Forster Headspace Gage .22-250 Rem - No Go 1.579

The Forster Headspace Gage .22-250 Rem – No Go 1.579 is a precision measurement tool designed for gunsmith chamber verification and reloading quality control. This tool is essential for anyone performing chamber work, barrel fitting, or precision reloading with .22-250 Remington rifles.

Headspace—the critical distance between the breech face and the cartridge base when the action is closed—directly impacts both safety and accuracy. The No Go gage establishes the upper tolerance limit for chamber length, ensuring fired brass remains fully supported inside the chamber walls. Forster Products manufactures this gage to tight dimensional tolerances (1.579-inch specification), allowing it to function as the definitive go/no-go standard for .22-250 chambers.

Gunsmiths rely on headspace gages during barrel installations and chamber reaming to confirm proper dimensions before returning a rifle to service. When used in conjunction with a Go gage, these instruments provide the complete picture of chamber condition. The compact design (3.05 x 0.85 x 3.2 inches) makes it practical for bench work, gunsmith operations, or reloader's benches where space and precision matter.
