6. **Once the mainspring housing is removed, carefully separate the mainspring strut and mainspring.**
### Step 2: Removing the Bolt
With the mainspring housing removed, you can now remove the bolt.
1. **Pull the bolt fully to the rear.**
2. **Lift the bolt up and out of the receiver.** It should slide out relatively easily. If it doesn’t, gently wiggle it back and forth while pulling upward.
### Step 3: Removing the Trigger Group
The trigger group is held in place by two pins. You will need a punch and hammer for this step.
1. **Using a punch and hammer, gently tap out the two pins that hold the trigger group in place.** Work from left to right, as the pins are often slightly tapered.
2. **Once the pins are removed, the trigger group should slide out of the receiver.**
### Step 4: Magazine Disassembly (Optional but Recommended)
Cleaning the magazine is an important part of maintaining your Ruger Mark II. While not strictly necessary for every cleaning, it’s recommended periodically.
1. **Using a magazine disassembly tool (or a small punch), depress the magazine follower slightly.** This will relieve tension on the magazine floorplate.
2. **Slide the magazine floorplate forward and off the magazine body.** Be careful, as the magazine spring is under tension.
3. **Carefully remove the magazine spring and follower from the magazine body.**
### Step 5: Further Disassembly (Advanced – Proceed with Caution)
Further disassembly of the bolt and trigger group is possible but generally not necessary for routine cleaning. These steps require more specialized knowledge and tools. Incorrect reassembly can lead to malfunctions. **If you are not comfortable with this level of disassembly, it’s best to leave these parts assembled.** However, for those with experience:
* **Bolt Disassembly:** The firing pin and extractor can be removed from the bolt with the appropriate punches and tools. Consult a detailed schematic or video guide before attempting this.
* **Trigger Group Disassembly:** The trigger group contains numerous small parts and springs. Disassembly should only be attempted by experienced gunsmiths or those with a thorough understanding of the mechanism.
