Forster 6.5 PRC Go Headspace Gage

The Forster 6.5 PRC Go Headspace Gage is the precision measurement tool every gunsmith and reloader depends on to verify rifle chamber specifications with absolute accuracy. Proper headspace measurement is foundational to safe ammunition handloading and firearm assembly—excessive headspace creates dangerous pressure anomalies and degrades accuracy, while insufficient headspace can cause feeding failures. This go gage establishes the maximum acceptable chamber length for the 6.5 Precision Rifle Cartridge, allowing operators to confirm whether a rifle action meets specification before firing.

Manufactured by Forster Products, a trusted name in precision reloading equipment and gunsmithing tools, the 6.5 PRC headspace gage provides dimensional verification that no feeler gauge or improvised method can replicate. The go gage measures 3.75 inches in overall length and weighs just 0.12 pounds, making it portable for mobile armoring operations or permanent shop installation. When used in conjunction with a no-go gage, the go/no-go system ensures your chamber falls within SAAMI specification limits—critical for long-range rifle builds where even 0.002 inches of deviation can impact bullet jump and terminal ballistics.

This tool is essential for precision rifle gunsmiths, serious reloaders, military armorers, and anyone building or maintaining a custom 6.5 PRC rifle. Whether you're assembling a precision long-range platform, diagnosing accuracy issues on an existing rifle, or verifying a custom barrel installation, headspace measurement is non-negotiable. The 6.5 PRC has become a standard in precision rifle competitions and tactical applications, making this Forster gage a permanent addition to any professional shop's equipment inventory.
