The Forster Headspace Gauges are essential for checking the chamber length of rifles to ensure safety and accuracy, especially when chambering a new barrel or purchasing a used gun.
Made to SAAMI specs, the 30-40 Krag GO Gauge is specifically designed for the 30-40 Krag cartridge and is .0005 inch under 7.62 NATO NO-GO dimensions for safety.
The gauges are machined steel and can be interchangeable among various calibers that share the same stock number, providing versatility for different cartridge measurements.
