Forster Headspace Gauges are essential for ensuring the safety and precision of rifle chambers, particularly when chambering new barrels or purchasing used guns.
The gauges are manufactured to SAAMI specifications and the 30-06 Springfield Field Gauge is made to be 0.0005 inch under 7.62 NATO NO-GO dimensions for safety.
These gauges are machined steel and interchangeable between various calibers that share the same stock number, including a range of cartridges from .25-06 to .35 Whelen.
