The NO GO Gauge by MANSON PRECISION is designed to ensure firearm safety by checking that the chamber headspace does not exceed the SAMMI-recommended maximum depth.
It is crucial to use headspace gauges from the same manufacturer to avoid tolerance stacking and ensure accurate measurements.
The gauge is made from M7 high speed steel, is in-the-white, hardened, and specifically fits the 9 mm Luger cartridge.
