Overview

The Forster .22-250 Remington SAAMI Dimensioned No-Go Length Rimless Headspace Gauge is a precision measurement tool designed for gunsmiths and reloaders to verify chamber dimensions and ensure firearm safety. Crafted from A2 tool steel and held to extremely tight tolerances within 0.00015 inches, this gauge helps determine whether a rifle chamber has excessive headspace. The No-Go gauge is sized to the upper tolerance limit for chamber length (1.579 inches). If a rifle chamber closes on this gauge, it may indicate excessive headspace, signaling that the firearm should be inspected before firing. It is an essential bench tool for chamber work, barrel installations, and quality control during precision reloading.
