The Forster 6.5x55mm Swede No-Go Gauge (brand part no. HG6555N) is a precision steel headspace gauge that checks for a 6.5x55mm Swedish Mauser chamber cut too deep during barrel fitting or rebarrel work. Forster Products machines it to a fixed 1.788-inch length marking the upper edge of acceptable new-build headspace; if the bolt closes easily on this gauge, the chamber needs correction before the rifle is fired. Used with a go gauge, it brackets the safe headspace range for this classic Scandinavian cartridge during a rebuild. Add it to the rest of our gunsmithing tools and gunsmith supplies for surplus rifle rebuild work.
