The HEADSPACE GAUGES are essential for measuring chamber length to ensure a safe, accurate, and tight chamber, especially when chambering a new barrel or buying a used gun.
Forster Products' gauges are made to SAAMI specs, with the .22 Long Rifle GO GAUGE being .0005 inch under 7.62 NATO NO-GO dimensions for safety.
The gauges are machined steel and interchangeable between calibers that share the same Stock #, with specific gauges available for a variety of cartridges including .30-30, .30-06, and Magnum Cartridges.
