The Smith & Wesson M&P Sport II is a popular AR-15 platform rifle, known for its affordability and reliability. However, like any firearm, there's always room for improvement. This guide explores essential and optional upgrades for your M&P Sport II, focusing on enhancing accuracy, reliability, and overall shooting experience. We'll delve into practical improvements, avoiding unnecessary modifications that might compromise the rifle's integrity.
Essential Upgrades for Your M&P Sport II
These upgrades are highly recommended for improving the performance and reliability of your M&P Sport II. They address common areas of concern for stock models and offer noticeable improvements.
1. Upgraded Trigger: The Foundation of Accuracy
The stock trigger on the M&P Sport II is functional, but far from ideal for precision shooting. A significant upgrade involves replacing it with an enhanced trigger group. This improves trigger pull weight, reduces creep, and provides a crisper break, all leading to improved accuracy and shot control. Look for reputable brands offering drop-in trigger groups designed for AR-15 platforms, ensuring compatibility with your specific model. Consider factors like trigger pull weight and overall feel to select the best option for your needs.
2. Enhanced Handguard: Improved Ergonomics and Cooling
The standard handguard on the M&P Sport II can get hot during extended shooting sessions. Moreover, its limited rail space restricts the attachment of accessories. Upgrading to a free-floating handguard with M-LOK or KeyMod attachment points solves both problems. These handguards provide better heat dissipation and offer ample space to add accessories such as lights, lasers, or vertical grips, enhancing ergonomics and customization. Consider the material (aluminum or polymer) and length to choose the best fit for your rifle and shooting style.
3. Reliable Optics: Enhancing Accuracy and Situational Awareness
Proper sighting is crucial for accuracy. While the M&P Sport II often comes with iron sights, an upgrade to a quality optic is a significant improvement. The choice of optic depends heavily on intended use. For close to medium range shooting, a red dot sight offers speed and ease of use. For longer-range engagements, consider a low-power variable optic (LPVO) or a magnified optic with a reticle suited to your needs. Choosing a robust optic with proper mounting is paramount for reliable and accurate shooting.
Optional Upgrades to Consider
These upgrades offer further customization and improvements based on individual needs and preferences.
1. Enhanced Bolt Carrier Group (BCG): Reliability and Durability
While the factory BCG is generally reliable, an upgraded BCG made from higher-quality materials (like Nickel Boron or Carpenter 158 steel) can increase durability and longevity, especially in harsh conditions. This is a worthwhile investment for those who frequently shoot their rifles or use them in demanding environments.
2. Improved Buffer System: Reduced Recoil and Smoother Cycling
Experimenting with different buffer weights can fine-tune the rifle's recoil characteristics and cycling. A heavier buffer can reduce felt recoil, while a lighter buffer might be beneficial for suppressed use or specific ammunition types. It's essential to consult resources and select the appropriate buffer weight for your specific setup and needs.
3. Adjustable Gas Block: Fine-tuning the System
An adjustable gas block provides greater control over the rifle's gas system, allowing for customization based on ammunition type, suppressor use, or environmental conditions. It enables tuning for optimal reliability and reduced recoil. However, installation requires a moderate level of mechanical aptitude.
Conclusion: A Personalized Approach to Upgrading
Choosing the right upgrades for your M&P Sport II depends on your individual needs and shooting style. Prioritize the essential upgrades first, focusing on trigger, handguard, and optic improvements. Then, consider the optional upgrades based on your budget and shooting goals. Remember always to adhere to all safety regulations when working on your firearm, and consult with experienced gunsmiths or professionals if needed. This guide serves as a starting point for enhancing your M&P Sport II; responsible firearm ownership involves continuous learning and adaptation.
