1. Hammer Not Cocking:
When you squeeze the trigger on the Smith and Wesson M&P 15 Sport 2, it may not always shoot.
The hammer is the source of this issue. The fundamental cause is that the hammer was not cocked when the cartridge was discharged.
This normally occurs when the bolt is engaged as a result of the prior round’s firing.
The empty case from the previous round will be expelled, but the hammer will not cock. To resolve this issue, you must replace the hammer.
Insert one hammer trigger pin after placing the trigger into position. Install the ungrooved end from the left side first (Fig 1).
Place the hammer into the receiver so that the spring legs rest on the pin. Insert the hammer pin into position using a hammer. Now, cock the hammer and test it with a hammer block.
2. Trigger Catching:
The trigger of the Smith and Wesson M&P 15 Sport 2 occasionally becomes stuck. This is caused mostly by burrs along the material.
This is a problem with S&W’s new assault rifles, particularly this one. If you shoot the gun without breaking it in, the trigger will occasionally catch.
To resolve this issue, you must break in the rifle immediately after acquiring it. Remember that you must shoot at least 200 to 300 rounds at the range before bringing it out for self-defense.
Lubricant and grease should also be applied to the appropriate locations of your assault weapon. For optimal lubrication procedure, consult your user manual.
3. Failure to Feed:
The failure to feed problem can occur with the Smith and Wesson M&P 15 Sport 2. This generally happens when there is an issue with the bolt carrier group.
In particular, a manufacturing error might result in the extractor that is included with the bolt carrier group having the incorrect form. The brass catches on the extractor as a result, bringing in this problem.
The Smith and Wesson M&P 15 Sport 2’s bolt carrier group must be changed to resolve this problem. You should change the extractor as soon as possible since it bends and scrapes the brass.
To solve this problem, send the rifle to S&W. They provide a limited lifetime warranty, so they will address the problem.
4. Tumbling Bullets:
You could experience issues with tumbling bullets when you shoot your Smith and Wesson M&P 15 Sport 2 more frequently. The fired round spins about its short axis in the path of motion when this occurs.
This problem might not bother you as much at first. But when you fire more bullets, it will happen more frequently.
Inside the barrel, you should search for copper fouling accumulations. To remove the copper that has built up after firing several rounds, use a chemical copper remover.
Additionally, you need to clean the barrel and utilize a bore guide. While using alternative rifle ammunition may help to lessen tumbling, this is not a long-term fix.
5. Extracting Problem:
When using the Smith and Wesson M&P 15 Sport 2, ammunition may become jammed in the chamber. Newer firearms have this issue right out of the box.
This problem prevents the subsequent round from feeding. You should clean the rod to remove the trapped round.
First, take off the extractor and bolt. The o-ring underneath the extractor might be damaged or missing.
To improve your grip on the rim, replace the o-ring. You can install the AR 15 o-ring from Brownells.
