no, but I am pretty sure this is a forum member that I trust.

Pretty sure it is Dave, and he knows what he is talking about, I have been tempted to bid on it, although I've never seen one of these.

I think it must have to do with reloading or gunsmithing. The thing does look a little like a 9mm brass casing. Below is some text I found on the topic.

"These Go /No-go gauges are designed to verify that chamber headspace is within tolerance from the base to the shoulder. It is best to remove the ejector on most rifles so that you can "feel" these gauges as they are chambered. The Go gauge can also be a handy tool that can help you check the depth setting on your NK or FL resizing die"

This is my interpretation of what I have abosorbed on the topic over the years if I have misintepreted any of the following someone plez correct me.

GONOGO gauges measure the amount of "headspace" between the cartridge and the face of the bolt when the cartridge is inserted into the chamber. You usually have two cartidges one for go and one for no go.

The chamber wears away over live fire usage with super heated gases being generated with every round, the same for the opposite end called muzzlewear, they have gauges for that too.

As the chamber erodes and enlarges the cartridge will seat further up into the chamber creating larger headspace clearance. When the round is fired the casing will have a bigger space to expand or kickback into the face of the bolt damaging the bolt and possibly the unfortunate user.

The markings on the gonogo gauges will tell ya whether its safe to operate. Too much headspace and the cartridge will damage the bolt and or operator when fired. Too little head space is not good either.

The long and short of it is it will tell ya if you have excessive chamber wear and if it is unsafe to shoot.

Quit frankly if you are looking at any kinda shooter that you want to use where the barrel is not in yer opinion "minty" or in good condition or any of the other hi end quality barrel buzz word terms used for barrel description you should be running it through a gonogo gauge test as part of yer 3 day inspection in my humble opinion.

Here is a great article that gets down to the nuts n bolts of it.
