M&P 15 Sport. One range trip = sending it to MFG...

[helminator]

Hello all. I am new to these forums. I have recently purchased an M&P Sport. I had it for about a week, watched many videos on cleaning and caring for an AR platform. Performed said cleaning and lubricating (clp). Took the rifle to the range and got very frustrated with constant FTF stoppages. Manually charging would scratch the casing and bullet head and sometimes bend the actual round... After getting a round to chamber. I could get 1-2 rounds down range, before another FTF... I thought I may have been under lubricated so I took it down and cleaned it at the range again. Manually charged the weapon about a hundred times with no ammo. Lubed it till it was dripping, to the same results, tried 3 different ammos all factory brass cased (Independence, Winchester, and PMC)and 3 different (new) Pmags... Any thought as to what may be wrong? I called Smith and they are sending me a shipping label to send it back... I am not sure I feel confident in this weapon... Attached you can see the what the ammo looks like.

I received the rifle back today, you will see the S&W repair report that was in the box. It was not user error (phewww). I will report back when I get to test the repairs.

Just an update for those interested. I went to the range yesterday and ran about 120 rounds through the rifle with zero issues! I used 3 different brands of ammo and 3 different pmags. It seems that the BCG was the issue with my rifle. Glad S&W was able to resolve it quickly (about 2 weeks total turnaround time) and correctly!

Probably the best thing to do at this point. I've run my Sport bone dry with no FTF. Every now and then a bad rifle gets through quality control. Perhaps you ended up with that one. Hopefully they will find the issue.

Sounds like it may be the extractor, but I'm no where near an expert. I'm not even a novice - LOL. I would be interested to know what they say the issue is.

After looking at the picture, that seems to be a feed issue. Especially to bend the rounds like that.

Step 1- Change magazines to a different brand.

Yes I would ask did he try the factory mag as it is not stated. I would think he would have seeing he tried everything else.

 

[helminator]

I did use the factory mag, to the same end result.

 

[helminator]

Even tried a metal mag that a fellow range person let me use, to the same result.

That is a bummer and hopefully S&W will take good care of you. I fired my M&P Sport for the first time yesterday. I had just the opposite experience.

Not a single glitch with my hand loaded 55 grain sierra bullets with IMR-4895 powder. It was a pleasure.

I've seen this issue on several boards, with several brands of firearms, to include Daniel Defense, Colt, and Smith... Unfortunately, the OP never comes back to tell what the final resolution was.

Send it back and S&W will make it right... and let us know what the fix was please!

 

[helminator]

In my research it seems that S&W will send a sheet explaining what work was completed. When that happens I will upload an image, if that does not violate the forum terms.

JUST A GUESS....but it looks like the cartridge is getting wedged into the feed ramps on the way to feed. Perhaps the barrel is set to far back/into the receiver.

Can you take a picture of feed ramp area and post? That would be the chamber area of the barrel as seen through the ejection port.

Better yet, pop the upper off of the lower and take the pic that way.

 

[helminator]

I would if I could. I just dropped it off at FedEx today. I will update the thread when it returns.

That was my experience with a 686 revolver that I've had for 25 years and recently sent in for the firing pin bushing recall. In addition to the requested recall work S&W also did some additional maintenance work on my 686.

When I purchased my Sport via an online seller it was delivered to my FFL with a cosmetic problem on the barrel. I sent it back to S&W under warranty and S&W just replaced the entire upper. Shipping, evaluation, warranty work, and return shipping took about 4 weeks. My new upper is perfectly finished and fits my lower better than the blemished original. Yeah, it's accurate too.

It sure sounds like the feed ramp is out of whack.
Smith will fix it for you and I hope it shoots great when you get it back.

I agree about the feed ramp. The barrel ramp did not line up with the receiver ramp.

 

[helminator]

I am hoping for the best. All my research says that S&W has excellent warranty service. I have an M&P 9 and a Shield in 9mm. I have had zero issues with either firearm, and they each have about 1k rounds through them.

I have the exact same issue with my new sport. The first 50 rounds or so was feeding fine. Then the FTF started. When the round feeds into the chamber after being scratched like that, the bolt doesn't lock. The round gets stuck in the chamber making it almost impossible to get the round out again. And with no forward assist you cant get the round to chamber properly.

I am very disappointed in S&W. I am not in America so i cant just send it back. Please tell us when you get your rifle back what they fixed so i can take my gun to a gunsmith please.

Well just received the rifle back today. Looks like there was an actual issue and not user related (phewww). I will update the thread again when I get to shoot and test the repair. Above you will see the report that was sent by S&W.

If it's new, why would you take it to a gunsmith? Return it to S&W just as the OP did. If it's a factory problem, S&W will fix it for free, no need for a gunsmith.

Because shipping would cost me more than what the gun is worth. On that slip i read that they replaced the BCG. Is this right?
