A complete recall of the M&P15-22 can't and won't happen unless and until there's a solution for the problem.
OOB firing is a function of the stock AR15 trigger group which can release the hammer before the bolt is fully closed (I think research here indicates at least 1/8" open); the angle of the aft face of the 15-22 bolt which allows the hammer to strike the firing pin before the bolt is closed; and anything that retards the cartridge from entering the chamber. You can only control the last factor and that includes a dirty chamber, dirty ammo, etc.
I've had one (1) with this rifle and she made the trip to S&W. Not had an OOB in nearly 2,000 rounds since then. I agressively polished the chamber and I don't pick up ammo off the ground and reload it (external lubrication on .22LR will pick up lots of dirt).
OOB happens on literally all the self-loading .22LR firearms I've owned. Is normally quite harmless, although startling when it happens. The 15-22 usually sheds its extractor when this happens.

Back from S&W
I received it back today, and for damn sure I'm not impressed. I specifically asked for the jammed casing to be returned, and it wasn't. I also asked that they tell me the cause of the problem, and they didn't.
I got a form saying it had been examined and adjusted, then says repaired & Updated to latest spec. Also says on the bottom to call if I have any questions, they better be expecting one. They also replaced my magazine with the new model. I had really hoped for better from them. I still have no idea if it was the ammo or the rifle. It wasn't like I was out to sue anyone, I just wanted to know what happened, like I said, I'm not impressed with them...

yeah that's crazy. i don't think they want you to ship ammo new or spent in the same case as the gun. I think i remember reading that somewhere. Might be why they didnt send it back. On a side note....be happy they fixed it.

Were the springs replaced with blue colored one's?
Yes, they were
dont really think anyone has gotten any answers in the whole time these guns have been out. We had retailers here trying to get answers as to why their guns were being returned and S&W wouldnt even tell them anything.
Find someone that has a bolt action rifle and give them to him/ her. Most .22 autos are partial to one ammo over another mine does not like the Winchester ammo either but digests the federal flawlessly. But I can take those Winchester rounds and shoot them all day in my CZ bolt action with great accuracy. As a matter of fact those same Winchester rounds shoot well in my Beretta Puma.I recently bought a box of that ammo from Wally World. I fired appox half the box and had 8 FTF/FTE. I dont think I will be finishing them....
How are live rounds of possibly defective ammo properly disposed of?
Amen, brother. That is another reason why I like the forum.

I had it happen with Whinchester ammo myself, did no damage to me or the gun but was a wake up. Have had about 1500 rounds of federal bulk go through it with no problems since then.

It is generally not recommended to grip the gun by the magazine when firing. You can shift the position of the mag causing feed problems

same thing happened to me as OP
was out firing this past weekend and had the same thing happen, nobody was injured at all, and i am new to this rifle but have fired many M16A2's and M4's while in the Army, think it was OOB firing, casing stuck in chamber, so i dropped mag and broke rifle down to pull bolt out and then get casing out, however when i pulled the bolt out i had a small spring and pin fall onto the table i was working on, called S&W Monday still awaiting shipping label to send rifle in. i have no idea where the pin or bolt came out of on the bolt or some where in the upper reciever but think it was from bolt, also no idea if something else came off that i didn't see or find if it hit the table and rolled or fell off into the grass. guess we will see what S&W tells me. Just bought the rifle in Aug 12', seriel number starts with a DTZ, if that means anything to you all. if anyone on here has any idea please let me know.

yes the take down pins are still attached to lwer, i did take the pistol grip off in preperation to send it back in and put the stock pistol grip back on it, both the springs were still in there.

yeh thats what i figured,, i am just hoping they figure out what happened to it and fix it, that would be more important to me, i don't get a chance to shoot very often anyways becuase of work schedule. did you return yours for the same reason? hope you get it back soon.

Thanks,
Paul

I also had an OOB. S&W repaired, Nooo problems
I purchased my second M&P 15-22 on 22 Dec 2012. Was shooting Winchester 36 grain when the OOB ocurred which blew the extractor out.
Sent the rifle back to S&W and they fixed it without question. 
FYI. Photos below of the cartridge and the bolt (extractorless).

Mike,
Thanks for the reminder, I have seen this ammo correlate to several other OOB detonations... this is going to be one ammo I am going to definitely stay away from using.!!!!
Glad to hear you got your rifle back.!!!

Yeah, I'm a bit hesitant to finish the Winchester ammo
What's really interesting about this whole OOB issue are the discussion points that the occurances are common (although not frequent)
I am a bit preplexed when I look at all the possible factors. Still, I am very hesitant to use/finish the same brick of Winchester ammo. That brick will more than likely be used up with my pistol, or I'll only do very controlled, slow fire with the 15-22.
Smith and Wesson did me good however. They got me all fixed up. Kudos to them!

- to .22 Semi's,
- ensuring bolt and chamber faces and chamber are clean
- to the FCG-Bolt closure/action of the M&P 15-22
- related to poor quality/dirty ammo
- a combination of all the above

I got my 15-22 yesterday evening, no chance to shoot yet, but browsing through the manual saw a list of ammo they do not recommend...don't specifically remember what was on it, and it's not in front of me but I'm wondering if some of the ammo mentioned in this thread is on that list?..

FWIW, that list dates from the introduction of the 15-22 and may well be outdated and no longer reflective of today's ammo quality. The changes over the past few months in Remington's products is proof of that.
IMHO, today that list, especially the "not recommended" list is useless. Try any ammo and see how it performs in YOUR rifle.

Send me the ammo; I'll shoot it for you.

Good Point.
This is a copy from the manual. But I agree, try and see what works. I was shooting Winchester HV 36g, which isn't on the "not recommended" list. But Winchester Wildcats are.
You make a good point. I'm a lot more cautious though, and mindful.
