However, like any mass-produced firearm, the M&P 15 Sport 2 isn’t without its potential drawbacks. Understanding these potential issues is crucial for ensuring safe, efficient, and enjoyable ownership. This article delves into the common problems associated with the Smith & Wesson M&P 15 Sport 2, providing insights into their causes, potential solutions, and essential maintenance practices. By being informed, owners can proactively address these problems and maximize the rifle’s performance and longevity.
Unraveling Common Reliability Problems
Reliability is a cornerstone of any firearm. Owners of the Smith & Wesson M&P 15 Sport 2 should be aware of potential issues that can impact its consistent function. These often stem from mechanical factors, the ammunition being used, or a combination of both.
Feeding Frustrations
One of the most commonly encountered issues with the M&P 15 Sport 2, and many AR-15s in general, is a failure to feed. This occurs when the rifle fails to chamber a round from the magazine. Several factors can contribute to this problem. One primary culprit is the magazine itself. Inconsistent magazine quality, wear and tear, or even simply using a magazine not designed to work optimally with the rifle, can all contribute to feeding issues. Checking the magazine for damage, ensuring it’s properly seated, and experimenting with different magazine brands is a crucial first step.
Another potential cause is the ammunition. Using low-quality ammunition, or ammunition that doesn’t meet the rifle’s specifications, can sometimes lead to feeding problems. Furthermore, the way the rifle is lubricated and the condition of the recoil spring also play important roles. A weak or worn recoil spring can fail to provide the necessary force to strip a round from the magazine and chamber it. Likewise, insufficient lubrication or an overly dry chamber can impede the smooth movement of components. Thorough cleaning, lubrication, and ensuring the rifle has a good recoil spring are vital components.
Ejecting Challenges
Another common issue is a failure to eject the spent casing. This can manifest in several ways, including the spent casing getting stuck in the chamber, the bolt failing to extract the casing at all, or the rifle extracting the casing but failing to cycle the next round.
Causes of this problem can include gas system malfunctions. The gas system is responsible for cycling the action of the rifle. If the gas block is not properly aligned or has come loose, the rifle may not receive enough gas pressure to cycle correctly. Inadequate gas pressure can lead to under-extraction. Similarly, problems with the extractor, the component responsible for pulling the spent casing from the chamber, can cause issues. An extractor that is worn, damaged, or not properly gripping the casing can result in a failure to eject. Moreover, a dirty chamber, with excessive carbon buildup, may not allow smooth casing extraction. Regular cleaning, inspection of the gas system, and extractor maintenance are essential to prevent these failures.
Firing Failures
A third category of reliability issues relates to the firing process. These failures manifest as the rifle failing to discharge a round when the trigger is pulled. Light primer strikes, where the firing pin doesn’t generate enough force to ignite the primer, are often to blame. This can be caused by several factors, including a damaged firing pin, insufficient lubrication on the firing pin, or a weak hammer spring. Careful inspection of the firing pin, ensuring it moves freely and isn’t obstructed by debris, is critical.
Additionally, the ammunition itself may be at fault. Defective ammunition with improperly seated primers might not fire. Furthermore, even when all the mechanical parts are fine, something as simple as the angle with which the ammunition is put into the rifle can cause issues with the firing process.
Considering Potential Manufacturing Concerns
Beyond operational reliability, potential quality control issues should be acknowledged. These concerns, while not universal, can still impact an owner’s experience.
Fit and Finish Questions
One concern is the overall fit and finish of the rifle. While Smith & Wesson strives to maintain a high standard, some owners have reported that the fit between the upper and lower receiver isn’t always perfectly tight. A loose fit can be problematic. It may potentially affect accuracy, and it might feel less sturdy.
Additionally, there might be cosmetic imperfections, like minor scratches or machining marks, on the receiver or other parts. These cosmetic flaws aren’t usually indicative of performance problems, but it’s useful to know what to expect and what questions to ask before purchasing.
Trigger Troubles
The trigger is a critical component in any firearm. The standard trigger in the M&P 15 Sport 2 is generally adequate, but some owners find the pull weight to be heavier than they’d prefer. The trigger feel may also be gritty, with a less-than-smooth pull. The breaking point of the trigger may be inconsistent, which makes accurate shooting more difficult. While the trigger is generally functional, the stock design isn’t the best, so it’s important to know how to adjust it properly or replace it.
Gas System Issues
The gas system, crucial for the rifle’s function, can sometimes present issues. Gas blocks can potentially come loose over time, particularly if not installed with proper care during the initial assembly. This can lead to reduced gas pressure and cycling issues. Also, gas tube failures, while less common, can also prevent proper function.
Analyzing Accuracy Expectations
Accuracy is a significant factor for any firearm owner. However, the M&P 15 Sport 2 is typically not designed to compete with high-end precision rifles.
Accuracy Limits
The M&P 15 Sport 2, in its basic form, is generally capable of achieving acceptable accuracy for its intended purpose, which is primarily defensive and recreational shooting. However, due to factors like barrel quality, twist rate, and the absence of features found in more expensive rifles, its inherent accuracy capabilities might be more limited compared to some other AR-15 models.
Evaluating Group Size and Consistency
The group size—the spread of bullet impacts on a target—is an essential measure of accuracy. The M&P 15 Sport 2 is generally capable of producing groups of a reasonable size. However, factors like ammunition choice, shooting technique, and environmental conditions can significantly influence group size. Understanding the limitations and maximizing the factors under your control, like practicing proper shooting techniques and experimenting with different ammunition brands, will optimize the accuracy of this rifle.
Essential Maintenance and Best Practices
Ensuring the long-term reliability and performance of the M&P 15 Sport 2 requires consistent maintenance.
Regular Cleaning and Inspection
Thorough and regular cleaning is paramount. After each shooting session, the rifle should be field-stripped and cleaned. Pay particular attention to the chamber, bolt carrier group, and barrel. Carbon buildup, dirt, and debris can negatively impact performance and lead to malfunctions. Make sure to use high-quality gun cleaning supplies and follow the manufacturer’s instructions carefully.
Component Care and Lubrication
Proper lubrication is also vital. Use a high-quality gun oil or lubricant, and apply it sparingly to the appropriate parts, like the bolt carrier group rails and the trigger components. Over-lubrication is just as bad as under-lubrication. Excess oil can attract dirt and debris. Check the instruction manual and ensure that all components are well-oiled to maximize performance.
Avoiding Common Mistakes
There are mistakes that can detract from proper functioning. Avoid under-lubrication, and also avoid using low-quality ammunition or ammo that is unsuitable for the rifle’s specifications. These mistakes can lead to jams, failure to eject, or failure to fire.
User Insights and Feedback
Exploring the experiences of other owners can be a valuable source of insight.
