Step-by-Step Disassembly of the Stevens Model 520
This guide covers the general disassembly procedure. Specific variations might exist depending on the exact model and manufacturing date of your Stevens 520. Always consult your owner's manual for precise instructions specific to your firearm.
Step 1: Verify the Firearm is Unloaded
This is the most crucial step. Double-check to ensure the firearm is completely unloaded. Visually inspect the chamber and magazine (if applicable).
Step 2: Remove the Stock (if necessary)
Some maintenance tasks may require stock removal. This typically involves removing the screws securing the stock to the receiver. Consult your owner's manual for specific screw locations and procedures.
Step 3: Disassemble the Action
This is where the specific details vary most between different Stevens 520 models. The process generally involves removing various pins and screws securing the different components (bolt, trigger group, etc.) of the action. Detailed, illustrated instructions are essential here and can typically be found in well-regarded gunsmithing manuals or online forums dedicated to firearm repair and maintenance. Never proceed without clear and accurate visual guidance.
Step 4: Remove the Barrel
Once the action is disassembled, the barrel can usually be removed. This typically involves removing a retaining pin or screw. Be careful to note the position and orientation of all components as you disassemble them.
Step 5: Clean and Lubricate
Once all components are separated, thoroughly clean each part using appropriate solvents and gun oil. Pay particular attention to the bore, removing any residue or fouling.
Step 6: Reassembly
Reassembly is the reverse of disassembly. Carefully follow the steps in reverse order, ensuring all components are properly aligned and secured. Again, clear visual guides are essential.
Importance of Proper Cleaning and Maintenance
Regular cleaning and maintenance are crucial for maintaining the accuracy, reliability, and longevity of your Stevens Model 520. Neglecting this can lead to malfunctions and potentially damage your firearm. Regular cleaning intervals depend on the frequency of use but should generally occur after each shooting session.
