Common Mossberg SA-20 Issues and Troubleshooting
This section breaks down frequently reported problems with the Mossberg SA-20, offering practical advice for resolving them. Remember, always prioritize safety when handling firearms. If you're uncomfortable performing any of these troubleshooting steps, consult a qualified gunsmith.
1. Failure to Feed/Eject
This is perhaps the most common complaint among SA-20 owners. Failures to feed or eject can stem from several sources:
- Ammunition Issues: Using low-quality, improperly loaded, or damaged ammunition is a leading cause. Try different brands and types of shells to see if that resolves the problem. Check for any visible damage to the shells themselves.
- Magazines: Worn or damaged magazines can cause feeding problems. Inspect your magazines for any signs of wear, damage, or debris. Cleaning and lubricating the magazine is crucial. Consider purchasing a new magazine if problems persist.
- Gas System: The SA-20's gas system needs to be clean and properly lubricated. Buildup of carbon and fouling can impede its operation. Regular cleaning and lubrication are paramount.
- Bolt Issues: A dirty or damaged bolt can also interfere with feeding and ejection. Thoroughly clean and inspect the bolt for any signs of wear or damage.
2. Jams
Jams, while frustrating, are often manageable. The most likely causes include:
- Overly Dirty Gun: A lack of regular cleaning contributes to malfunctions. A build-up of residue can interfere with the smooth operation of the action.
- Improperly Lubricated Parts: Insufficient lubrication leads to increased friction and potential jams. Regularly lubricate moving parts with a high-quality gun oil.
- Defective Parts: In rare cases, a defective part might be the culprit. This may require professional assessment and replacement.
3. Light Primer Strikes
This issue points to a problem with the firing pin or hammer.
- Weak Firing Pin Spring: A worn-out firing pin spring might not deliver enough force to reliably ignite the primer. This requires replacement.
- Dirty Firing Pin: A dirty firing pin can also impede reliable ignition. Cleaning is essential.
- Improperly Adjusted Trigger Mechanism: In rare instances, adjustments to the trigger mechanism could impact firing pin engagement. This requires expertise.
4. Poor Accuracy
While accuracy is subjective and depends on factors like ammunition, shooting technique, and sighting, problems can arise from:
- Improper Sighting: Ensure your sights are properly aligned.
- Improper Stock Fit: A stock that doesn't fit well can affect your accuracy.
- Ammunition: Test different ammunition types to find what your SA-20 shoots best.
Prevention is Key: Regular Maintenance
Consistent cleaning and lubrication are vital for preventing many of the problems listed above. Consult your owner's manual for specific cleaning instructions. Regular inspection for wear and tear can also prevent issues from developing.
