The Mossberg 500 is a popular and versatile pump-action shotgun, used for various purposes such as hunting, self-defense, and sports shooting. Despite its robust design, disassembling the Mossberg 500 is a relatively simple process. In this article, we will provide a step-by-step guide on how to break down a Mossberg 500.
Disassembly and Maintenance: Why You Need to Do It
Regular disassembly and cleaning of your Mossberg 500 are crucial to maintain its performance and longevity. Here are some reasons why:
• Improved reliability: Disassembling your Mossberg 500 helps you identify and address any malfunctions or blockages.
• Extended life expectancy: Regular cleaning and lubrication reduce the risk of corrosion and wear and tear.
• Easy inspection and maintenance: Breaking down the shotgun allows you to inspect and maintain moving parts, ensuring optimal functioning.
• Cost-effective: Avoiding premature parts failure due to neglect saves you money in the long run.
Breaking Down a Mossberg 500: The Process
Follow these steps to disassemble your Mossberg 500:
- Field Strip
Step 1.1: Remove the Safety
First, release the safety by flipping it forward. This ensures the action is fully unlocked, allowing for easier disassembly.
Step 1.2: Extract the Cartridge
With the safety off, cycle the bolt to extract a shell casing. This removes the rounds from the chamber, and you’re now ready for disassembly.
- Pump Removal
Step 2.1: Lift the Shell Ejector
Flip the shell ejector downward, allowing you to withdraw the pump.
Step 2.2: Pull Out the Pump
Gently pull the pump forward and away from the receiver. It’s a simple and smooth operation, but be gentle to avoid damaging the O-ring.
Step 3.1: Release the Gas System
For optimal breakdown, release the gas system by pressing the release tab located on the side of the receiver.
Step 3.2: Remove the Magazine Cap
Twist the magazine cap counterclockwise and remove it from the magazine tube.
- Magazine Removal
Step 4.1: Withdraw the Magazine
Pull the magazine out from the receiver by grabbing it firmly and lifting it forward.
Step 4.2: Release the Magazine Tube Nut
You’ll find a small screw on the end of the magazine tube. Remove it by unscrewing the nut, then pull out the tube from the receiver.
- Final Disassembly
Step 5.1: Remove the Follower and Spring
Using your finger or a suitable tool, push the follower back through the magazine tube. Next, lift it out from the tube.
Step 5.2: Remove the Remaining Components
Take out the pump retaining pin, extractor rod, and the pump-to-receiver retaining clip. Be careful not to misplace these small parts.
- Cleaning and Inspecting
Use your choice of cleaning agents, cotton swabs, and other tools to clean all removed parts. Pay particular attention to areas around moving components, as buildup and dirt can lead to premature failure.
Reassembly Tips
Reassembly is often more challenging than disassembly. To simplify the process:
• Ensure parts are clean and free of debris
• Assemble in a consistent sequence
• Gently push parts back into position
• Reinstate the magazine cap, pump, and other parts in reverse order of removal
