The Mossberg 930 SPX is a popular semi-automatic shotgun, favored by many for its reliability, versatility, and affordability. However, like any firearm, it's not immune to occasional malfunctions. This guide delves into common Mossberg 930 SPX problems, providing troubleshooting tips and potential solutions to help you keep your shotgun running smoothly.
Common Mossberg 930 SPX Issues and Their Solutions
Many issues stem from a lack of proper maintenance or ammunition incompatibility. Let's address some frequent problems:
1. Failure to Feed/Eject
This is perhaps the most common complaint among 930 SPX owners. Several factors can contribute:
-
Ammunition: Using low-quality, dirty, or improperly sized ammunition is a frequent culprit. Solution: Switch to high-quality, clean ammunition specifically designed for your shotgun's gauge. Experiment with different brands to find what works best. Avoid using reloaded ammunition unless you're confident in its quality and consistency.
-
Magazine Tube Issues: A dirty or damaged magazine tube can prevent smooth feeding. Solution: Thoroughly clean the magazine tube, ensuring no debris obstructs the shells' path. Check for any dents or damage that might interfere with shell feeding.
-
Bolt Issues: A dirty or improperly lubricated bolt can hinder its cycling. Solution: Disassemble the bolt, clean all parts meticulously, and re-lubricate with a high-quality gun oil.
-
Gas System: A dirty or malfunctioning gas system is another common cause. Solution: Clean the gas system thoroughly, removing any carbon buildup. Ensure the gas piston and related parts move freely. Refer to your owner's manual for detailed disassembly and cleaning instructions.
2. Jams and Misfires
Jams and misfires can stem from several sources:
-
Ammunition: As mentioned above, poor-quality ammunition is a major contributor.
-
Improper Cleaning: A lack of regular cleaning and maintenance can lead to jams. Solution: Establish a regular cleaning routine. Clean your shotgun after each use, especially if shooting in dirty conditions.
-
Extractor/Ejector Problems: Worn or damaged extractors and ejectors can prevent reliable cycling. Solution: Inspect the extractor and ejector for wear and tear. If damaged, consider replacement with factory parts.
-
Improper Functioning of the Bolt: As previously mentioned, the bolt plays a crucial role in the operation of the 930 SPX. Addressing bolt issues is essential.
3. Excessive Recoil
While recoil is expected, excessive recoil can indicate a problem.
-
Ammunition: Lighter loads generally produce less recoil. Solution: Try using lighter ammunition to reduce felt recoil.
-
Improper Stock Fit: If the stock doesn't fit you properly, it can amplify recoil. Solution: Consider adjusting the stock or purchasing an aftermarket stock to improve fit and comfort.
4. Inconsistent Cycling
This issue often relates to the points already discussed above (ammunition, gas system, and cleaning).
Solution: Methodically address each potential cause, starting with cleaning and ammunition, then moving to the gas system and finally checking the bolt and other internal parts.
Prevention and Maintenance for a Trouble-Free Mossberg 930 SPX
Regular maintenance is key to preventing problems:
- Clean your shotgun after every use. This is crucial for long-term reliability.
- Use high-quality ammunition. This minimizes the risk of malfunctions.
- Store your shotgun properly. Keep it in a safe, dry place.
- Lubricate your shotgun regularly. Use a quality gun oil.
