The Forster 6.5x55mm Swede Field Gauge (brand part no. HG6555F) is a precision steel headspace gauge built to check whether a 6.5x55mm Swedish Mauser chamber has worn past a safe service limit. Forster Products machines it to a fixed 1.793-inch length representing the maximum acceptable headspace, a step beyond the tighter go/no-go range used for new-build inspection. Given how many Swedish Mauser actions still in circulation date back decades, a field check like this is a sensible step before putting an older rifle back into regular use. It pairs well with the rest of our gunsmithing tools and gunsmith supplies for anyone servicing period military rifles.
