Forster Headspace Gauges are essential for checking the chamber length of rifles to ensure safety and accuracy, especially when chambering new barrels or purchasing used guns.
The gauges are made to SAAMI specs with the 22-250 Remington Field Gauge being .0005 inch under 7.62 NATO NO-GO dimensions for safety.
These machined steel gauges are caliber-specific but some are interchangeable within a given caliber family, as indicated by the same Stock #.
