The Smith & Wesson M&P15 Sport II is a popular and reliable AR-15 platform rifle, perfect for beginners and experienced shooters alike. However, like any firearm, there's always room for improvement and customization to better suit your shooting style and needs. This guide will delve into some key upgrades for your MP15 Sport II, focusing on enhancing accuracy, reliability, and ergonomics.
Enhancing Accuracy: The Foundation of a Great Shot
Accuracy is paramount, and several upgrades directly impact your rifle's precision.
1. Upgraded Trigger: The Heart of Your Shooting Experience
The stock trigger on the MP15 Sport II is functional, but an upgrade significantly improves the feel and consistency of your shots. Consider a drop-in trigger group from reputable manufacturers like Geissele Automatics, CMC Triggers, or ALG Defense. These offer crisper breaks, reduced over-travel, and a more predictable trigger pull, leading to improved accuracy. Research different trigger types (e.g., two-stage, single-stage) to find what best suits your preferences.
2. Enhanced Barrel: The Bullet's Highway
While the factory barrel is adequate, a higher-quality barrel can dramatically improve accuracy and consistency. Look for barrels made from chrome-moly vanadium steel or stainless steel with a 1:7 or 1:8 twist rate (depending on the ammunition you plan to use). Consider barrel length based on your intended use—shorter barrels are more maneuverable, while longer barrels often offer increased accuracy. Remember to ensure compatibility with your existing gas system.
3. Free-Floating Handguard: Stability is Key
A free-floating handguard prevents the barrel from contacting the handguard, reducing vibrations and improving accuracy. This is a significant upgrade, particularly for longer-range shooting. Several excellent options exist, offering varying lengths, rail systems (M-LOK or KeyMod), and materials (aluminum, carbon fiber). Choose a handguard that complements your shooting style and desired accessories.
Reliability Upgrades: Ensuring Smooth Operation
Reliability is crucial for any firearm, and these upgrades ensure your MP15 Sport II functions flawlessly under various conditions.
1. Enhanced Bolt Carrier Group (BCG): The Engine Room
While the factory BCG is typically reliable, a high-quality, nickel-boron coated BCG from a reputable manufacturer like Toolcraft or BCM Gunfighter can significantly improve longevity and reliability. The nickel-boron coating reduces friction, leading to smoother operation and less wear.
2. Gas System Tune-Up: Optimizing the Cycle
Occasionally, the gas system may require adjustment for optimal function, especially when using different ammunition types or accessories. A gas block adjustment or a different gas tube might be necessary to fine-tune the cycling. Consult with a qualified gunsmith if you encounter cycling issues.
Ergonomics and Accessories: Comfort and Functionality
Comfort and ease of use are critical for enjoyable shooting experiences. Several upgrades enhance the overall ergonomics of your MP15 Sport II.
1. Upgraded Stock: Finding the Right Fit
The adjustable stock allows for personalized fit, improving comfort and shooting consistency. Consider stocks from Magpul (CTR, MOE), or other reputable brands offering adjustable cheek rests and length of pull adjustments.
2. Enhanced Grip: A Better Hold
A more ergonomic pistol grip provides improved control and comfort during extended shooting sessions. Magpul's MOE grip is a popular and cost-effective choice, but many other options cater to various hand sizes and preferences.
3. Optics & Sights: Accurate Target Acquisition
Choosing the right optic is crucial. Red dot sights are excellent for close-to-medium range, while scopes are ideal for longer distances. Consider your shooting style and intended uses when selecting your optic. Properly zeroing your sights is crucial for consistent accuracy.
Conclusion: A Personalized Upgrade Path
Upgrading your MP15 Sport II is a journey of personalization. Prioritize the upgrades that best align with your shooting style, budget, and intended use. Always follow safe gun handling practices and consult with a qualified gunsmith if you have any questions or concerns during the upgrade process. Remember to check all applicable local, state, and federal regulations before modifying your firearm.
