Smith and Wesson M&P 15 Sport 2 Problems and Their Practical Solutions

1. Extraction Problem:

First, owners may encounter an extraction problem. During a trip to the range, you gear up and are ready to shoot. You may find that the ammo gets jammed in the chamber.

This can be frustrating, especially when you’re hoping for a smooth shooting experience. It’s not something you expect with brand-new firearms out of the box.

When a spent casing fails to extract, it disrupts the shooting flow and messes with your aim. The results? It takes away from the fun of shooting.

To fix the extraction issue, the owners took off the bolt carrier group and removed the extractor to inspect it closely.

It turned out that the o-ring was missing, and there was a tiny piece that seemed damaged.

This was causing a major headache, as the gun was not behaving as it should. The gun started behaving much better after replacing the damaged parts.

They went to the range and tested it with several mags, and there was not a single extraction issue.

Trust me, checking the extractor is the main point.

2. Feeding Issue:

Next, owners experienced a feeding issue. After firing several rounds, the chamber seemed to have trouble cycling properly. It brought the shooting experience to a grinding deadlock.

Upon inspection, it appeared that there might have been a manufacturing error with the bolt carrier group. It was possibly an improperly formed extractor.

This resulted in brass getting caught and throwing off the whole shooting experience.

Trust me, it happened frequently enough to cause concern.


Fear not; there’s a solution. It’s advisable to return the rifle to Smith and Wesson under their limited lifetime warranty.

They will replace the faulty components, such as the bolt carrier group or extractor. After getting it replaced and back from Smith and Wesson, the difference can be night and day.

At the range, you’ll notice a change in performance. What was once a hesitation due to feeding issues becomes a smooth shooting experience.

Then, you’ll be back to enjoying your rifle with no time wasted.

3. Hammer Issue:

The next concern is the hammer issue. Okay, you aim and squeeze the trigger, and nothing happens.

It is quite a downer as I try to figure out the cause. The cartridge fails to discharge because the hammer does not engage properly.

In simpler terms, the bolt does not engage. It leads to a frustrating moment where owners cannot focus on their target.


To fix the hammer problem, I watched a YouTube video demonstrating how to do it. The process involves replacing the hammer and trigger pin.

While it may seem complex at first, the video makes it straightforward.

Insert the new hammer trigger pin and place the trigger in the proper position. Take it to the range for a test run.

The problem is solved, and the hammer is now cocked perfectly.

Now, owners no longer face the issue and can confidently say that the replacement is the trick to resolving the problem.

4. Problem with the Firing Pin:

A showstopper? Yes, it is a firing pin issue. Imagine being at the range, all lined up and ready to fire. It is only to hear a hollow click instead of the expected bang.

This vexing problem can turn what should be an exhilarating shooting session into a disappointment.

It’s a problem that often sneaks up on users. It disrupts their shooting rhythm and creates a buzzkill atmosphere.

Such less-than-ideal occurrences can make the range experience less enjoyable.


Okay, so after wasting time attempting to troubleshoot the problem, the owners realized they needed professional help. They returned the rifle to the manufacturer, and they promptly provided a replacement that took care of the issue.

Upon getting it back, they took it to the range. It felt like a whole new gun.

So, don’t hesitate to send it back for a replacement. It can save time and headaches in the long run.

5. Issue with the Tumbling Bullets:

Ahh, the tumbling bullets. Instead of flying straight, these bullets tend to do somersaults in mid-air. It can be a big deal when aiming.

It’s not just annoying; it can create a mess on the range. Have you noticed this happening frequently after rounds are fired? It indicates that your rifle is acting up. It is possibly due to wind or other factors.


There are some steps you can take to address them.

  • First, check the inside of the barrel for copper fouling.
  • Use a chemical copper remover to clean up any gunk accumulated from frequent firing.
  • Consider using a bore guide to ensure a thorough cleaning process.
  • Further, switching to a different ammo may provide a temporary solution.

However, for a long-term fix, it’s essential to ensure you’re regularly cleaning out the barrel and maintaining good barrel cleaning practices.

6. Trigger Issue:

Last and foremost, it is the trigger getting stuck. When trying to pull the trigger, it feels like it’s not budging. It gives off an unsettling feeling.

This letdown is particularly noticeable at the range. Here, even small imperfections or burrs seem to be causing the trigger to catch.


Simple solutions are available.

  • Firstly, it’s essential to properly lubricate your rifle. Ensure that the trigger mechanism is well-lubed.
  • Consult your user manual for guidance on the proper lubrication process, and be sure to apply grease as recommended.

You can ensure that the problem pretty much vanishes. It allows for smoother and more enjoyable shooting experiences.

My Final Conclusion:

Okay, so it’s time to get real about its performance. While it may not be perfect, it does share some issues commonly reported by users. These include extraction problems, jamming issues, feeding concerns, and finicky triggers.

However, these are fixable with a little help and some patience. One glitch that stood out was the tendency for the triggers to ride. But this can be addressed with some adjustments.

Fortunately, Smith and Wesson’s warranty service is there to assist when needed. It makes any challenges worth the effort.

Overall, the Smith and Wesson M&P 15 Sport 2 remains a reliable, affordable, and enjoyable firearm once its quirks are tackled head-on.

One common issue reported is that the rifle constantly jams and fails to eject properly. It leads to frustration during shooting sessions.
