Common Mossberg 930 SPX Issues and Their Solutions

This section focuses on frequently reported problems with the Mossberg 930 SPX. We'll break down each issue, explaining potential causes and providing effective solutions. Remember, always prioritize safety when working with firearms. If you're uncomfortable performing any maintenance or repair, consult a qualified gunsmith.

1. Failure to Feed/Eject

This is arguably the most common Mossberg 930 SPX problem. It can manifest in several ways: the shotgun failing to pick up a shell from the magazine, shells jamming in the feed ramp, or spent casings not ejecting properly.

  • Possible Causes:

    • Dirty or damaged action: Buildup of dirt, debris, or lubricant can hinder the smooth operation of the action. Damage to the bolt or feed ramp can also cause feeding or ejection issues.
    • Improper ammunition: Using ammunition that's too light or too heavily loaded can disrupt the cycling process. Low-quality ammunition is a frequent culprit.
    • Weak gas system: Insufficient gas pressure may not provide enough power to cycle the action reliably, especially with lighter loads.
    • Bent or damaged extractor/ejector: These components are vital for properly extracting spent shells and ejecting them from the receiver.
  • Solutions:

    1. Clean the action thoroughly: Dismantle the shotgun and meticulously clean all parts of the action, paying close attention to the bolt, feed ramp, and gas system.
    2. Inspect for damage: Carefully examine the bolt, extractor, ejector, and feed ramp for any signs of bending, breakage, or damage. Replace any damaged parts.
    3. Use appropriate ammunition: Stick to recommended ammunition loads as specified in your Mossberg 930 SPX manual. Avoid using excessively light or heavy loads.
    4. Adjust gas system (if necessary): Some Mossberg 930 SPX models have adjustable gas systems. Adjusting the gas setting might solve feeding or ejection problems caused by insufficient gas pressure. Consult your owner's manual for proper adjustment procedures.

2. Light Strike Issues

A light strike occurs when the firing pin does not hit the primer with enough force to detonate the cartridge.

  • Possible Causes:

    • Weak firing pin spring: Over time, the firing pin spring can weaken, reducing the force of the firing pin strike.
    • Dirty firing pin: Dirt or debris can impede the firing pin's movement.
    • Improper ammunition: Ammunition with hard primers might require more force for detonation.
  • Solutions:

    1. Clean the firing pin: Thoroughly clean the firing pin and its channel.
    2. Check the firing pin spring: Inspect the firing pin spring for wear or weakness. Replace it if necessary.
    3. Use high-quality ammunition: Employ reliable, high-quality ammunition known for consistent primer ignition.

3. Magazine Tube Problems

Issues with the magazine tube can affect feeding reliability.

  • Possible Causes:

    • Bent or damaged magazine tube: A damaged magazine tube can interfere with smooth shell feeding.
    • Loose magazine cap: A loose magazine cap can cause shells to fall out or feed improperly.
  • Solutions:

    1. Inspect the magazine tube: Carefully check the magazine tube for any bends, dents, or obstructions. Straighten any bends or replace the tube if necessary.
    2. Tighten the magazine cap: Ensure that the magazine cap is securely fastened. If it's stripped or damaged, replace it.

4. Overall Reliability Problems

Sometimes, the Mossberg 930 SPX exhibits general unreliability, which can be a combination of several factors.

  • Possible Causes:

    • Accumulated fouling: Regular cleaning is crucial. Significant fouling can affect the entire operation.
    • Improper maintenance: Neglecting regular maintenance and cleaning will inevitably lead to problems.
    • Use of unsuitable ammunition: Sticking to the manufacturer's recommended ammunition is vital for optimal performance.
  • Solutions:

    1. Thorough cleaning: Disassemble and clean the weapon completely. Pay attention to all the details. Use a good quality gun cleaning kit and appropriate solvent.
    2. Consistent lubrication: Use a good quality gun lubricant on moving parts to reduce friction and ensure smooth operation.
    3. Adherence to recommended practices: Always adhere to the manufacturer's recommendations for maintenance, ammunition, and operation.

Preventive Maintenance for Your Mossberg 930 SPX

Regular maintenance is crucial for preventing problems and extending the lifespan of your Mossberg 930 SPX. Here's a basic maintenance schedule:

  • After each shooting session: Clean the bore and action.
  • Monthly: Perform a more thorough cleaning, disassembling the action for a deeper clean.
  • Annually: Consider a professional inspection and servicing to ensure your shotgun is in optimal condition.

By addressing these common problems promptly and implementing a proactive maintenance schedule, you can significantly improve the reliability and longevity of your Mossberg 930 SPX. Remember safety is paramount; if you are ever unsure about performing any maintenance, consult a qualified gunsmith.
