I was unable to locate a prior discussion I saw on which gauge is the best to buy no-go type which did not require bolt dis-assembly for 5.56 bolts. Any opinions, Brownells/Midway.

Maybe one exists, but I'm not familiar with any headspace gauges that let you close on a complete bolt. I'd be interested if such a thing exists, but I think you'll be going after a gauge with a grinding wheel if you want to close a bolt with the ejector and extractor.

If you only want to buy one, it's the field reject. the go and no-go guages will depend on what your chamber actually is. But saami or nato, field reject is bad.


Arc.

The official gauge (M16 Maximum Headspace Gage, Ordnance Part Number 7799734, NSN 4933-00-070-7814) has a cut to make it usable on a complete bolt. I have not seen one for sale is quite some time. I personally just mill the commercial gauges (a project any good machinist can do for you in about a minute, I do it on a small home mill) so you don't have to disassemble the bolt.
Not that disassembling the bolt is a big project, it just irritates me. i have written to all the normal gauge suppliers saying there is a market for a real clone of the official gauge but obviously they don't think so.
