Forster 6.5 Grendel GO Headspace Gage
Precision GO headspace gage for 6.5 Grendel chambers. Essential gunsmithing tool for verifying safe chamber dimensions and ensuring ammunition compatibility with SAAMI specifications.
Understanding Headspace
Headspace is the critical distance between the breech face and the base of the cartridge when your rifle's action is closed. Proper headspace is fundamental to safe, accurate shooting. Excessive headspace creates dangerous conditions—unsupported brass can rupture under pressure, allowing gas to escape rearward with potentially catastrophic results.

Why It Matters
Whether you're building a custom rifle, having a chamber reamed, or verifying a used firearm, proper headspace testing is non-negotiable. This GO gage gives you the definitive answer: is your chamber within safe, functional limits? Your safety depends on getting this right.
