The Mossberg 500 is a popular and reliable shotgun, prized for its simplicity and ease of maintenance. Knowing how to field strip your Mossberg 500 is crucial for cleaning, inspection, and ensuring its continued safe and effective operation. This guide will walk you through the process step-by-step, providing clear instructions and safety precautions. Always ensure the firearm is unloaded and the action is open before beginning any disassembly.
Safety First: Essential Precautions
Before you even think about taking apart your Mossberg 500, prioritize safety:
- Unloaded Weapon: Absolutely confirm the shotgun is unloaded. Visually inspect the chamber and magazine tube.
- Open Action: Keep the action open throughout the disassembly process. This prevents accidental discharge.
- Safe Environment: Work in a clean, well-lit area with a soft surface to prevent damage to your firearm.
- Tools: Gather the necessary tools beforehand. You'll primarily need a screwdriver (type depends on your model; check your manual), and potentially a punch or other small tool for stubborn pins.
- Manual: Refer to your Mossberg 500 owner's manual for specific instructions and diagrams relevant to your model. This guide provides general instructions, but variations may exist across different Mossberg 500 models.
Step-by-Step Disassembly of your Mossberg 500
This guide outlines the basic field stripping process. Specific steps might vary slightly depending on your model. Always prioritize safety and consult your owner's manual if you have any doubts.
1. Removing the Forend
- With the action open, push the forend release button (usually located on the underside of the receiver).
- Slide the forend forward and off the magazine tube.
2. Removing the Barrel
- Locate the Barrel Nut: The barrel nut is located at the front of the receiver where the barrel meets the receiver.
- Unscrew the Barrel Nut: Use a wrench (often included with the shotgun) to carefully unscrew the barrel nut. Some models require a specific tool; consult your owner's manual.
- Remove the Barrel: Once the barrel nut is removed, the barrel can be carefully pulled forward and away from the receiver.
3. Removing the Bolt and Bolt Handle
- Remove the Bolt Handle: Depress the bolt handle release and pull the bolt handle straight back. This may require some force, but avoid applying excessive pressure.
- Remove the Bolt: With the bolt handle removed, the bolt should slide out of the receiver.
4. Disassembling the Trigger Group (Advanced – Consult Your Manual)
Disassembling the trigger group is generally unnecessary for basic cleaning and maintenance. If you need to disassemble the trigger group, consult your Mossberg 500 owner's manual. Improper reassembly can render the firearm unsafe and inoperable. This step requires more advanced knowledge and tools.
Reassembly: Reverse the Process
Reassembly is the reverse of disassembly. Carefully align all parts and ensure they are properly seated before proceeding to the next step. Again, consult your owner's manual for detailed instructions and diagrams.
Cleaning and Maintenance
Once disassembled, clean your Mossberg 500 thoroughly using a suitable gun cleaning kit and solvent. Pay particular attention to the barrel, chamber, and bolt. After cleaning, reassemble the firearm and lubricate moving parts with a suitable gun oil.
When to Seek Professional Help
If you encounter any difficulties during disassembly or reassembly, or if you are unsure about any step, it's always best to seek the assistance of a qualified gunsmith. Improper handling or reassembly can lead to malfunctions or even injury.
This comprehensive guide offers a detailed overview of how to take apart your Mossberg 500. Remember that safety is paramount, so always prioritize safety procedures before, during and after handling your firearm. Always refer to your owner's manual for model-specific instructions and illustrations.
