The Mossberg 500 shotgun's popularity stems from its robust design, affordability, and ease of customization. One key component often requiring attention or replacement is the action slide tube. This guide delves into understanding its function, common issues, and how to maintain or replace it.
Understanding the Mossberg 500 Action Slide Tube
The action slide tube, sometimes referred to as the action slide bar or simply the slide tube, is a crucial part of the Mossberg 500's pump-action mechanism. Located beneath the barrel, it interacts with the action bars to cycle the shotgun's action, allowing for smooth loading and ejection of shells. Its smooth operation is vital for reliable functionality. A malfunctioning or damaged action slide tube can lead to misfires, jams, or even unsafe operation.
Key Functions of the Action Slide Tube:
- Shell Ejection: The tube facilitates the ejection of spent shell casings.
- Shell Loading: It plays a key role in smoothly chambering a fresh round.
- Action Cycling: The tube's interaction with the action bars allows for the consistent cycling of the pump action.
Common Problems and Troubleshooting
While generally durable, the action slide tube can encounter problems over time, especially with heavy use or improper maintenance. Here are some common issues:
1. Jamming or Sticking:
- Cause: This is often due to dirt, debris, or buildup of residue within the tube or surrounding mechanism. Corrosion can also play a role.
- Solution: Thorough cleaning and lubrication are crucial. Disassemble the shotgun (following manufacturer instructions carefully), clean the tube thoroughly, and apply a high-quality gun lubricant.
2. Damage or Wear:
- Cause: Excessive use, dropping the firearm, or impacts can damage the tube. Wear can manifest as scratches or significant deformation.
- Solution: If the damage is minor (superficial scratches), cleaning and lubrication might suffice. However, significant damage typically necessitates replacement.
3. Loose or Wobbly Action:
- Cause: Wear on the tube's contact points or loose screws can lead to a loose or wobbly action.
- Solution: Check for loose screws and tighten them securely. If the problem persists, the tube might need replacing.
Replacing the Mossberg 500 Action Slide Tube
Replacing the action slide tube requires some mechanical aptitude and familiarity with firearms disassembly. Always consult the Mossberg 500 owner's manual for detailed instructions and safety precautions before attempting any repairs or replacements. Improper handling can lead to injury or damage to the firearm.
Key Steps (General Overview - Consult Your Manual):
- Safe Unloading: Ensure the firearm is completely unloaded and the action is open.
- Disassembly: Follow the manufacturer's instructions to disassemble the shotgun, carefully removing components to access the action slide tube.
- Removal: Remove the old action slide tube.
- Installation: Install the new action slide tube, ensuring it is correctly seated and aligned.
- Reassembly: Carefully reassemble the shotgun, following the manufacturer's instructions in reverse order.
- Function Check: After reassembly, conduct a thorough function check to ensure smooth operation before using the firearm.
Maintaining Your Mossberg 500 Action Slide Tube
Regular maintenance is crucial to prevent problems and ensure the longevity of your Mossberg 500.
- Regular Cleaning: Clean the action slide tube regularly, removing any dirt, debris, or residue.
- Lubrication: Apply a high-quality gun lubricant to the tube and surrounding components after cleaning.
- Inspection: Periodically inspect the tube for any signs of wear, damage, or corrosion.
