Forster Headspace Gage FOR 350 LEGEND NO GO

The Forster Headspace Gage FOR 350 LEGEND NO GO is the precision chamber measurement tool every serious gunsmith and reloader needs for verifying rifle chamber dimensions. Headspace—the distance between the breech face and the cartridge base when the action is closed—is critical to both safety and accuracy. A NO GO gage confirms that headspace falls within safe limits, preventing the dangerous condition of excessive headspace that can cause brass rupture and catastrophic gas venting.

This specialized 350 Legend headspace gage is calibrated to the NO GO specification, meaning it should NOT enter the chamber of a properly dimensioned rifle. When used in conjunction with a GO gage, it establishes the acceptable tolerance window for chamber length, protecting both shooter safety and ammunition performance. The compact design (3.5 x 0.75 x 3.5 inches) fits easily in a gunsmith's toolkit, and the minimal weight (0.08 lbs) makes it portable for range work or shop use. Proper headspace measurement prevents unsupported brass failures that would otherwise compromise accuracy and create liability.

Gunsmiths, reloaders, and firearms manufacturers working with 350 Legend chambers rely on precision gages to maintain quality control. Whether you're building a custom rifle, inspecting a used firearm, or testing chamber wear after extended use, this NO GO gage provides the objective measurement needed to verify chamber dimensions meet SAAMI specifications. It's an essential tool for anyone responsible for chamber integrity and shooter safety.

350 Legend headspace gages are standard equipment in professional gunsmithing work.
