Forster Headspace Gauges are essential for ensuring a safe, tight, and accurate rifle chamber, especially when chambering a new barrel or buying a used gun.
The 6.5 PRC Field Headspace Gauge is made to SAAMI specs and is .0005 inch under 7.62 NATO NO-GO dimensions for safety.
Gauges are machined steel, vary by caliber and gauge style, and are interchangeable between calibers with the same stock number.
