Tavor no-go gauge...

[Nic3500]

Greetings, so I tested my Tavor with a no-go gauge, it closes like it's regular ammo, or like it is a go gauge...

What now? I am SOL? How can that be adjusted (if at all?)

Or did I misunderstand the method for checking head space? Drop in the no-go gauge and try to operate. If it closes properly on a no-go gauge, then the head space is to large. Is that it?

Thanks for any ideas, Nic.

If it closes on a no-go, then the headspace is above max. Take it to a gunsmith.

What gauge are they ? .223 Remington or 5.56 NATO. I'm sure the tavor can handle both since the manual said so.

Why are you even checking it?

If you change your barrel you're supposed to check it. That's why IWI us does the installations themselves. I've been meaning to check mine actually.

It's a military rifle. Loose tolerances are designed into them for functionality under adverse conditions. Is it causing the cases to split or otherwise be deformed? If not, I wouldn't worry about it. I checked our range gun last week and same thing, closed on no-go. It has probably 10,000+ rounds without issue.

It may be just the fact that many military rifles have generous headspace. Since no concern is given to reloading cases, and a military rifle must function in all matter of adverse conditions of wet, sand, mud and dirty, banged around cartridges, if a military rifle had a tight, target headspace chamber it would be too easy for it to get jammed up.
If you have access to a "field" gauge, this is the final allowable size for chamber dimension.

The gauge I have is a 223. I took the rifle apart, the bolt locks well into the barrel lugs. But it will lock with the no-go gauge in the chamber.
I had a look at my brass, no deformation, no trouble. I have shot about 2000 rounds with it, never an issue.
Your comments about it being a military rifle make sense...

Your gauge is for commercially marked .223 Remington rifles. As previously mentioned military standards are looser.
