Forster .223 Remington GO Headspace Gage

The Forster .223 Remington GO Headspace Gage (brand part no. HG0223G) gives handloaders and gunsmiths a precise way to verify chamber headspace before ammunition is ever fired. Forster machines each gage to a tight 1.464 in reference length, matching the minimum SAAMI chamber dimension for the .223 Remington cartridge. If a bolt closes freely on this GO gage, the chamber will safely accept ammunition loaded to standard SAAMI specifications. It is a companion tool to Forster’s NO GO gage and belongs in any serious reloader’s bench kit or a gunsmith’s chamber-checking set.

Key Specifications

• Machined to a precise 1.464 in reference length, matching the SAAMI-minimum .223 Remington chamber dimension.
• Cut specifically for the .223 Remington chamber, so results are caliber-correct rather than a generic estimate.
• Functions as a GO gage, confirming the chamber will accept ammunition built to standard specifications.
• Sold as a single gage for use alongside a matching NO GO gage when fully bracketing chamber headspace.

Frequently Asked Questions

What does it mean if my bolt closes on this GO gage? It means the chamber accepts the minimum SAAMI dimension, so standard factory or handloaded .223 Remington ammunition should chamber and fire safely.

Do I need the NO GO gage too? Most gunsmiths use both a GO and a NO GO gage together to confirm the chamber falls within an acceptable headspace range rather than relying on just one reading.
