Forster Products manufactures precision headspace gauges to maximize safety and accuracy in your rifle, and these gauges are necessary when finish chambering a barrel or checking the chamber of a used gun to be sure the headspace dimensions are within safe limits. The 280 Remington No-Go Gauge (HG0280N) is an essential tool for gunsmiths and serious shooters who demand accuracy and safety when installing new barrels or verifying chamber specifications.
Machined from A2 tool steel, these gauges are held to tolerances within 0.00015″ to ensure accurate testing of your rifle’s chamber. The gauge is ground to an exacting ±.00015″ headspace tolerance to ensure accurate testing of a rifle’s chamber, carefully inspected with NIST-certified measurement tools, and made with painstaking care and rigorous manufacturing standards.
The No-Go gauge corresponds to the maximum headspace Forster recommends 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. The NO-GO gage is a valuable tool for gunsmiths reaming new chambers, in order to ensure tight and accurate headspace.
