The Forster .308/7.62 NATO 1.632-Inch Match Gauge (brand part no. HG308-1.6320-SP) is a precision steel headspace gauge ground to a specific 1.632-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

Where does 1.632 inches fall in Forster’s .308 gauge series? It sits toward the shorter end of the fine-graduated match gauge lineup, closer to typical go-gauge territory than the longer no-go steps.

Do I need the entire series, or just one gauge? Most handloaders buy just the step or two closest to their known chamber dimension rather than the full series.
