We’ll explore the various components you can swap, the benefits each upgrade offers, and provide practical advice to guide your choices.
Understanding Your M&P 15: A Crucial Starting Point
Before you embark on the journey of upgrades, it’s essential to understand your starting point. The M&P 15, as mentioned, is built on the AR-15 platform, and as such, possesses a standard layout, making it compatible with a wide variety of aftermarket parts. Getting acquainted with your rifle’s specifications and knowing its existing weaknesses is key to planning the best upgrades.
The basic design of your M&P 15 typically includes a direct impingement gas system, a carbine-length gas system (though some models might vary), a forged or sometimes cast upper and lower receiver, and a standard A2-style flash hider. Examine the barrel length and twist rate (often 1:9 or 1:8, influencing bullet choices). These parameters will influence your upgrade paths.
When assessing your rifle, consider its strengths and areas where improvement is possible. Many factory triggers, for instance, are serviceable but might benefit from a lighter pull and crisper break. The standard stock, while functional, might not offer the best ergonomics for every shooter. Likewise, the handguard, often a basic polymer or a simple metal design, limits accessory mounting options and can sometimes impact comfort. The grip, as well, can sometimes be a point of improvement, especially if you have larger hands or prefer a more aggressive texture.
Safety is paramount. All firearms should be treated with the utmost respect. Always ensure your firearm is unloaded and the action is open before performing any work. Consider seeking professional gunsmithing assistance if you’re unsure about any installation steps. Installing the Best M&P 15 Upgrades is an investment in your rifle and safety should always be your top priority.
Elevating Your Rifle: The Core Upgrades
Now, let’s dive into the heart of the matter: the Best M&P 15 Upgrades. This section will delve into the most impactful changes you can make to your rifle.
Trigger Transformations: Sharpening Your Accuracy
The trigger is the interface between you and your rifle, directly influencing shot placement. A superior trigger enhances accuracy by allowing for a cleaner, more predictable break. This means a lighter pull weight, a shorter travel distance, and a crisp reset. The standard trigger in an M&P 15 is usually functional, but upgrading can dramatically improve your shooting experience.
There are primarily two routes you can take:
Drop-in triggers
These units replace your entire trigger group with a pre-assembled, high-quality trigger. They’re easy to install, often dropping right into the receiver with minimal effort. Examples of reputable drop-in trigger brands include Geissele, Timney, and Rise Armament. These triggers typically offer single-stage or two-stage configurations, each catering to different shooting styles. The downside is the cost; drop-in triggers are often the priciest trigger upgrades.
Trigger components
This method involves replacing individual trigger parts, like the hammer, sear, or trigger springs. These components are designed to be less costly than drop-in triggers. Installation, however, requires more mechanical ability and knowledge of how AR-15 trigger mechanisms function. This approach lets you fine-tune your trigger pull characteristics without requiring a complete replacement.
The Best M&P 15 Upgrades in this category often involve a smooth, crisp trigger.
Handguard Overhauls: Ergonomics and Versatility
The handguard is another critical component. A well-chosen handguard significantly improves the ergonomics of your rifle, enabling a more comfortable and controlled grip. Simultaneously, it provides mounting platforms for accessories like lights, lasers, vertical grips, and bipods. Upgrading your handguard opens up a world of customization possibilities.
Consider the following when selecting a handguard:
Free-float vs. non-free-float
Free-float handguards do not make contact with the barrel. This eliminates pressure on the barrel from the handguard, contributing to improved accuracy. Non-free-float handguards mount to the delta ring and handguard cap and are more budget-friendly.
Material
Handguards are typically made from aluminum or carbon fiber. Aluminum is durable and offers good heat dissipation. Carbon fiber handguards are lighter and often more expensive.
Mounting Systems
Three major mounting systems are frequently employed in modern handguards. M-LOK, KeyMod, and Picatinny (MIL-STD-1913) rails. M-LOK and KeyMod offer a more streamlined profile and allow for direct accessory attachment, minimizing bulk. Picatinny rails offer a full length mounting platform.
When looking for the Best M&P 15 Upgrades for handguards, research the features available. This should include the quality of the materials used, the mounting capabilities, and the weight.
Stock Solutions: Comfort and Control
The stock has a significant role in how your rifle fits you and how comfortably you can shoot. A well-designed stock provides a solid cheek weld, enhances shouldering comfort, and contributes to better recoil management.
Consider these points when selecting a stock:
Adjustability
Adjustable stocks (collapsible) offer flexibility for shooters of different sizes or those using different gear (like body armor). Fixed stocks offer robust construction and a consistent cheek weld.
Material
Stocks are often made from polymer, which is durable and lightweight. Some stocks are made from aluminum, which is even more robust.
Features
Look for features like QD (Quick Detach) sling attachment points, storage compartments, and an adjustable length of pull (LOP).
For the Best M&P 15 Upgrades, prioritize a stock that provides a comfortable and secure fit.
Grip Enhancements: Maximizing Hand Control
The grip, the point of contact between your hand and the rifle, is important for control. A grip that fits your hand well and provides a secure hold is critical for both comfort and control, especially in dynamic shooting scenarios.
Material
Grips are generally made of polymer or rubber. Polymer grips are tough and affordable, while rubber grips can provide enhanced grip and feel.
Features
Look for finger grooves, textured surfaces, and storage compartments (for batteries or other small items).
The right grip is among the Best M&P 15 Upgrades because it has a direct effect on the weapon’s control.
Sight Selection: Aiming for Precision
The sighting system is perhaps the most crucial factor in hitting your target. Upgrading the sights on your M&P 15 can dramatically increase accuracy and target acquisition speed.
Iron Sights
Iron sights, like the classic A2 style, are durable, reliable, and require no batteries. Upgraded iron sights often feature better sight pictures (e.g., more precise front sight posts, improved rear aperture) and better adjustability.
Optical Sights
There is a wide variety to choose from.
Red Dot Sights
These are compact, fast-acquiring, and excellent for close- to mid-range shooting.
Scopes
Scopes magnify the target, increasing accuracy at longer distances. Low-power variable optics (LPVOs), with magnification ranging from 1x to 6x or 1x to 8x, offer great versatility.
Magnifiers
Magnifiers can be paired with red dot sights to offer additional magnification when needed.
The right sighting system is crucial for the Best M&P 15 Upgrades and is tied to the intended use.
Bolt Carrier Group Upgrade: Reliability and Durability
The bolt carrier group (BCG) is the heart of your rifle’s operating system. Upgrading the BCG is a smart move to improve reliability and overall performance.
When selecting a BCG, consider:
Materials
Look for BCGs made from high-quality steel, like Carpenter 158 for the bolt, and 8620 steel for the carrier.
Coatings
Coatings like Nickel Boron (NiB) or DLC (Diamond-Like Carbon) reduce friction, increase corrosion resistance, and make cleaning easier.
Inspections
Ensure the BCG has undergone proper testing (e.g., magnetic particle inspection – MPI) to detect defects.
A robust BCG upgrade is one of the Best M&P 15 Upgrades for added assurance.
Charging Handle Upgrades: Ease of Use
The charging handle is another frequently overlooked component. A better charging handle will facilitate easier operation and will improve overall usability.
Ambidextrous Designs
Ambidextrous charging handles are useful for both left- and right-handed shooters and for quick manipulation of the rifle.
