Tools You'll Need
Before you begin, gather the necessary tools. This will ensure a smooth and efficient disassembly process. You'll likely need:
- A properly sized screwdriver: The specific type will depend on your model's year and configuration. Check your firearm carefully before proceeding.
- A punch (optional): A small punch can be helpful for dislodging stubborn pins.
- A cleaning rod and patches: While not strictly part of the disassembly process, cleaning should always follow.
- A clean, well-lit workspace: This ensures you won't lose small parts.
- A gun cleaning mat: This will protect your firearm and your work surface.
- Cotton gloves (optional): To prevent fingerprints and oil from marring the finish.
Step-by-Step Disassembly of the Stevens Model 520
This guide will focus on the common procedures. Variations may exist depending on the specific year and configuration of your Stevens 520. Always reference your owner's manual if available.
1. Unload the Firearm
This is the most crucial step. Ensure the firearm is completely unloaded. Visually inspect the chamber and magazine to confirm there are no cartridges present. Point the firearm in a safe direction throughout the entire process.
2. Remove the Bolt
The bolt removal process may vary slightly depending on your 520's variant. Generally, you will need to:
- (If applicable) Remove the receiver cap: Some models have a cap on the rear of the receiver that needs to be removed.
- Depress the bolt release: Locate the bolt release and depress it to unlock the bolt.
- Carefully extract the bolt: Gently slide the bolt to the rear and remove it.
3. Remove the Trigger Group (if necessary for cleaning)
For a thorough cleaning, you might want to remove the trigger group. This will often involve:
- Locating the trigger group retaining pin(s): These pins hold the trigger group in place.
- Carefully driving out the pin(s): Use the punch (if necessary) to carefully remove the pins, ensuring you don't damage the surrounding components.
- Gently removing the trigger group: Once the pins are removed, the trigger group should come free.
4. Separate the Barrel from the Receiver (if necessary for deep cleaning)
This step is usually only required for thorough cleaning or repair and may involve removing additional pins or screws. Refer to your specific model's instructions for details.
Reassembly
Reassembly is essentially the reverse of disassembly. Take your time and ensure each part is correctly aligned before proceeding to the next step.
Maintenance and Cleaning
After disassembly, thoroughly clean each component using a suitable cleaning solvent and gun oil. Refer to your owner's manual or consult a qualified gunsmith for specific cleaning recommendations.
Conclusion
Disassembling your Stevens Model 520 is a manageable process if done carefully and methodically. This guide provides a general overview; however, always consult your owner's manual and prioritize safety. If you have any doubts or concerns, seek assistance from a qualified gunsmith. Remember, firearm safety is paramount.
