The Forster Headspace Gauge is a crucial tool for measuring the chamber length of a rifle, particularly important when chambering a new barrel or purchasing a used gun to ensure safety.
Made to SAAMI specs, the 6.5mm Creedmoor Field Gauge is precisely .0005 inch under 7.62 NATO NO-GO dimensions for safety checks.
Forster's headspace gauges are machined steel and designed to be interchangeable across various calibers within the same stock number.
