Forster Products No-Go Gauge Features The Forster No-Go Gauge is machined to precise SAAMI specifications for the .280 Remington cartridge letting gunsmiths verify that a chamber has not been cut beyond its maximum recommended headspace. In a correctly chambered rifle the bolt should not close on this gauge and if it does the chamber may need further inspection or correction. Used alongside a Go gauge the No-Go gauge lets a gunsmith fully bracket the acceptable headspace range during a chambering job. Hardened steel construction ensures the gauge holds its precise dimensions through repeated use on the bench. At just over 2.1 inches long and roughly a tenth of a pound the No-Go Gauge is compact enough to carry alongside a full set of gauges in a gunsmithing kit. Confirming proper headspace is essential to safe and reliable function since excessive headspace can lead to case stretching ruptures or premature wear on the action. This gauge gives gunsmiths and serious reloaders a dependable way to confirm a .280 Remington chamber falls within safe limits before it is returned to the customer or put back into service. A precise tool like this Forster No-Go Gauge is a worthwhile addition to any chambering or inspection toolkit.
