The RIMLESS CARTRIDGE HEADSPACE GAUGES by MANSON PRECISION are designed to ensure safe firearm operation by providing SAMMI-recommended headspace dimensions, with the GO gauge indicating minimum chamber depth.
Mixing and matching brands of headspace gauges is not recommended due to tolerance stacking, which can lead to inaccurate readings; it's best to use gauges from the same manufacturer for consistency.
The product is made from M7 high speed steel, is in-the-white, hardened, and specifically tailored for the 50 BMG cartridge, ensuring durability and a long service life.
