Ensure your safety and accuracy with the Forster Headspace Gage .303 British NO GO Gauge. Designed for gunsmiths, this precision tool measures the distance between the face of the breech and the base of the cartridge when the action is closed. Excessive headspace can be dangerous, leading to ruptured brass and compromised shooting performance. Made by Forster Products, this NO GO gauge is manufactured to exacting standards, ensuring reliable testing of your rifle’s chamber. If your rifle closes on a GO gauge, you can trust it will accept S.A.A.M.I. specification ammunition. Use this gauge to maintain safe headspace between GO and NO GO dimensions, preserving the integrity of your firearm.
