Forster Headspace Gage GO 7.62x39
Proper headspace measurement is fundamental to safe rifle operation and accuracy. The distance between the breech face and the cartridge base—known as headspace—directly impacts both safety and performance. Excessive headspace can lead to dangerous brass rupture and loss of accuracy.
Why Headspace Matters
When a rifle closes on a GO gage, the chamber will safely accept any ammunition manufactured within SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications. This is your baseline for safe operation.
Forster manufactures these critical tools with meticulous attention to detail and exacting standards. Each gage is precision-engineered to provide reliable, repeatable measurements you can trust.
How to Use
- GO Gage: If the rifle closes on this gage, the chamber is within safe SAAMI limits
- NOGO Gage (sold separately): If the rifle closes on this gage, headspace may be excessive
- FIELD Gage (sold separately): If the rifle closes on this gage, the chamber exceeds safe SAAMI maximums
Most gunsmiths chamber rifles with headspace falling between GO and NOGO dimensions—the optimal safety zone.
