Forster Headspace Gage Rimmed & Belted 7.62x54 Russian NO GO
Forster NO GO headspace gage for 7.62x54 Russian rimmed and belted cartridges. Precision-manufactured to exacting standards for accurate chamber testing and safe firearm operation.
Understanding Headspace
Headspace is the critical distance between the breech face and the cartridge base when the action is fully closed. Excessive headspace creates a dangerous condition that can compromise both safety and accuracy.
Why Headspace Matters
When unsupported brass is fired in a rifle with excessive headspace, the case can rupture catastrophically. This allows high-pressure gas to escape rearward—a hazard comparable to rocket exhaust. Proper headspace verification is essential for safe shooting.
Forster Quality Standards
Forster Headspace Gages are manufactured with meticulous attention to detail and exacting tolerances. Each gage is engineered to provide accurate, reliable chamber testing.
How to Use This NO GO Gage
GO Gage: If your rifle closes on a GO gage, the chamber accepts any ammunition manufactured to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications.
NO GO Gage: If your rifle closes on this NO GO gage, your chamber may have excessive headspace and requires professional evaluation.
FIELD Gage: If your rifle closes on a FIELD gage, the chamber is dangerously close to or exceeds SAAMI maximum specifications.
Professional Standard
Most gunsmiths chamber rifles with headspace between GO and NO GO dimensions. Use this gage as part of a complete headspace verification set to ensure your rifle is safe and accurate.
