This guide dives into common Mossberg 930 SPX problems, offering troubleshooting tips and solutions to help you keep your shotgun running smoothly. We'll cover everything from minor adjustments to more significant repairs, emphasizing safety throughout. Remember, always handle firearms responsibly and follow all safety procedures.
Common Mossberg 930 SPX Issues and How to Address Them
This section addresses some of the most frequently reported problems with the Mossberg 930 SPX.
1. Failure to Feed/Eject
This is perhaps the most common complaint among 930 SPX owners. Several factors can contribute to feeding and ejection problems:
-
Ammunition: Using low-quality, dirty, or improperly sized ammunition is a leading cause of feeding and ejection issues. Start by trying different brands and types of shells, ensuring they are compatible with your shotgun's specifications. Clean your ammunition before use if necessary.
-
Magazines: Inspect your magazine for any damage, debris, or wear. Bent or damaged feed lips can prevent smooth feeding. A dirty magazine can also hinder performance. Clean your magazine thoroughly, using a suitable cleaning solvent.
-
Bolt: A dirty or improperly lubricated bolt can lead to feeding problems. Disassemble the bolt (following Mossberg's instructions carefully) and clean it thoroughly. Use a high-quality gun lubricant, applying it sparingly to the moving parts.
-
Gas System: The gas system is crucial for the 930 SPX's operation. Accumulated dirt, carbon buildup, or damage to the gas system can severely impact reliability. Regular cleaning and maintenance of the gas system are essential.
2. Light Strikes/Misfires
Light strikes often result from:
-
Weak Recoil Spring: A worn-out recoil spring can fail to fully cycle the bolt, resulting in a light strike. Replacing the recoil spring is relatively straightforward and should be done if you suspect this is the issue.
-
Firing Pin Issues: Inspect the firing pin for damage or wear. A damaged or broken firing pin needs immediate replacement.
-
Ammunition Problems: As with feeding issues, poor-quality ammunition can contribute to misfires. Try different ammunition types.
3. Jamming
Jamming can stem from a multitude of factors, including those mentioned above. In addition:
-
Over-Lubrication: Too much lubricant can attract dirt and debris, leading to jams. Use lubricant sparingly.
-
Improper Cleaning: Improper cleaning or incomplete removal of cleaning solvents can cause malfunctions. Follow the manufacturer's cleaning instructions meticulously.
-
Broken Parts: In some cases, a broken part, such as a shell stop or extractor, might be responsible for the jamming. If you suspect a broken part, seek professional repair.
Maintaining Your Mossberg 930 SPX for Optimal Performance
Regular maintenance is paramount for preventing problems and ensuring reliable operation of your 930 SPX. This includes:
- Regular Cleaning: Clean your shotgun thoroughly after each use, paying particular attention to the gas system, bolt, and magazine.
- Lubrication: Use high-quality gun lubricant to keep moving parts well lubricated.
- Inspection: Regularly inspect your shotgun for any signs of wear or damage.
- Professional Service: If you're uncomfortable performing maintenance or repairs yourself, seek the services of a qualified gunsmith.
By addressing these common issues and following a consistent maintenance schedule, you can significantly extend the life of your Mossberg 930 SPX and ensure its reliable performance. Remember, safety is always paramount when handling firearms. If you are unsure about any maintenance or repair procedure, consult a qualified gunsmith.
