Forster Headspace Gage: The Gunsmith's Essential Tool
Proper headspace measurement is the foundation of safe, accurate rifle performance. The Forster Headspace Gage for .308 Winchester is manufactured with the precision and care that this critical task demands.
Understanding Headspace
Headspace is the distance between the breech face and the base of the cartridge when the action is fully closed. Excessive headspace creates serious safety risks:
- Unsupported brass can rupture under firing pressure
- Gas blowback can occur, creating dangerous rearward pressure
- Accuracy suffers from inconsistent chamber fit
How the GO Gage Works
If your rifle closes on this GO gage, your chamber will safely accept any ammunition manufactured to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) industry standards. This is the baseline measurement for safe operation.
Professional Standards
Most gunsmiths chamber rifles with headspace falling between the GO and NO GO dimensions—a proven safe zone. The Forster gage is manufactured to exacting standards, ensuring reliable, repeatable measurements you can trust with your safety and your rifle's performance.
For serious shooters and gunsmiths: proper headspace verification isn't optional—it's essential.
