Had a round go off behind another round with an open chamber

[ransom82]

Ok so i was out yesterday evening playing around with my S&W M&P 15-22. I was sighting in a new 4x20 red star scope i put on it. I had just finished getting the sights dialed in when i had about 5 shots left in the mag. I started to rapid fire them and thats when it happened. A fired round failed to eject and the next cartridge went off behind the empty shell. It was like a cannon going off in my ear. Now, it wont eject the fired rounds from the gun. Should i take this thing in to a smith (maybe a burred barrel at the chamber now) or just call smith & Wesson. It is only about 7 months old.... bought it new at academy in corpus christi, tx.

here are two pics of the "chambered" round previously fired.....

I suspect that you have a damaged extractor (the reason the original round failed to extract). I would contact Smith and Wesson as the gun should never have fired like that. Your gun IS unsafe as it sits right now.

Yeesh, glad you're okay. I agree with G.A. Heath that it may be an extractor problem. I'm guessing the round that went off out of battery did nothing to improve things. That's the curse of rimfire I suppose. I also recommend contacting S&W for customer service.

Interesting...

Just yesterday at the range, my son's S&W .22 pistol had several ftf and fte in a row. On the last one, the rim was partially torn off just like in tthe first picture, and the report was louder than normal. We set the pistol aside and shot other guns, but he was going to give his gun a going over when he cleans it. I'm going to show him this thread.

Ok, I did a little research online and found some other people with extractor problems on this particular rifle. Apparently the extractor is not aligned properly. So i "did the fix".... Now it FTE's every other round. BUT...... If i pull the mag out it will eject every time. The ejector is working, but not with the introduction of the next cartridge into the breach. I am waiting for an email response from S&W in Texas. I'll probably call tomorrow and get this thing figured out.

I have read several posts over the past few months, on various forums, about out of battery discharges with this new S&W 22 rifle. It's a bit disconcerting.

I've fired thousands and thousands of rounds through mine and that's never happened to me.
But someone else at the range has one and he had an extractor problem, basically fell apart on him.
Apparently they did a redesign on the bolt between the time that he bought his and the time I bought mine.
He sent his in and now his has a bolt that looks just like mine.

If you have the previous version of the bolt with the old style extractor, S&W should replace the bolt for you and any other out-dated parts as well..

Do you have a picture of the new style bolt? I'd like to compare it to mine...

[AJ80]

Sure.
I don't remember the exact differences, but it was in the area where the extractor was attached.

Sorry about the bad quality and the dirtiness of the bolt.
I should really clean that thing and then take more pictures.
