## Step-by-Step Ruger Mark II Disassembly Guide
**Safety First:** Always ensure the firearm is unloaded before beginning any disassembly process. Remove the magazine and visually inspect the chamber to confirm it is empty.
**Step 1: Field Stripping (Basic Disassembly)**
1. **Remove the Magazine:** Press the magazine release button located on the left side of the grip to remove the magazine.
2. **Clear the Chamber:** Pull the bolt back and visually inspect the chamber to ensure it is empty. Engage the safety.
3. **Mainspring Housing Latch:** Locate the mainspring housing latch at the rear of the grip frame. Pull it down and remove the mainspring housing. This can sometimes be stiff, requiring a bit of force. A soft-faced hammer can be used to gently tap it if needed.
4. **Separate the Upper and Lower Receivers:** With the mainspring housing removed, the upper receiver (containing the barrel and bolt) can be separated from the lower receiver (containing the trigger mechanism and grip frame). Slide the upper receiver forward and off the lower receiver.
**Step 2: Bolt Disassembly**
1. **Remove the Firing Pin Retaining Pin:** Using a punch, carefully drive out the firing pin retaining pin from the rear of the bolt. Support the bolt on a solid surface while doing this.
2. **Remove the Firing Pin and Extractor:** Once the retaining pin is removed, the firing pin and extractor can be removed from the bolt. Be careful, as these parts may be under spring tension.
3. **Remove the Extractor Plunger and Spring:** The extractor plunger and spring are located in a small recess on the side of the bolt. Use a small tool, such as a dental pick or small screwdriver, to carefully remove the plunger and spring.
**Step 3: Lower Receiver Disassembly (Advanced)**
*Note: Disassembling the lower receiver is more complex and generally only necessary for detailed cleaning or repair. Proceed with caution.*
1. **Remove the Sear Spring Plunger and Spring:** Locate the sear spring plunger and spring on the left side of the lower receiver. Use a small punch to depress the plunger and carefully remove the spring.
2. **Remove the Sear:** With the sear spring and plunger removed, the sear can be removed from the lower receiver. It may be necessary to use a small punch to gently tap it out.
3. **Remove the Hammer Strut and Hammer:** The hammer strut is located at the rear of the hammer. Use a punch to drive out the hammer pin and remove the hammer and hammer strut.
4. **Remove the Trigger and Trigger Plunger:** The trigger is held in place by a pin. Use a punch to drive out the trigger pin and remove the trigger and trigger plunger.
5. **Remove the Safety Lever:** The safety lever is located on the left side of the lower receiver. Use a punch to drive out the safety lever pin and remove the safety lever.
**Important Considerations:**
* **Take Pictures:** Before disassembling any complex mechanism, take pictures of each step. This will serve as a valuable reference during reassembly.
* **Keep Parts Organized:** Use small containers or a parts tray to keep the small parts organized and prevent loss.
* **Work in a Well-Lit Area:** Proper lighting is essential for seeing small parts and preventing mistakes.
* **Refer to a Diagram or Manual:** A detailed diagram or manual can be invaluable during disassembly and reassembly. The Ruger website often provides exploded diagrams.
