FAQ:

Q: Do I need a headspace gauge for my 223?

A: The 223 has a significantly shorter throat than the 5.56. The shoulder is located in the same place on both chambering’s. The answer to your first question is “no” you don’t need headspace gauges. Even if your barrel is out of spec, there is nothing you can do to change it.

Q: Why choose Forster headspace gages?

A: Because your safety is on the line Forster Headspace Gages are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifle’s chamber. If a rifle closes on a GO gage the rifle chamber will accept any ammunition that is made within S.A.A.M.I. (industry standard) specifications.

Q: How do you check for excessive headspace on a gun?

A: To determine if there is excessive headspace, the chamber should then be checked with a FIELD gage. The NO-GO gage is a valuable tool for gunsmiths’ reaming new chambers, in order to ensure tight and accurate headspace. 3. FIELD: Corresponds to the longest safe headspace.

Q: What is headspace on a gun?

A: According to the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), which sets product standards for firearms and ammunition, headspace is “the distance from the face of the closed breech of a firearm to the surface in the chamber on which the cartridge case seats.”
