Absolutely Essential For Accurate, Safe, Chamber Work
The only way to accurately measure and test the length of the chamber of the rifle. Essential when chambering a new barrel to ensure a tight, accurate, safe chamber. Whenever you buy a used gun, always check the headspace before firing. Gauges are etched with “Go” or “No-Go” and caliber/gauge name for easy identification. Both Forster and Clymer gauges are made to SAAMI specs.
