The Forster 284 Winchester Go Gauge (brand part no. HG0284G) is a precision steel headspace gauge sized for the 284 Winchester, a short, fat-bodied cartridge favored by some precision and hunting rifle builders. Forster Products machines it to a fixed 1.81-inch length representing the minimum acceptable headspace; the bolt should close freely on this gauge in a properly finished chamber. It’s the baseline half of a standard headspace check, used alongside a no-go gauge during a new build or rebarrel. Stock it with the rest of our gunsmithing tools and gunsmith supplies for precision rifle work.

Frequently Asked Questions

Why is 284 Winchester’s fat case shape relevant to headspace checking? Its short, wide body still relies on precise shoulder-to-bolt-face headspace like any other bottlenecked cartridge, so the same go/no-go check applies.

When would a builder need this gauge? Any time a 284 Winchester barrel is fitted or a chamber needs verification during a custom build.
