I used this to check Colt SAA 1st Gen
1st Gen Colt SAA checked out OK with this gauge.Works as advertised.Had to remove cylinder to get the gauge out, since it would not rotate into recoil plate.

For peace of mind
When changing barrels on an AR-10, I realized that I had no way to check headspace.before firing it.A cartridge will do for a Go gauge, but a No-Go gauge is safer than a field gauge to start with.When used in an action like a Mauser or Model 70 there is nothing to do before trying to chamber it, but with an AR you should remove extractor and ejector beforehand.

I purchase this Gauge after trying to locate a gunsmith near where I lived and worked to check the head space on my AR build.It was cheaper than a 2-3 hour drive and it work as it was designed.

Good Gauge
Good Gauge, Good Value.The identification on the gauge is not easily readable, but it should be kept in its well labeled case like any precision gauge.
