Forster Headspace Gage FOR 22 RIMFIRE NO GO

The Forster Headspace Gage for .22 Rimfire NO GO is a precision measurement tool designed for shooters and gunsmiths who demand absolute chamber accuracy. This "NO GO" gage establishes the maximum allowable headspace limit for .22 rimfire firearms, serving as a critical quality-control standard during reloading, rifle maintenance, and barrel validation.

Constructed from hardened steel with precision machine finishing, this compact tool resists wear and maintains accuracy across thousands of inspections—critical for high-volume training facilities and duty armorers who perform frequent chamber diagnostics. The NO GO variant is sized to reject any chamber that exceeds maximum safe headspace, working in tandem with a GO gage to bracket acceptable tolerances.

This gage is essential for .22 rimfire firearms including training rifles, match weapons, and duty arms where chamber integrity directly affects shooter safety and performance. Law enforcement agencies and military units rely on headspace gages to validate rifle conditioning after barrel replacement or extended service life.
