Determines Safe Chamber Length

Verifies chamber length so you know your rifle is absolutely safe to fire. The Go gauge is used to measure the minimum allowable, safe chamber headspace. If the bolt does not close on a Go gauge, the rifle is considered unsafe to shoot. Slightly longer, the Field gauge is used to measure the absolute maximum allowable, safe chamber headspace. If the bolt closes on a No-Go gauge, the Field gauge is used for an additional check. If the bolt then closes on the Field gauge, the rifle is considered unsafe to shoot, you’ll have to have the barrel set back and rechambered. Includes a durable, plastic storage case.
