Precision headspace gage for .308 Winchester rifles. Essential gunsmithing tool for accurate chamber measurement and safety verification. Forster manufacturing quality.
Critical Chamber Measurement Tool
Proper headspace measurement is fundamental to safe rifle operation and accuracy. The Forster .308 Winchester No Go Headspace Gage is the standard tool gunsmiths rely on to verify chamber dimensions and protect shooter safety.
How Headspace Affects Your Rifle
Headspace is the distance between the breech face and the base of the cartridge when the action is closed. Excessive headspace creates serious problems:
- Unsupported brass can rupture under firing pressure
- Gas escapes rearward, creating dangerous conditions
- Accuracy suffers from inconsistent cartridge seating
- Premature case failure becomes likely
Understanding the Three-Gage System
Forster headspace gages work in conjunction with GO and FIELD gages to establish safe chamber dimensions:
- GO Gage: If your rifle closes on this gage, the chamber accepts all S.A.A.M.I. standard ammunition safely
- NO GO Gage: If your rifle closes on this gage, headspace may be excessive and requires attention
- FIELD Gage: If your rifle closes on this gage, the chamber exceeds safe S.A.A.M.I. specifications and is dangerous
Most gunsmiths chamber rifles with headspace falling between GO and NO GO dimensions—the safe zone for reliable performance.
