The Forster 6.5 PRC GO Headspace Gage (brand part no. HG65PRCG) gives gunsmiths and handloaders a precise way to check that a 6.5 PRC rifle chamber is cut to a safe headspace before firing. Headspace is the distance between the face of the breech and the base of a chambered cartridge, and excessive headspace can let unsupported brass rupture under pressure, sending gas rearward toward the shooter. Forster machines its Headspace Gages to exacting tolerances so the test result can be trusted: if the rifle closes on this GO gage, the chamber will accept any 6.5 PRC ammunition made to SAAMI specifications.

Key Specifications

• Chambered specifically for 6.5 PRC.
• Functions as a GO gage, confirming the chamber accepts SAAMI-spec ammunition.
• Machined to exacting tolerances for a trustworthy pass/fail result.
• Measures approximately 3 inches long.

What does a GO gage tell you? If the rifle’s bolt closes on it, the chamber will accept any ammunition made within SAAMI specifications.
