Product Overview

Necessary when finish chambering a barrel or when checking the chamber of a used gun to be sure the headspace dimensions are within safe limits. This is a Go Gauge only. Both a Go Gauge and a No Go Gauge are required to properly headspace a barrel. These Go Gauges represent the lower limit of SAAMI specifications for proper headspace dimensions. If the action closes with this gauge is inserted, then the firearm is within acceptable minimum headspace dimensions.
Go Gauge

  • Ascertains correct headspace dimensions by duplicating the minimum allowable distance, from the case head (or boltface) to the datum line of the cartridge's shoulder, allowed within the chamber to secure a loaded cartridge and allow the breech to be closed in a safe manner for firing.
  • If the firearm locks up in battery when the gauge is inserted, then it is within acceptable minimum headspace dimensions and may be used.
