Forster 6.5 PRC Field Headspace Gage

The Forster 6.5 PRC Field Headspace Gage is the gunsmith's standard tool for accurately measuring rifle chamber headspace, the critical distance between the breech face and cartridge base when the action closes. Manufactured by Forster Products, this field headspace gage eliminates guesswork and prevents the dangerous consequences of excessive headspace—including brass rupture, rearward gas blowback, and accuracy degradation.

Excessive headspace creates a safety hazard by allowing unsupported brass to rupture under firing pressure, potentially directing hot gases and metal fragments toward the shooter. Beyond safety, even slight headspace deviation degrades precision and shortens brass life. The 6.5 PRC field headspace gage provides the go-no-go measurement standard that competitive shooters, precision rifle builders, and ammunition developers rely on to verify chamber specifications. Compact enough for range use and durable enough for bench or gunsmithing shop work, this precision instrument delivers repeatable results across repeated measurements.

This tool is essential for anyone handloading 6.5 PRC ammunition, building custom rifles in that cartridge, or diagnosing chamber issues in existing firearms. Reloaders who demand consistency, gunsmiths fitting barrels or actions, and shooters troubleshooting accuracy problems all benefit from direct headspace verification rather than relying on indirect chamber checks. The 6.5 PRC cartridge's popularity in long-range and precision rifle applications means a dedicated field headspace gage for this caliber belongs in every serious reloader's and gunsmith's kit.
