The Stevens Model 520 is a classic firearm, prized by collectors and shooters alike for its reliability and straightforward design. However, proper disassembly and cleaning are crucial for maintaining its functionality and longevity. This guide provides a detailed, step-by-step process for safely disassembling your Stevens Model 520. Always prioritize safety and ensure the firearm is unloaded before beginning any disassembly. Failure to do so can lead to serious injury or death.
Tools You'll Need
Before you begin, gather the necessary tools. You'll likely need:
- A soft, clean work surface: This will protect your firearm from scratches and provide a clear workspace.
- A gun cleaning mat: This helps to keep small parts organized and prevent loss.
- A screwdriver (likely a flathead): The specific size may vary depending on your model.
- A cleaning rod and patches: For cleaning the barrel after disassembly.
- Gun oil: For lubricating internal parts during reassembly.
- A container for small parts: To prevent losing any screws or pins.
Step-by-Step Disassembly of the Stevens Model 520
Note: Variations in the Model 520 may exist, so slight differences in the disassembly process might be encountered. This guide offers a general approach. Always consult your firearm's manual if available for specific instructions.
1. Safety Check: Double and Triple Check!
This is the most critical step. Remove the magazine, visually inspect the chamber, and then lock the action open (if possible) to ensure the firearm is completely unloaded. Point the firearm in a safe direction at all times.
2. Removing the Stock
This usually involves removing the stock screws located at the buttstock and possibly near the receiver. Carefully unscrew these, keeping track of their location and any washers or spacers. Once removed, gently separate the stock from the receiver.
3. Separating the Receiver and Barrel
This step can vary slightly depending on the specific Model 520 variant. Typically, you'll need to locate and remove a retaining pin or screw that connects the barrel to the receiver. This is usually found at the front of the receiver. Carefully remove the retaining pin or screw, and then gently separate the barrel from the receiver.
4. Disassembling the Bolt (If Necessary)
Depending on your cleaning needs, you may choose to further disassemble the bolt. This often involves removing a retaining pin or screw, allowing you to separate the bolt components. Handle these small parts with care to avoid damage or loss.
5. Cleaning the Components
Once disassembled, thoroughly clean each part using appropriate cleaning solvents and brushes. Pay particular attention to removing any residue or fouling from the barrel, chamber, and bolt. Lubricate all moving parts with a high-quality gun oil.
Reassembly
Reassembly is generally the reverse process of disassembly. Ensure each part is correctly aligned and seated before tightening screws or pins. Always refer to your firearm’s manual for specific reassembly instructions.
Important Considerations
- Photography: Before beginning, consider taking photos of each step of the disassembly process. This will be immensely helpful during reassembly.
- Manual: If you have the original owner's manual for your Stevens Model 520, consult it for detailed instructions and diagrams specific to your model.
- Gunsmith: If you are uncomfortable disassembling your firearm, seek the assistance of a qualified gunsmith. They possess the expertise and tools to perform this task safely and effectively.
This guide provides a general overview. Always prioritize safety and proceed cautiously. Improper disassembly can damage your firearm and may result in injury. Remember, firearm safety is paramount.
