The Forster 284 Winchester No-Go Gauge (brand part no. HG0284N) is a precision steel headspace gauge that checks for a 284 Winchester chamber cut too deep during barrel fitting. Forster Products machines it to a fixed 1.815-inch length marking the upper edge of acceptable new-build headspace; if the bolt closes easily on this gauge, the chamber needs correction before the rifle is fired. Used with a go gauge, it brackets the safe headspace range for this short, fat-bodied cartridge during a rebarrel or custom build. Add it to the rest of our gunsmithing tools and gunsmith supplies for precision rifle work.
