The Forster .223 Remington NO GO Headspace Gage (brand part no. HG0223N) is the other half of a proper chamber headspace check, machined to a 1.467 in reference length. If a bolt closes on this gage, the chamber is cut longer than the accepted working range and may have excessive headspace, a condition that can hurt accuracy and, in extreme cases, brass reliability. Forster builds these gages to exacting tolerances specifically for gunsmiths and serious handloaders who want a real answer instead of a guess before ammunition is chambered.

Frequently Asked Questions

What does it mean if my bolt closes on this NO GO gage? It indicates the chamber may have excessive headspace and should be inspected by a gunsmith before the rifle is fired further.

Is this the same as a FIELD gage? No. A FIELD gage represents the maximum allowable chamber length; a NO GO gage sits between the GO and FIELD dimensions and is the standard gunsmithing reference for a properly cut chamber.
