Forster 6.5x55mm Swedish Go Gauge Headspace Gauge

The Forster 6.5x55mm Swedish Go Gauge Headspace Gauge (brand part no. HG6555G) is a precision steel gauge from Forster Products used to verify minimum headspace on a 6.5x55mm Swedish Mauser chamber before a rifle is put into service. A go gauge should chamber and let the bolt close on a properly cut chamber; if the bolt won’t close on it, headspace is too tight and the chamber needs further reaming. Gunsmiths and serious hand-loaders use gauges like this one after barrel fitting, chambering, or rebarreling work to confirm a safe, in-spec chamber before firing the first round.
