The Clymer 300 AAC BLACKOUT GO GAUGE is essential for measuring the chamber length of a rifle, crucial for safety and precision when chambering a new barrel or buying a used gun.
These gauges are clearly etched with "Go" or "No-Go" and the caliber/gauge name, made to SAAMI specs, and are interchangeable between calibers with the same stock number.
Made of machined steel, the size of the gauge varies with caliber and style, and the product line includes gauges for a wide range of cartridges beyond just the 300 AAC Blackout.
