## Description

The GO gauge is used to measure the minimum allowable, safe chamber headspace. If the bolt does not close on a GO gauge, it is considered unsafe. Must have for rechamber jobs to set the new headspace or to verify the correct headspace of a new barrel and bolt combination. These days, I see a lot more new barrel and bolt combos fail the GO gauge than anything. Failing the GO gauge indicates the headspace is too tight, which increases chamber pressure and failure to go all the way in battery. This leads to pierced and popped primers that will damage the firing pin tip and cause slam fires. It also can cause hard extraction and damage to case heads. The GO gauge should be used to test any new barrel and bolt combination or when swapping in a new or used bolt. This gauge ships only in the USA, No export or APO/FPO.

### ⭐⭐⭐⭐⭐ Good gauges
*by P***R on July 30, 2018*

What's to say? I bought the Go / No Go gauges for my AR15 build and they worked like they were supposed to. If I were to change anything about them I would have the size of the gauge engrave on it rather then printed. It's hard to see the size but the big green stripe on the go and big red stripe on the no go helps out.

### ⭐⭐⭐⭐⭐ Does the job
*by K***R on November 19, 2016*

It simply works as it is supposed to.
