Product: Forster Products 223 Remington NOGO Headspace Gage Forster Products manufactures precision headspace gages to maximize safety and accuracy in your rifle. These gages are necessary when finish chambering a barrel, or when checking the chamber of a used gun to be sure the headspace dimensions are within safe limits. These gages are held to tolerances within 0.00015" to ensure accurate testing of your rifle's chamber. NO-GO: Corresponds to the maximum headspace we recommend for gunsmiths’ chambering new bolt-action rifles. This is not a SAAMI-maximum measurement. If a rifle closes on a NO-GO gage, it may still be within SAAMI specifications, or it may have excessive headspace. To determine if there is excessive headspace, the chamber should then be checked with a FIELD gage. The NO-GO gage is a valuable tool for gunsmiths’ reaming new chambers, in order to ensure tight and accurate headspace. Forster Products
