Description
The Forster NATO Maximum chamber gage is a steel field tool designed to verify that a 7.62 x 51 NATO rifle chamber does not have excessive headspace. It is intended for use by gunsmiths, armorers, and qualified personnel working on military-pattern rifles where NATO headspace dimensions apply. The gage helps identify chambers that exceed acceptable maximum dimensions for currently manufactured NATO ammunition.
