Forster Products .308 (7.62 Nato)1.636'' Match Gauge Headspace Gauge Steel

The Forster Products .308 (7.62 NATO) Match Gauge is a precision headspace measurement tool built for shooters who need exact chamber dimensions on match-grade rifles. Whether you're a competitive rifleman, armorer, or dedicated reloader, this hardened high-speed steel gauge lets you track locking lug wear and chamber growth with the kind of precision that keeps a match barrel performing at its best. At 1.636″, this specific gauge fits into Forster's comprehensive .001" increment system—so you can measure your chamber at Go, Field, and every critical step between.

Match shooting demands consistency, and consistency starts with knowing your chamber. This gauge gives you the data to catch wear before it affects accuracy, and to verify that a new barrel or rechambered rifle is cut exactly right. Unlike generic go/no-go gauges that only tell you pass or fail, Forster's precision increments let you track gradual changes over thousands of rounds—information that's worth its weight in brass when you're chasing tenth-of-MOA groups.

Built from hardened, ground high-speed steel, this gauge is made to last through years of regular use in the shop or at the range. It's the kind of tool that pays for itself the first time it catches a chamber that's drifted out of spec, or confirms that your freshly rebarreled rifle is cut perfect.
