S&W M&P 15-22 blows up???

cosmose · 12-07-2012, 16:28

so I'm out shooting some cci quiets and decide to shoot a few aguila sub-sonic rounds, first few rounds shoot fine then it's like a mini explosion by my head, I'm guessing it fired out of battery??? casing looks real funky, it blowed out a spring and my extractor not sure what else is messed up. thankfully it did not hurt me or my brother. it was LOUD my ears are still ringing.

do you guys have any idea on what happened??
and how do i go about fixing it? I figure on calling or emailing smith and wesson tomorrow

man that sucks, i have the same gun, and its been flawless (knock on wood). Smith and Wesson should take care of that, no prob.

I just looked at mine, and your missing the extractor. That might be the broken part.

it's a big bummer just sent an order for new upgrades a few days ago

matter of fact i was testing my new forend grip when it blowed

Keep that casing, all parts and the rest of the ammo and packaging.
Contact S&W.....they will take care of you

How does the barrel look is there anything that could have obstructed it?

The barrel looks fine, I had already shot 10-15 rounds of quiet before the sub-sonics so no obstructions.

GlockPride · 12-07-2012, 20:52

I thought the super quiets and other types should not be shot out of a rifle?

Since some of the projectiles are powered by priming compound only, they might be subject to not leaving the barrel every time.

collim1 · 12-07-2012, 20:53

Wow, I really wouldn't have thought that little .22 firing out of battery would wipe out the extractor.

Save the casing and the pics to turn over to S&W. They should take care of it.

Is there not a safety measure to prevent firing out of battery in that gun?

I was shooting the CCI quiet 22lr 40gr @ 710 fps

I don't know I thought all guns had them...I'm still not sure what really happened maybe something broke

WoodenPlank · 12-07-2012, 20:58

Yep, OOB discharge. I had it happen once with a .22 conversion kit in an AR-15. It's definitely not a pleasant experience.

Berto · 12-07-2012, 22:16

In rimfires, it's not unheard of for the extractor to set off the primer while chambering.
Any instance where it 'hit' the rim due to being fouled either under the extractor or at the breech face, a jammed ext spring (holding it down) could be enough to set off the primer.

Bill Keith · 12-07-2012, 22:54

The Aquila rounds do not have the power necessary to make a semi-auto work properly. I'm surprised your slide was able to function at all to attempt to load one of the powderless bullets.

**Cole125** · 12-07-2012, 22:55

Thats a POS anyways...

Get yourself a CMMG .22 lr AR upper, mines never jammed and is more accurate than any of my 10/22s.

mjkeat · 12-07-2012, 23:40

Yeah, and it doesn't have a bolt hold open which renders it useless as it doesn't keep with the correct manual of arms like the M&P15-22 does. I would trade my CMMG dedicated upper for a M&P15-22 anytime.

Jammed... All of a sudden I'm hungry for a PB&J.

TTM65 · 12-08-2012, 04:05

I would bet that you had a blockage in your barrel.

I am thinking similar to Berto........only I suspect the extractor failed first and caused the OOB.

ooc

The good news is that S&W customer service is usually very good with shipping and repair gets it fixed quickly.

Good luck. Mine has probably 1500-2000 rounds without issue.

Check out page 10 of your owners manaul:

Through our testing, Smith & Wesson has also found that there
are several brands and types of .22LR ammunition that do not
perform consistently or reliably. Consequently, Smith & Wesson
DOES NOT RECOMMEND that the following brands or types of
.22LR ammunition be used in your M&P15-22 rifle:
• Remington Golden Bullet • Remington Thunderbolt
• Remington Target 22 • Winchester Wildcat
• Any and all sub-sonic brands and types

They specifically tell you not to use sub-sonic ammo. bet they will fix it anyway, but if I were the warranty manager, things would be different.

You'd never know what somebody was shooting, unless they told you.

He just told the WHOLE FREAKIN' WORLD, and if he ships the "offensive" casing back with the gun, then I guess the guys at S&W will figure it out.

If I put diesel fuel in my gasoline engine truck, should I expect GMC to fix it for me?

JEEEzus folks, READ the manual, and follow directions, or assume the consequences.

Don't worry, figure S&W will fix it, and pass on the costs of the repair, and untold others to the people who buy new ones.

they said it would not run consistently or reliably, and that they don't recommend them, it didn't say to Not use them.
plus i don't see how a underpower round could cause a oob discharge.

Matt, You beat me to it. I have a 15-22 and read the manual. The manual warns about certain ammo that should be be used.

And just because nobody told ever you not to put beans up your nose, is it a wicked good idea to do so??

It has yet to be determined if it is an out of battery fire issue, a defective extractor, fouled chamber bad ammunition, or if it was an obstruction in the barrel. All possible causes are 100% speculation and some highly educated guesses based on a few pictures.

The root cause will most likely remain so for our lifespan unless some pretty heavy duty tests are made and all evidence is provided to the testing authority and and a RCA is issued. As no personal injury happened, most likely S&W will just repair the rifle and send it back.

But posting a thread saying that you used ammunition not recommended in the owners manual and had a problem is part of the reason why the manuals are getting thicker every year. Bottom line, the user was not using recommended ammo

bikerdog · 12-08-2012, 12:56

The reason i was asking about the barrel was because I had a buddy who had something similar happen to him.

He was shooting a smith and wesson 38. While he was shooting he heard a really loud bang. When he checked his gun the cylinder would not turn. It turned out that he had a bad round which had gotten stuck inside the barrel. When he fired a second good round out it struck the bad round and pushed both out of the barrel. But it also blew up the case of the good round.

When you said you where using the quites. I know they are underpowered and most of them are not supposed to be used in rifles.
