Forster Headspace Gage .308 Win - No Go 1.634

The Forster Headspace Gage .308 Win - No Go 1.634 is a precision reloading tool designed for shooters and ammunition manufacturers who demand chamber accuracy and firearm safety. This No Go headspace gage serves as the upper tolerance limit for chamber dimensions, ensuring your reloaded cartridges or factory ammunition won't chamber in firearms with excessive headspace—a critical safeguard against dangerous pressure spikes.

Manufactured by Forster Products, a trusted name in reloading precision equipment, the No Go gage features a length specification of 1.634 inches for .308 Winchester chambers. The gage operates on a simple principle: if a round chambers using the No Go gage, the chamber is too long and poses a risk of excessive headspace. Used in conjunction with a Go gage, this tool provides the two-point verification system recommended by SAAMI standards for professional-grade chamber inspection.

This gage is indispensable for law enforcement armorers verifying duty weapon chamber integrity, military gunsmiths validating rifle compliance, and serious reloaders maintaining safety in their ammunition. The compact form factor and lightweight construction make it portable for field use, range inspections, or the reloading bench, ensuring that users can always verify chamber specifications before ammunition enters the firearm.
