The HEADSPACE GAUGE is essential for measuring the rifle chamber length to ensure safety and accuracy, particularly when chambering a new barrel or buying a used gun.
Forster gauges comply with SAAMI specifications and the 222 Remington Field Gauge is specifically designed to be 0.0005 inch under 7.62 NATO NO-GO dimensions for safety.
Made of machined steel, the gauges are size-specific to caliber and gauge style, with some being interchangeable between calibers sharing the same stock number.
