Forster Products Headspace Gage (FIELD Length Rimless)

Headspace Gauge Features

Because your safety is on the line, Forster Headspace Gages are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifle’s chamber. If a rifle closes on a GO gage, the rifle chamber will accept any ammunition that is made within S.A.A.M.I. (industry standard) specifications. If a rifle closes on a NO GO gage, the rifle chamber might have excessive headspace. Most gunsmiths chamber a rifle’s headspace between the GO and NO GO dimensions. If a rifle closes on a FIELD gage, the rifle chamber is dangerously close to or already over the S.A.A.M.I. specified maximum chamber size.
