DESCRIPTION
The Forster NATO Maximum rifle chamber gage checks to see that the rifle does not have excessive headspace, which could lead to dangerous pressure problems.
There can be great differences between the chambers of military rifles based on the type of action (FN, Garand, Ishapur, etc.) and also based on the amount of use the rifle has seen.
For any gunsmith or armorer working with military firearms in these two calibers, these NATO Headspace Gages can make a huge difference in both performance and safety. Note that the 7.62 NATO Headspace Gages do not conform to SAAMI tolerances.
