Forster Products .308 (7.62 Nato)1.635'' Match Gauge Headspace Gauge Steel

The Forster Products .308 (7.62 NATO) 1.635" Match Gauge is a precision headspace gauge built for shooters and gunsmiths who need to monitor chamber wear on match-grade rifle barrels. If you're running a .308 Winchester or shooting high-precision rifles where chamber dimensions directly affect accuracy and case longevity, this gauge gives you the exact measurement tool to catch lug wear and dimensional creep before they become problems. Forster's match gauges are the standard in competitive and custom rifle shops because they're made to exacting tolerances and designed to survive years of heavy use.

This particular gauge measures 1.635" and is manufactured from hardened, ground high-speed steel—the same material you'll find in precision machine tools. That durability means it won't wear out or drift in dimension the way softer gauges can. Whether you're a competitive shooter monitoring your own chamber, a gunsmith fitting match barrels, or an armorer responsible for rifle maintenance, having a reliable headspace reference is non-negotiable when precision matters.

Forster manufactures these gauges in .001" increments across the full range from Go to Field, so if you need a specific dimension, they make it. This single gauge at 1.635" is one point in that spectrum—check what increment range you're measuring and order accordingly. The steel construction and precision grinding ensure repeatability over time, so you're buying a tool that will stay accurate through hundreds of measurements.

Frequently Asked Questions

What calibers does this headspace gauge fit?

This gauge is designed for rifles chambered in .308 Winchester or 7.62 NATO. It will not work with other calibers like .223 Remington or 6.5 Creedmoor.

How do I use a .001" increment headspace gauge?

Headspace gauges are precision measurement references used with a headspace comparator or in a rifle action to determine actual chamber dimensions. Each gauge in the Go-to-Field series represents a specific dimension; you use the appropriate gauge to identify where your chamber sits in the wear range. This single gauge at 1.635" is one point in that full spectrum.

Is this gauge suitable for match shooting and gunsmithing?

Yes. Forster match gauges are the industry standard for gunsmiths, armorers, and competitive shooters who need to monitor chamber wear on high-precision barrels. The hardened steel construction ensures accuracy and repeatability over extended use.
