OK I guess

Gave it 4 stars because of my faults in not knowing how to use this. Not the products fault. Will check with Brownell and see if they have a video on this particular go guage.

Would you recommend this? Yes, I would recommend to a friend

Good product, no extractor cutout.

I have to give it a good review because it's my fault. The extractor on my mosin nagant 91/30 absolutely won't budge. The go works fine but the no go obviously won't seat correctly without the removal of the extractor. Both (go and no go) look like fine tools but I can't rate them so much as I can say you DON'T have to remove the firing pin you DO have to remove the extractor so make sure you can do that before ordering them.

Head Spacers

These spacers are two expensive for what you get. I know they can be cheaper. They do work but very expensive.

Finish grind is rougher than I would expect

Sizes measure ok, I’m just concerned about the finish scrsatching a freshly reamed chamber. I’ll likley do a light polish to smooth the sharp spots off so it slides into my test chamber cut with a new reamer.

Inaccurate

Found the clymer 308 winchester family GO gauge to be inaccurate it measures at 1.6285 and states it is 1.630. This is only off by 0.0015 but the point of this gauge is to be precise. I purchased a different brand and it measures at exacly 1.630 so went with that one instead and will return this one. Other than that it looks good, is easy to use and read, but that really doesn’t matter much if it isn’t accurate.

Do Not Buy

Pros - none Cons- does not work Best uses- fishing weight The body on this gauge is 0.217", the 22 Hornet measures 0.2945" that makes for 0.0775" of slop. Can not place gauge in the breech and close the bolt because the gauge drops and hits the rim of the bolt. Tom, Sun Mountain Gunsmithing LLC

Poor QC

Purchased the set individually and both were of in diameter by a few thousands. Had to pay one smith for removing the barrel and then pay another for installing the new barrel since he actually had another set of G/NG gauges. Do not buy. Will be writing the same review for the other gauge as well.

Hard to read identification on tool

Identification should be engraved on tool. Ink is too light. I bought a go gauge and a no-go gauge. The ink on both tools is hard to read. Neither came with any instructions

Gauge Identification

Gauge identification is not the best. Barely readable. Clymer should engrave the identification what the tool is into the body or head. These are my first and only set of headspace gauges. So I will know that they are 5.56. But to make sure not to confuse them. I will get some red and green paint and paint the ring in front of the head. Green for go gauge, Red for no-go gauge. I did not mic them yet. The identification ink is the only problem I've seen.
