Forster Headspace Gauges are crucial for measuring the chamber length of rifles to ensure safety and precision, especially when chambering new barrels or purchasing used firearms.
The gauges are manufactured to SAAMI specifications, with the 222 Remington GO Gauge being 0.0005 inch under 7.62 NATO NO-GO dimensions for safety.
These gauges are machined steel and are designed to be interchangeable across various calibers that share the same stock number.
