The Smith & Wesson M&P 15 is a popular and reliable AR-15 platform rifle, appreciated for its affordability and solid performance. However, like any firearm, there's always room for improvement. This guide explores the best M&P 15 upgrades to enhance accuracy, ergonomics, reliability, and overall shooting experience. We'll cover everything from essential upgrades to more advanced modifications, helping you tailor your M&P 15 to your specific needs and shooting style. This guide focuses on practical, high-impact upgrades that offer significant improvements without breaking the bank.
Essential M&P 15 Upgrades: Foundational Improvements
These upgrades are recommended for nearly every M&P 15 owner, regardless of experience level or intended use. They address common shortcomings and significantly improve the rifle's functionality.
Upgrading the Trigger: Smooth Operation and Improved Accuracy
The stock M&P 15 trigger is often criticized for its gritty feel and long pull. A significant upgrade is replacing it with an aftermarket trigger. Options range from drop-in triggers for easy installation to more complex, adjustable triggers requiring gunsmithing skills.
-
Why upgrade? A better trigger reduces pull weight, shortens the reset, and provides a cleaner break, leading to improved accuracy and faster target acquisition.
-
Top choices: Consider brands like Geissele, CMC Triggers, and ALG Defense. Research reviews to find a trigger that suits your preferences and budget. Many users report significant improvement in accuracy after an upgraded trigger.
-
Installation: Some drop-in triggers are simple enough for DIY installation with basic tools. Others may require professional assistance.
Enhancing the Handguard: Improved Ergonomics and Accessory Mounting
The standard M&P 15 handguard is functional but may lack the versatility and ergonomics of upgraded options. Replacing it with a free-floating handguard opens up possibilities for accessory mounting and improved heat dissipation.
-
Why upgrade? Free-floating handguards prevent the handguard from contacting the barrel, minimizing vibrations and improving accuracy. They also offer more space for mounting accessories like lights, lasers, and vertical grips.
-
Key features: Look for handguards made from lightweight and durable materials like aluminum or polymer. Consider the length and rail system (M-LOK or KeyMod) based on your needs.
-
Installation: Handguard replacement requires basic tools and some mechanical aptitude. Consult your chosen handguard's instructions for specific guidance.
Improved Optics: Enhanced Sight Picture and Accuracy
The iron sights on the M&P 15 are serviceable, but upgrading to an optic dramatically improves target acquisition and accuracy, especially at longer ranges.
-
Why upgrade? An optic provides a clearer sight picture, faster target acquisition, and improved accuracy at distance compared to iron sights.
-
Top choices: Red dot sights (RDS) are popular for their versatility and ease of use. Magnified optics are beneficial for longer-range shooting. Consider your budget and intended use when selecting an optic.
-
Installation: Optic mounting requires careful attention to zeroing and proper mounting hardware. Professional assistance is recommended if you're inexperienced.
Advanced M&P 15 Upgrades: Fine-Tuning Your Rifle
These upgrades are geared toward more experienced shooters seeking to maximize their rifle's performance. They often require more technical knowledge or specialized tools.
Upgrading the Bolt Carrier Group (BCG): Increased Reliability and Longevity
The BCG is the heart of the AR-15 platform, and a high-quality BCG ensures reliable function.
-
Why upgrade? Upgraded BCGs are typically made from higher-quality materials, such as nickel boron or chrome-lined steel, for increased durability and longevity. They often offer smoother operation and improved reliability.
-
Top choices: Consider brands known for their high-quality BCGs, such as BCM, Toolcraft, and JP Enterprises. These are usually more expensive than stock BCGs, but worth the investment for extended lifespan.
-
Installation: BCG replacement is straightforward for someone comfortable with AR-15 maintenance. Consult a qualified gunsmith if you are not confident.
Enhanced Charging Handle: Smoother Operation and Improved Ergonomics
The standard charging handle can be awkward to manipulate, especially under stress. An upgraded charging handle offers smoother operation and improved ergonomics.
-
Why upgrade? Upgraded charging handles often feature larger, more comfortable latches and smoother operation. Some offer ambidextrous operation for easier use by both left-handed and right-handed shooters.
-
Top choices: Radian Raptor charging handles are popular for their ambidextrous operation and smooth action.
-
Installation: Replacing the charging handle is a simple task.
Improved Stock: Enhanced Comfort and Adjustability
The stock is a crucial component for proper shooting posture and comfort. An upgrade can provide superior adjustability and comfort.
-
Why upgrade? Upgraded stocks often offer adjustable cheek rests and length of pull for a customized fit. This enhances comfort and shooting accuracy.
-
Top choices: Magpul stocks are a popular and affordable choice. More advanced stocks offer features such as integrated storage compartments or battery packs.
-
Installation: Stock replacement is typically straightforward, requiring minimal tools.
Case Study: A Practical Upgrade Approach
Let's consider a scenario where a shooter primarily uses their M&P 15 for home defense and occasional range practice. A practical approach might prioritize the following upgrades:
- Trigger: Replace the stock trigger with a drop-in trigger for improved accuracy and smoother operation.
- Optic: Install a red dot sight for quick target acquisition.
- Handguard: Replace the standard handguard with a free-floating M-LOK handguard for enhanced ergonomics and accessory mounting.
- Vertical Grip: Add a vertical grip for improved control and stability.
This combination significantly enhances the rifle's usability and performance without requiring extensive gunsmithing skills or a large budget.
Conclusion: Choosing the Right M&P 15 Upgrades
Upgrading your M&P 15 is a rewarding experience that can significantly enhance your shooting experience. Prioritize essential upgrades first, focusing on trigger, optics, and handguard improvements. Then, consider advanced upgrades based on your shooting style and budget. Always remember to consult your firearm's owner's manual and seek professional assistance if needed. By strategically choosing your upgrades, you can transform your M&P 15 into a precision instrument perfectly tailored to your needs.
