My gauge arrived today. It's 0.036" Both of our 15-22's measured 0.042"/0.043" so we're safe.

M&P 15-22 Safety alert from S&W

Is there a list of the rifles that could be affected then
I was under the impression it was a general alert for all rifles before a certain date, rather than a specific batch.

It is, all rifles before Feb 2019. There is a tool online where you can input your serial number if you are unsure.

helps if you read all the way to the bottom of the page doesn't it?

P.S. Mine's one of them with a DFCxxxx number

I just received my S&W go/no go gauge and it measures .036 also. I haven't had a chance yet to check my 2014 HCE, I think I'll use my caliper and measure. Hopefully mine is in the .038 - .039 range. If there is a chamfer at the chamber rim it adds to the clearance of the bolt. The SAAMI spec for a 22LR rim that I read is .043 -.007, which is .036 - .043. I don't think I'd want mine on the super loose side of the spec, I keep my 15-22 clean.

Received my gauge in the mail this morning. Using a Starrett micrometer, it measures 0.0359. I'll check my bolt later today. Oh, no free decal in the envelope. I guess you had to really be one of the first ten to get anything free. OK I just checked mine and the gauge is barely below the bolt face. I'm within spec (well, the rifle is anyway; I'm not sure about me).

I requested mine right after I shared the link on here... still haven't received it yet.

Still no sign of the gauge I ordered from the S&W International page. 
Maybe they've sent batches to their overseas agents and are relying on them for worldwide distribution.
Anyway, as the general consensus is that the magic number is 0.036" for the gauge (many thanks to all you guys for sharing BTW. It's greatly appreciated), and my bolt recess measures in at slightly more than 0.038" (post #73), I'm going to work on the assumption that mine's OK…… tight, but OK.
That is unless any one of you wise folk can think of a good reason for me not to.
FWIW, using a digital vernier caliper, I've just randomly measured the rim thickness of a load of CCI Mini-Mag (the rifle's regular diet) and the vast majority come out at 0.0395".
I've also got some of the new Eley Semi-Auto ammo (three types named Force, Contact & Action Plus) that I tried before this all blew up (no pun intended
) and rim thicknesses vary between 0.0375" & 0.0390".
Before anyone asks though, I'm not going to be buying anymore of the stuff. The Force & the Contact are more expensive than CCI, they're all dirtier than CCI and the groups are no better. Bear in mind that this is what I found from my rifle. It could produce different results in someone else's.
I think I'll just keep a close eye on the rim thickness of any new stuff I try and like a good citizen, make sure I'm pointing the noisy end downrange whenever there's a magazine fitted.

Unexpectedly received gauge today (ordered 9 March). Gauge measured .036". About as flush as can be. I must have measured the depth wrong days ago. My recess could possibly be between .036 / .037. I'm calling flush with both a high - power magnifier and dragging a fingernail.
No sticker and gluey **** (scotch tape stickum) on one side of gauge. Alcohol barely dented it. Acetone is next. OCD don't you know.

Ordered mine on the 8th in the evening. Showed up in the mail today. Based on past measurement comments and my own measurements, I'm expecting it to be good. If not, I'll post what I find.

Good eye. My BCT was covered with sticky stuff. Brake cleaner made short work. At first, I felt disenfranchised.

Mine just arrived. My trusty Harbor Freight caliper measured it at 0.0365. The same caliper said the depth of the recess was 0.039 so I am good to go.

Ordered mine on 3/9 and received today as well. All 6 of my bolts were flush or slightly below. (all are good to go)
One of my bolts has 140k+ fired on it, (bought in 2010) and the bolt face is battered a bit and it below flush. Tuff little buggers these 15-22's are.

Got mine yesterday, time to dig the 15-22 out of the safe.

I would like to hear the details on all the ones that fail, like what depth are they at ? as well as the serial prefix and date of manufacture. Seems Smith doesn't know what got out when ?

Agreed, but I have a suspicion the number that fail will be statistically low. This is a more of a CYA move by S&W.

As of 3-23-19 I have not received the return label to send my bolt back to S&W. Not even an email about it. I imagine S&W is overwhelmed with this recall.
Inserting a 22lr round onto my bolt it sure looks like my bolt will need to be replaced.

Received my gauge in the mail today, flush on the bolt in question, a little below on the older one. I'm happy.

Guess it was a Lucky S&W mail week! My test gauge arrived yesterday and both of my 15-22s passed with flying colors. I knew they would from previous measurement with my tools. Doesn't hurt to have an extra eye��
Wasn't real happy with what appeared to be a flush fit. I had cleaned the face well w/ a pointed q-tip and brake cleaner. Looked spic and span. Looked again moments ago and saw carbon up in the curved area and a smidge on extractor. Took a brass brush to it and canned air. With the naked eye it appears below the surface now; perhaps a thousandth or so. A bit surprising but I'm a happy camper now.

I know what you mean. I was quite surprised at how much crud builds up in that radiused area. I just keep a handful of toothpicks and a bronze brush in the range bag now.
Received my gauge 3/25/19, checked it with 2 calipers, manual and digital, both at .035. Measured the bolt face with both at .040 and the gauge verified it's ok. Older rifle shot regularly, cleaned when it tells me to, usually mini mags, no problems so far. Ser. # HBZ6XXX. Good luck with it everyone.
"Radiused". That's the word I was looking for.

Talking with a guy at work today who advised me that S&W aren't shipping the checking gauges overseas.
Knowing that said 'guy' is a complete spanner who, if his stories are to be believed, can regularly hit V bulls at 1000yds more often than the GB Rifle Team, I decided to call S&W Customer service direct.
I've just got off the phone (7pm local time / 3pm US time) after talking with a very nice lady who advises me that a batch of gauge requests for overseas customers was dispatched on the 15th March with a two to three week delivery time.

I still haven't received the email confirmation and was starting to worry.
Thanks for the update.
My local RFD have been back in touch saying Sportsman gun centre said to send it back to them through him and they would deal with it. But if the guage is in the post I'd rather wait as I think mine is within spec. Sportsman will be my backup if the guage doesn't appear.
