Forster Products 6.5 Prc Go Headspace Gauge Headspace Gauge Steel

The Forster Products 6.5 PRC Go headspace gauge is a precision measuring tool built for reloaders and gunsmiths who need to verify that a rifle chamber meets safe operating specifications. This is the "Go" gauge in Forster's SAAMI-compliant headspace system—it confirms that your 6.5 PRC chamber will reliably chamber and fire a cartridge. If you're setting up a new barrel, diagnosing a potential headspace issue, or evaluating a used rifle before you shoot it, this gauge gives you the confidence that your chamber is within safe limits.

Headspace directly affects safety and reliability. Too much or too little, and you're inviting misfires, case failures, or accelerated wear. A quality headspace gauge eliminates guesswork. Forster's go gauge is machined to exacting SAAMI specifications and hardened steel construction that holds its accuracy through repeated use—no creep, no drift. It's the kind of tool that pays for itself the first time it catches a problem or confirms a chamber is good to go.

The Forster headspace gauge system uses three complementary gauges (Go, No-Go, and Field) to perform a complete assessment of chamber condition. This Go gauge is your baseline: the bolt should close on it smoothly. Using it alongside the No-Go gauge (bolt should not close) gives you a clear window of whether your chamber is within safe limits or headed for trouble. For serious reloaders, gunsmiths, and shooters who demand control over their ammunition and firearms, a precision headspace gauge is non-negotiable.

Frequently Asked Questions

What's the difference between Go, No-Go, and Field gauges?

The Go gauge confirms the minimum chamber size—your bolt should close on it. The No-Go gauge checks that the chamber hasn't grown too large; your bolt should not close on this gauge. The Field gauge represents the absolute maximum safe headspace; if your bolt closes on the Field gauge, the rifle is unsafe to shoot. Together, all three give you a complete picture of chamber condition.

When should I use a headspace gauge?

Use it when you're chambering a new barrel, troubleshooting ignition or extraction problems, or evaluating a used rifle before purchase. Regular reloaders also use headspace gauges to monitor whether repeated firing has stretched a chamber beyond safe limits.

Do I need all three gauges, or just the Go gauge?

The Go gauge alone tells you if your chamber will function safely. For a comprehensive assessment that confirms your chamber hasn't exceeded maximum headspace, you'll want the No-Go gauge as well. The Field gauge is typically used only when you suspect serious headspace problems.
