The Forster .308/7.62 NATO 1.631-Inch Match Gauge (brand part no. HG308-1.6310-SP) is a precision steel headspace gauge ground to a specific 1.631-inch step within the .308 Winchester/7.62 NATO match gauge lineup, used by precision handloaders and gunsmiths to pin down a chamber’s exact headspace rather than just confirming it falls between go and no-go. Forster Products offers this cartridge in a series of fine-graduated match gauges spaced a thousandth of an inch apart, letting a shooter set up ammunition to headspace precisely for their specific rifle. It’s a more specialized tool than a standard go/no-go pair, aimed at fine-tuning rather than pass/fail inspection. Stock it with the rest of our gunsmithing tools and gunsmith supplies for precision reloading work.

Frequently Asked Questions

Is a 1.631-inch gauge close to a standard .308 go gauge? It’s very close to the minimum end of the acceptable range, useful for chambers cut on the tighter side.

Can this gauge substitute for a standard go/no-go pair? It’s meant to complement rather than replace a standard pair, offering finer resolution once the broad pass/fail range has already been confirmed.
