Lyman 7705100 Pro Headspace Silver 223 Rem Stainless Steel

Lyman Pro Headspace Gauges have more features than any headspace gauge on the market! Inspired by Lyman Pro Die Sets, they are precision machined from corrosion resistant stainless steel for a long rust-free life. Outside flats prevent rolling and o-rings provide a non-slip grip. These gauges check maximum and minimum cartridge headspace and maximum case length, recommended for setting up sizing dies for bottle neck cartridges.
