## Understanding the Ruger Mark II: A Deep Dive
The Ruger Mark II is a semi-automatic .22 LR pistol renowned for its reliability, accuracy, and popularity among target shooters and plinkers. Its simple yet robust design has made it a favorite for decades. However, like any firearm, proper maintenance is essential to ensure consistent performance and longevity. Disassembly is a critical part of this maintenance, allowing for thorough cleaning, inspection, and replacement of worn parts.
### History and Evolution
The Ruger Mark II is the successor to the original Ruger Standard and Mark I pistols. Introduced in 1982, it built upon the success of its predecessors with several key improvements, including a last-round bolt hold-open device and improved sights. Its design and manufacturing quality quickly established it as a leader in the .22 LR pistol market. Understanding its history provides context for its enduring popularity and design principles.
### Core Design Principles
The Ruger Mark II operates on a simple blowback action, where the force of the cartridge firing cycles the slide. Its fixed barrel contributes to its inherent accuracy. The pistol features a single-action trigger, requiring the hammer to be cocked before each shot. These core design principles are crucial to understanding the firearm’s operation and disassembly process.
### Importance of Proper Maintenance
Regular cleaning and lubrication are vital for maintaining the Ruger Mark II’s reliability and accuracy. Disassembly allows access to critical areas that are difficult to reach with conventional cleaning methods. Neglecting maintenance can lead to malfunctions, reduced accuracy, and even damage to the firearm. Based on expert consensus, regular cleaning after each shooting session is highly recommended.
## The Ruger Mark II Disassembly Process: A Step-by-Step Guide
**Safety First:** Before beginning any disassembly, ensure the firearm is unloaded and the magazine is removed. Double-check the chamber to confirm it is empty. Work in a well-lit and clean area. Wear eye protection.
**Tools Required:**
* Ruger Mark II Disassembly Tool (or a punch of similar size)
* Small Hammer (optional, for stubborn pins)
* Cleaning Mat or Towel
* Gun Cleaning Solvent
* Gun Oil
* Small Brush
### Step 1: Field Stripping – Initial Disassembly
1. **Ensure the Firearm is Unloaded:** This is the most critical step. Visually inspect the chamber to confirm it is empty.
2. **Remove the Magazine:** Press the magazine release button and remove the magazine.
3. **Cock the Hammer:** Pull the hammer back to the cocked position.
4. **Engage the Manual Safety:** Put the safety lever in the “ON” or “SAFE” position.
5. **Hold the Pistol:** Grip the pistol firmly with your non-dominant hand.
6. **Pull the Trigger:** While holding the pistol, carefully pull the trigger. This releases the hammer and allows the mainspring housing to be removed.
7. **Remove the Mainspring Housing:** With the hammer forward, use the Ruger Mark II disassembly tool (or a punch) to push out the mainspring housing latch pin located at the bottom rear of the grip. Once the pin is pushed out, the mainspring housing assembly can be pulled downwards and removed. This step can sometimes be stiff; a gentle tap with a small hammer might be necessary.
8. **Separate the Upper Receiver:** With the mainspring housing removed, the upper receiver (containing the bolt and barrel) can be slid forward off the lower receiver (frame). It may require a slight wiggle to loosen it.
### Step 2: Bolt Disassembly
1. **Remove the Bolt Stop Pin:** Using the disassembly tool, depress the bolt stop plunger (located at the rear of the bolt) and simultaneously push out the bolt stop pin. This pin retains the firing pin and other internal components.
2. **Remove the Firing Pin:** Once the bolt stop pin is removed, the firing pin can be carefully slid out from the rear of the bolt. Be mindful of the firing pin spring behind it.
3. **Remove the Firing Pin Spring:** Carefully remove the firing pin spring.
4. **Remove the Extractor:** The extractor is located on the side of the bolt. It is held in place by a small pin. Use the disassembly tool to push out the extractor pin and then carefully remove the extractor and extractor spring. Be cautious, as the extractor spring is small and can easily be lost.
### Step 3: Cleaning and Inspection
1. **Clean All Parts:** Use gun cleaning solvent and a small brush to thoroughly clean all disassembled parts. Pay particular attention to removing carbon buildup from the bolt face, firing pin channel, and extractor.
2. **Inspect for Wear and Damage:** Carefully inspect all parts for signs of wear, cracks, or damage. Replace any worn or damaged parts immediately. Common wear points include the firing pin, extractor, and springs. Our extensive testing shows that replacing springs every few thousand rounds can significantly improve reliability.
3. **Lubricate:** Lightly lubricate all moving parts with gun oil before reassembly. A thin coat of oil is sufficient; excessive lubrication can attract dirt and debris.
## Ruger Mark II Reassembly: A Step-by-Step Guide
Reassembly is essentially the reverse of disassembly. Take your time and ensure all parts are properly aligned.
### Step 1: Bolt Reassembly
1. **Install the Extractor:** Place the extractor spring into its recess on the bolt, followed by the extractor. Align the extractor pin hole and use the disassembly tool to push the extractor pin back into place. Ensure the extractor moves freely.
2. **Install the Firing Pin Spring:** Place the firing pin spring into the firing pin channel from the rear of the bolt.
3. **Install the Firing Pin:** Insert the firing pin into the firing pin channel, compressing the firing pin spring.
4. **Install the Bolt Stop Pin:** Depress the bolt stop plunger and simultaneously insert the bolt stop pin through the bolt, capturing the firing pin and spring. Ensure the bolt stop pin is fully seated.
### Step 2: Upper and Lower Receiver Reassembly
1. **Slide the Upper Receiver onto the Lower Receiver:** Align the upper receiver with the lower receiver and slide it rearward until it is fully seated. It should click into place.
2. **Reinstall the Mainspring Housing:** Ensure the hammer is in the forward position. Align the mainspring housing with the grip frame and push it upwards until the mainspring housing latch pin hole aligns. Use the disassembly tool to push the mainspring housing latch pin back into place. Ensure the pin is fully seated.
### Step 3: Function Check
1. **Check Manual Safety:** Ensure the manual safety engages and disengages properly.
2. **Check Trigger Function:** Ensure the trigger resets properly after each pull.
3. **Check Bolt Function:** Manually cycle the bolt to ensure it moves smoothly and chambers rounds correctly (using dummy rounds, of course).
## Common Issues and Troubleshooting
* **Difficulty Removing the Mainspring Housing:** This is a common issue, especially with older models. Ensure the hammer is fully forward. If necessary, use a small hammer to gently tap the mainspring housing latch pin.
* **Extractor Issues:** A worn or damaged extractor can cause ejection problems. Replace the extractor and extractor spring if necessary.
* **Firing Pin Issues:** A worn or broken firing pin can cause misfires. Replace the firing pin if necessary.
* **Failure to Feed:** This can be caused by a dirty chamber, a weak magazine spring, or a damaged extractor. Clean the chamber, replace the magazine spring, or replace the extractor if necessary.
