A Closer Look at the Smith and Wesson m&p 15 Sport 2 Problems
Now let’s look at the main problems associated with the Smith and Wesson m&p 15 Sport 2.
Firing pin issue
Just like the Springfield Hellcat, the firing pin issue is a problem that has been reported by some owners of the Smith and Wesson M&P 15 Sport 2 rifle.
The firing pin is a small, spring-loaded component responsible for striking a cartridge’s primer, igniting the gunpowder, and firing the bullet.
In some cases, the firing pin on the M&P 15 Sport 2 can become stuck in the forward position, preventing the rifle from firing.
What Causes the Firing Pin issue?
A few things can cause the firing pin issue on the M&P 15 Sport 2. One possibility is that the firing pin is made of weak material and can bend or break easily.
Another possibility is that the firing pin spring is not strong enough to push the firing pin forward.
It is also possible that there is a problem with the bolt carrier group, which is the part of the rifle that houses the firing pin.
Things you can do to try and fix the firing pin issue
If you are experiencing the firing pin issue on your M&P 15 Sport 2, there are a few things that you can do to try to fix the problem.
First, you can try to clean and lubricate the firing pin and bolt carrier group.
If that does not work, you may need to replace the firing or firing pin spring. In some cases, replacing the bolt carrier group may also be necessary.
If you are experiencing the firing pin issue on your M&P 15 Sport 2, it is important to take it to a qualified gunsmith to repair it. Attempting to repair the rifle yourself could potentially make the problem worse.
Tips to help Prevent the Firing pin Issue on the M&P 15 Sport 2
- Clean and lubricate the firing pin and bolt carrier group regularly.
- Use high-quality ammunition.
- Avoid dropping or banging the rifle.
- If you experience any problems with the rifle, take it to a qualified gunsmith for repair.
Barrel weight
The barrel weight is one of the most common complaints about the Smith and Wesson M&P 15 Sport 2.
The front of the barrel is heavier than the rear, which can cause the rifle to tilt forward when shouldered. This can make keeping the sights on target difficult, especially during rapid fire.
Why does the M&P 15 Sport 2 have a Heavier Barrel?
There are a few reasons why the M&P 15 Sport 2 has a heavier barrel. One reason is that the barrel is made of a thicker, stronger material. This is done to improve the accuracy and durability of the rifle. However, it also makes the barrel heavier.
Another reason for the heavier barrel is that the M&P 15 Sport 2 is designed to be used with a suppressor. Suppressors add weight to the front of the rifle, so the barrel is made heavier to compensate.
What can you do to Solve the Issue of Barrel Weight?
A few things can be done to reduce the barrel weight of the M&P 15 Sport 2. One option is to replace the barrel with a lighter-weight model. However, this can be expensive and may void the warranty on the rifle.
Another option is to add a weight to the rear of the rifle. This will help balance the barrel’s weight and make it easier to keep the sights on target. However, this can also make the rifle more front-heavy, making it difficult to maneuver.
The best option for reducing the barrel weight of the M&P 15 Sport 2 is to use lighter-weight ammunition. This will reduce the rifle’s recoil and make it easier to control. It will also reduce the wear and tear on the barrel, which can help to extend its lifespan.
Tips to help Reduce the Barrel Weight of the M&P 15 Sport 2
- Use lighter-weight ammunition.
- Add a weight to the rear of the rifle.
- Replace the barrel with a lighter-weight model.
It is important to note that reducing the barrel weight of the M&P 15 Sport 2 may affect the accuracy and durability of the rifle. It is important to weigh the pros and cons before making any changes.
Issues with Barrel Twist
The Smith and Wesson M&P 15 Sport 2 is a popular AR-15 rifle, but it has been known to have issues with barrel twists.
Barrel twist refers to the rate at which the rifling in the barrel rotates the bullet as it travels down the barrel.
The twist rate is measured in inches per turn, and it is important to match the twist rate to the weight and shape of the bullet being fired.
If the twist rate is too slow, the bullet will not stabilize and will tumble in flight, leading to inaccurate shooting.
If the twist rate is too fast, the bullet will spin too quickly, leading to inaccurate shooting.
The M&P 15 Sport 2 has a 1:9 twist barrel and a good all-around twist rate for 5.56x45mm NATO ammunition.
However, some shooters have reported that the rifle has difficulty stabilizing heavier bullets, such as 77-grain bullets. The 1:9 twist rate is not fast enough to stabilize these heavier bullets.
What can you do to try and Solve Issues with Barrel Twist?
If you are experiencing accuracy problems with your M&P 15 Sport 2, you may want to try using different types of ammunition. If you use heavier bullets, you may want to try using a barrel with a faster twist rate.
You can also try using a different brand of ammunition, as different brands can have different manufacturing tolerances, which can affect the weight and shape of the bullets.
Tips to help avoid Issues with Barrel Twists
- Use ammunition that is designed for your rifle.
- Use a variety of ammunition to see what works best for your rifle.
- Try using a barrel with a different twist rate.
It is important to note that barrel twist is just one-factor affecting accuracy. Other factors, such as the quality of the barrel, the shooter’s technique, and the environmental conditions, can also affect accuracy.
Over Gassed
This rifle has been known to have a problem with over-gassing. Over-gassing occurs when the rifle is given too much gas, which can cause many problems, including:
- Increased recoil
- Increased wear and tear on the rifle
- Reduced accuracy
- Failure to eject spent cartridges
- Failure to feed new cartridges
Things that can Cause Over-gassing
- Using too heavy of a buffer spring
- Using a suppressor
- Using ammunition that is too hot
- Improper installation of the gas system
If you are experiencing any of the problems listed above, your M&P 15 Sport 2 May be over-gassed. There are a few things that you can do to fix the problem, including:
- Switching to a lighter buffer spring
- Removing the suppressor
- Using cooler ammunition
- Having a qualified gunsmith inspect the gas system
It is important to note that fixing the over-gassing problem may not completely solve all of the problems that you are experiencing. However, it should help improve your rifle’s reliability and accuracy.
Tips to Help Prevent Over-gassing
- Use the correct weight buffer spring for your rifle.
- Do not use a suppressor unless it is designed for your rifle.
- Use ammunition that is within the manufacturer’s specifications for your rifle.
- Have your rifle inspected by a qualified gunsmith after any major changes, such as installing a new barrel or gas block.
Understand that over-gassing is just one factor that can affect the reliability and accuracy of your rifle. Other factors, such as the quality of the ammunition, the shooter’s technique, and the environmental conditions, can also affect your rifle’s performance.
Bullet Tumbling
This is a problem that can occur with any rifle, but it is more common with the M&P 15 Sport 2. Bullet tumbling occurs when the bullet rotates out of control after it leaves the rifle barrel. This can cause the bullet to lose accuracy and even change its trajectory.
Things That can Cause Bullet Tumbling
- Using the wrong type of ammunition
- Using a dirty barrel
- Having a gas system that is not tuned properly
- Having a damaged or worn barrel
What can you do to fix Tumbling?
If you are experiencing bullet tumbling with your M&P 15 Sport 2, there are a few things that you can do to fix the problem, including:
- Using the correct type of ammunition
- Cleaning the barrel
- Having the gas system tuned properly
- Having the barrel replaced if it is damaged or worn
It is important to note that fixing the bullet tumbling problem may not completely solve all of the problems that you are experiencing. However, it should help improve your rifle’s accuracy and reliability.
Tips to Help Prevent Bullet Tumbling
- Use ammunition that is designed for your rifle.
- Clean the barrel regularly.
