Headspace gauges from precision ground hardened US steel to SAAMI’s ANSI tolerances. Headspace is the distance between breech face and the base of the cartridge when the action is closed. It is best to remove the extractor, ejector, and firing pin from the bolt to achieve optimal results when checking headspace. The use of both GO and NO-GO headpsace gauges is essential for all newly reamed chambers or a newly installed barrel to a trunnion . This ensures a safe and accurate chamber that will accept SAAMI maximum ammo. Warning – Never force an action closed on any gauge.
