Forster 6.5 Grendel No Go Headspace Gage
Understanding Headspace
Headspace is the critical distance between the breech face and the base of the cartridge when the action is fully closed. Excessive headspace creates a dangerous condition that can rupture unsupported brass, allowing high-pressure gases to escape rearward with potentially catastrophic results. Proper headspace verification is therefore non-negotiable for both safety and accuracy.
Why This Gage Matters
Every serious gunsmith relies on headspace gages as the most dependable method for testing rifle chamber dimensions. Forster manufactures these precision instruments with exacting standards and meticulous care to ensure accurate, repeatable results you can trust with your safety.
How to Use This No Go Gage
- GO Gage: If your rifle closes on a GO gage, the chamber accepts any SAAMI-specification ammunition safely.
- NO GO Gage (this tool): If your rifle closes on a No Go gage, the chamber may have excessive headspace and requires immediate attention.
- Field Gage: If your rifle closes on a Field gage, the chamber is dangerously close to or exceeds SAAMI maximum specifications.
Most professional gunsmiths chamber rifles with headspace falling between GO and No Go dimensions—the safe zone for reliable performance.
The Forster Standard
Manufactured to precision tolerances that demand nothing less than accuracy, this No Go gage is an essential tool for anyone responsible for rifle safety and performance.
