The Smith & Wesson M&P10 is a popular AR-15 platform rifle, lauded for its affordability and reliability. However, like any firearm, it's not without its potential issues. This guide delves into common problems reported by M&P10 owners, offering insights for troubleshooting and preventative maintenance. Understanding these potential pitfalls can help ensure a smoother, safer shooting experience.
Common S&W M&P10 Problems and Solutions
While generally reliable, several recurring issues have surfaced among M&P10 users. Let's examine some of the most frequently reported problems:
1. Gas Block Issues:
- Problem: Some users report issues with the gas block, including malfunctioning gas key screws loosening over time or the gas block itself becoming loose. This can lead to malfunctions, including failure to cycle properly or gas leaks.
- Solution: Regularly inspect the gas block screws for tightness. Consider using threadlocker (like Loctite) on these screws during assembly or reassembly to prevent loosening. If the gas block itself is loose, it may need to be re-seated or replaced. Proper torque is crucial; consult your owner's manual or a qualified gunsmith if unsure.
2. Bolt Carrier Group (BCG) Problems:
- Problem: Some users have reported issues with the BCG, including failures to extract or eject casings. This can be due to several factors, including improper lubrication, a dirty BCG, or wear and tear.
- Solution: Regular cleaning and lubrication of the BCG is crucial. Ensure you are using a high-quality gun lubricant and cleaning it thoroughly after each shooting session. Inspect the BCG for wear; excessive wear might require replacement.
3. Magazine Compatibility:
- Problem: Although the M&P10 generally works well with many standard AR-15 magazines, some users report issues with certain brands or types of magazines. This can manifest as feeding problems or failures to lock back on an empty magazine.
- Solution: Experiment with different brands of magazines to find one that consistently functions reliably in your specific rifle. Avoid cheap or off-brand magazines, as these are more prone to malfunctions.
4. Trigger Issues:
- Problem: While the factory trigger is generally considered acceptable for its price point, some users may find it less than ideal for precision shooting or prefer a different trigger pull.
- Solution: Many aftermarket trigger upgrades are available for the M&P10, offering improved performance and feel. However, ensure any modification is done by a qualified gunsmith or you have the necessary knowledge to avoid damaging the firearm.
5. Handguard Issues:
- Problem: Some users have reported issues with the handguard, such as looseness or difficulty installing accessories.
- Solution: Ensure the handguard is properly installed and tightened according to the manufacturer's instructions. If looseness persists, you may need to adjust the screws or consider a different handguard.
6. Optics Mounting:
- Problem: Occasionally, users have difficulties mounting optics, particularly with the use of certain mounting systems.
- Solution: Ensure you are using the correct mounting hardware and following the instructions carefully. Consider seeking advice from a gunsmith if you encounter persistent issues.
Preventative Maintenance is Key
Regular cleaning, lubrication, and inspection are vital for preventing many of these potential problems. A well-maintained M&P10 is far less likely to experience malfunctions. Always consult your owner's manual for specific maintenance instructions.
Conclusion
The Smith & Wesson M&P10 offers a solid platform at a competitive price. However, understanding potential issues and implementing proper preventative maintenance can significantly enhance reliability and user experience. Remember, responsible gun ownership includes thorough familiarization with your firearm and the ability to troubleshoot minor problems. For any significant issues, consulting a qualified gunsmith is always recommended.
