The Forster Rimless Headspace Gage GO length is designed for 30 Carbine with part number HG0030G. This gauge provides the only accurate way to measure and test the length of the rifle chamber, and is essential when chambering a new barrel to ensure a tight, accurate, safe chamber. Ground to an exacting ±.00015″ headspace tolerance to ensure accurate testing of a rifle’s chamber, this precision-ground tool is manufactured from top-quality, hardened steel and made to SAAMI specs.
The GO gauge corresponds to the minimum chamber dimensions, and if a rifle closes on it, the chamber will accept ammunition that is made to SAAMI maximum specifications. This gauge is essential for checking a newly-reamed chamber in order to ensure a tight, accurate, and safe chamber that will accept SAAMI maximum ammo. When you buy a used gun, always check the headspace before firing. The compact design allows you to avoid the need to take the bolt apart, making this an indispensable tool for gunsmiths, armorers, and serious shooters who demand precision and safety in their rifle chambers.
