Forster Headspace Gauges are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifle’s chamber. The NO-GO gauge corresponds to the maximum headspace recommended for gunsmiths’ chambering new bolt-action rifles, and if a rifle closes on this gauge, it may still be within SAAMI specifications, or it may have excessive headspace. This 284 Winchester NO GO gauge measures 1.815″ in length and is manufactured from hardened steel, precision-ground to ensure reliability when setting headspace during barrel installation.
Headspace is the distance between the face of the breech and the base of the cartridge when the action is closed, and excessive headspace can be dangerous as well as impair accuracy. The NO-GO gauge is recommended only for setting the headspace on a bolt action barrel installation, not for checking headspace on already assembled guns. 284 Family gauges work on 284 Winchester, 22-284, 6-284, 25-284, 6.5-284 Norma, 270-284, 30-284, and 35-284.
Essential for gunsmiths, armorers, and serious reloaders, this Forster precision gauge helps ensure safe, accurate chamber specifications. Forster gauges are made to SAAMI specs, providing the confidence that your rifle is properly chambered. A critical tool for any gunsmith’s collection.
