Forster Headspace Gage .223 Rem No Go 1.467

The Forster Headspace Gage .223 Rem No Go 1.467 is a precision measurement instrument designed for reloaders, gunsmiths, and ammunition manufacturers who demand exacting chamber specifications. This NO GO gage establishes the maximum allowable headspace dimension for .223 Remington cartridges, ensuring that rounds will not chamber in any firearm with a chamber larger than the gage's specification.

Manufactured to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications, this gage features precision-ground steel construction that guarantees repeatability and durability under field conditions. The NO GO gage measures 1.467 inches and is used in conjunction with a GO gage to establish the acceptable headspace window; ammunition that chambers over the NO GO gage is out of specification and must be rejected.

At just 0.12 lbs and compact dimensions (2.75 x 0.95 x 3.4 inches), the gage fits easily into a reloading bench setup, ammunition inspection kit, or armorer's toolkit without taking up significant space. The hardened steel construction resists wear and maintains dimensional accuracy through thousands of quality checks, making it essential for maintaining safety and reliability standards in professional and competitive environments.
