Now, let’s dive further into the details:
1. Hammer Fails to Cock
Sometimes, when you pull the trigger of a gun, it may not shoot. This can happen because the gun’s mechanism called the bolt, is still locked in place after the previous bullet was fired. This causes the hammer to be ready to strike again, but it prevents a new bullet from entering the firing position.
The cartridge is ejected but the hammer still does not cock.
How to solve this problem?
To fix this problem, here is what you need to do!
- Hold the trigger in position and then insert the hammer trigger pin.
- From the left side install the ungrooved end.
- The hammer needs to be placed into the receiver resulting in the spring legs resting on the pin.
- Now, you need to insert the hammer pin into the right place using the hammer.
- Make use of a hammer block, test it, and cock the hammer to check if the issue is resolved.
2. Over-Gasing Can Cause Burns on the Face!
It is a major problem when 5 or more rounds are fired in a single burst. This occurs especially when firing in a 2 or 3 o’clock form due to the strong recoil impulse. The gas ejected can cause burn damage.
How to solve this problem?
To avoid this, here is what you need to do!
- Adjusting the gas pressure by making changes to the gas block control can help.
- If your rifle does not have an adjustable gas block then change it.
- Change the gas pressure as per need and the excess carbon won’t build up to create force on the rifle components.
3. Trigger Catching Due to Manufacturing Faults
Burns along the material will sometimes result in a trigger stuck. Be sure to break the gun (a process to smoothen the rough spots within the barrel after manufacturing).
How to solve this problem?
Here is the method to fix it!
- After purchasing the rifle, perform the breaking process.
- You need to fire 200-300 rounds minimum before assuming that the rifle is safe for self-dense use.
- Lubricate or grease the critical parts of the gun.
4. Problems When Firing the Rifle: Is the Firing Pin Okay?
A very common problem with all rifles is the firing issue. This can happen with any rifle and not just the Smith and Wesson M&P 15 Sport II. You can fix it like this!
How to solve this problem?
Check the firing pin and its condition and do this!
- Step 1: Take out the bolt and inspect if the firing pin is there.
- Step 2: Remove the bolt and clean it thoroughly.
- Step 3: Identify if the tip of the pin (firing) is broken.
5. Bolt Carrier Group and Failure to Feed Rounds
This problem occurs when the bolt carrier group does not work properly. The reason? Manufacturing errors! An incorrect form is identified in the extractor. The brass may catch the extractor.
How to solve this problem?
Here is a quick fix to it!
- Changing the bolt carrier group is one way to fix it.
- The extractor should be replaced immediately as it scrapes and damaged the brass.
- You can send the gun to the manufacturer for a fix as you get a lifetime warranty on purchase.
6. Heavy Barrel and Threaded Barrel Resulting in Tilts
The barrel may be heavy and you can notice that the rifle will tilt to the front causing inaccuracy while shooting.
Is this a serious problem?
Shooters need practice for a few weeks with the Smith and Wesson M&P 15 Sport 2 to get used to the heavy barrel weight. New shooters have to manage the tilting and adjust to a form that gives them more balance.
7. Destabilization of Form Due to Tumbling Bullets
Firing a round from the Sport 2 can result in a tumbling bullet. A single occurrence is not a problem but after shooting consecutive rounds of ammunition it can be serious. A tumbling bullet means that the bullet starts to rotate around its long axis after it is fired.
How to solve this problem?
Here is how you fix this!
- Check the barrel for any copper fouling deposits.
- To get rid of the copper that has collected due to the firing of several rounds you need to use a chemical copper remover.
- Consulting a bore guide clean the barrel properly.
- On a temporary basis, you can use another type of rifle ammunition.
8. Barrel Twist Causes Inaccuracy
A 1 in 9″ barrel twist is equipped in the Smith and Wesson M&P 15 Sport 2. Normally, this type of twist does not cause any issue. But, for people familiar with a 1 in 7″ twist it can be hard to adjust. Here are some amazing fixes to this!
How to solve this problem? (Why is a 1 in 9” barrel twist a recommended choice)
Here is how you fix this!
- Check the barrel twist rate and ensure you’re using ammunition suitable for that twist rate.
- Experiment with different bullet weights to find ones that stabilize better with your barrel’s twist rate.
- Inspect the barrel for any damage, erosion, or excessive wear.
The shooter will not be able to accurately shoot the target if this happens. A heavy bullet with a faster twist rate is ideal to use.
9. Extracting Problem Caused by Bullet Jamming
While firing the ammo can jam into the chamber. This happens in newly purchased firearms. The next round is unable to feed into the chamber.
How to solve this problem?
You can fix it by doing this!
- Step 1: Remove the extractor and bolt.
- Step 2: Check the o-ring beneath the extractor for damage or if it is missing.
- Step 3: Swap the o-ring (for better grip on the rim).
- Step 4: Double-check every and re-assemble.
