Forster Products NATO Chamber Headspace Gage, Rimless, Hardened Steel, Precision Ground
Product Features
- 7.62 NATO CHAMBER HEADSPACE GAGE: The proper use of Headspace Gages is the most reliable way to test rifle chamber length. These rimless chambers require a slightly longer maximum headspace than commercial 308 Win calibers. The 7.62 NATO Headspace Gages do not conform to SAAMI tolerances.
- MAXIMUM LENGTH: 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. The NATO Maximum Headspace Gage measures 1.6455"
- PRECISION MACHINED: Manufactured from top-quality, hardened steel and precision ground to ANSI and SAAMI tolerances. Headspace tolerance ground to a very exacting .00015.
- QUALITY ASSURED: Each Headspace Gage thoroughly inspected with NIST-certified measurement tools to ensure the highest quality product.
- MEASURING MEANINGFUL HEADSPACE: Properly speaking, and for safety purposes, one measures headspace as the difference between the length of a standard cartridge, as represented by a gage, and the guns actual chamber length , when the head of the cartridge is flush against the bolt face.
