M&P 15-22 goes boom...not good

[myeye22]

I can't believe after all these months, this is still possible on this rifle and hasn't been fixed. The OPs experience is yet another example of why the 15-22 should be recalled.

Along with how many others? It's a rimfire after all. OOB's can happen - even with the best ammo and cleaning, which is why lefty firing these things ain't exactly a good idea either. If it's any consolation to the OP, it could have been worse. No way I'll put my face on the same side as the port - rimfire or not.

If you notice, he said it was a DTU number, so it isn't a new rifle. It just sat on a shelf somewhere.

All us left handed people are just asking for trouble then?

I guess I should adapt to your superior right handed technique that I've been shunning for decades

That's exactly what recalls are for, to notify consumers and fix ALL of them, including old stock.

The fact that it's a rimfire doesn't change anything. Any firearm which can fire OOB is unsafe. So it's ok for the OP's thumb to get scorched and cut? What's next? It's ok for a kid to lose an eye from one of these things just because they are a lefty or because it's just a rimfire?

Concerning left handed shooting. I'm left handed and have shot left handed all of my life. A couple of years ago I had an ICD implanted and the surgeon said no more left handed rifle shooting. (It's in my left upper chest. So, I figured that was that.) Then the 15-22 came out and I had to have one. I bought my 15-22 and learned to shoot it right handed. Seemed very awkward at first but soon became accustomed to it. I didn't really think .22lr recoil would be a problem but I'm inclined to listen to my cardiologist in matters of the heart

Yes.

Lefty is good for playing hockey. Sticking your face in the ejection port, not so good....

Lefty

I shoot left handed because I'm very left eye dominant, not because I'm left handed. I can't sight well shooting righty and it feels very awkward. I may be taking extra risk but I also think tacticool is right. And I don't hold my right hand anywhere near the port.

I just tried shooting left handed, without any ammo, with my hand on the magwell like you said you did. If your thumb creeped aver the ejection port, it could have prevented the bolt from fully closing. But it is far enough forward for the trigger to release the hammer. BOOM, you have an out of battery detonation. Just like Phils pic, then the next bullet crushed the rest of the cartridge into the breech face and got jammed. Just a theory. Hope your thumb is better. Powder burns are very painful.

Another 'lefty' here, just purchased my 15-22 and waiting for the 10 day period to end. Mine is a DUU serial number, which I believe is newer and should have the upgraded springs and components, correct? With the rifle broken down, I remember seeing blue springs around the hammer area. Thanks in advance for confirmation one way or the other.

[grimreaper21]

yes that is correct, even some of the earlier serials had the same upgrades. DU*?

 

[john16443]

Good, at least I can fell better knowing that I didn't get an older 15-22 that hasn't been reworked. Maybe I'll still have to use a face shield when I take it out

 

[jsimmons]

I have a DUA rifle, and it has the blue spring upgrade and the newer magazine.

 

[JMusic]

Mines did a OOB several times, from me dicking with the trigger. You can tell by measuring the empty case.

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...

[bradystrib]

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.

 

[BeginingOfTheEnd]

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.

 

[Skunkhome]

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.

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.

 

[Vision Remodeling]

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.
