## Step-by-Step Guide to Disassemble Ruger Mark IV 22/45 Bolt
**Safety First:** Before beginning any disassembly, ensure the pistol is unloaded and the magazine is removed. Double-check the chamber to confirm it is empty. Work in a well-lit and clean area.
1. **Remove the Bolt from the Pistol:**
* Refer to your Ruger Mark IV 22/45 owner’s manual for instructions on removing the bolt from the pistol. Typically, this involves field stripping the pistol and then removing the bolt assembly.
2. **Locate the Extractor Pin:**
* The extractor pin is a small pin located on the side of the bolt, holding the extractor and extractor plunger in place.
3. **Push Out the Extractor Pin:**
* Using a small punch and hammer, gently tap the extractor pin out of the bolt. Support the bolt on a solid surface while tapping.
* **Caution:** Be careful not to lose the extractor plunger and spring, as they are under spring tension and may fly out when the pin is removed. Cover the area with your hand to prevent this.
4. **Remove the Extractor, Extractor Plunger, and Spring:**
* Once the extractor pin is removed, carefully remove the extractor, extractor plunger, and extractor spring from the bolt. Note the orientation of these parts for reassembly.
5. **Remove the Firing Pin Retaining Pin:**
* Locate the firing pin retaining pin, which secures the firing pin in the bolt. This pin is usually located at the rear of the bolt.
6. **Push Out the Firing Pin Retaining Pin:**
* Using a small punch and hammer, gently tap the firing pin retaining pin out of the bolt. Support the bolt on a solid surface while tapping.
* **Caution:** The firing pin is under spring tension. Hold your hand over the firing pin as you remove the retaining pin to prevent it from launching out.
7. **Remove the Firing Pin and Firing Pin Spring:**
* Carefully remove the firing pin and firing pin spring from the bolt. Note the orientation of these parts for reassembly.
8. **Disassembly Complete:**
* The bolt is now fully disassembled. You should have the following parts separated: bolt body, extractor, extractor plunger, extractor spring, firing pin, and firing pin spring.
## Cleaning and Inspecting the Bolt Components
After disassembling the Ruger Mark IV 22/45 bolt, thoroughly clean and inspect each component. This step is crucial for maintaining the pistol’s reliability and performance.
1. **Cleaning:**
* Use a cleaning solvent and cleaning patches to remove carbon buildup, fouling, and residue from all parts. Pay particular attention to the firing pin channel, extractor, and bolt face. A small brush can be helpful for scrubbing hard-to-reach areas. Ensure all solvent is removed before proceeding to lubrication.
2. **Inspection:**
* **Bolt Body:** Check for cracks, dents, or excessive wear. Pay close attention to the bolt face and the area around the firing pin hole.
* **Firing Pin:** Inspect the firing pin tip for damage or wear. A worn or broken firing pin can cause misfires.
* **Firing Pin Spring:** Check the spring for kinks, breaks, or loss of tension. A weak spring can cause light strikes.
* **Extractor:** Examine the extractor claw for chips, cracks, or wear. A damaged extractor can cause failures to extract.
* **Extractor Plunger and Spring:** Inspect the plunger for damage and the spring for loss of tension. These parts are essential for proper extractor function.
3. **Lubrication:**
* Apply a light coat of gun oil or grease to all moving parts. Focus on the firing pin channel, extractor, and bolt rails. Avoid over-lubricating, as excess oil can attract dirt and debris. Experts recommend using a high-quality lubricant specifically designed for firearms.
## Reassembling the Ruger Mark IV 22/45 Bolt
Reassembly is the reverse of the disassembly process. Follow these steps carefully, ensuring all parts are properly aligned and seated.
1. **Install the Firing Pin and Firing Pin Spring:**
* Insert the firing pin and firing pin spring into the bolt. Ensure the firing pin is oriented correctly.
2. **Install the Firing Pin Retaining Pin:**
* Align the firing pin retaining pin hole in the bolt with the firing pin. Gently tap the retaining pin into place using a small punch and hammer.
3. **Install the Extractor, Extractor Plunger, and Spring:**
* Insert the extractor spring, extractor plunger, and extractor into the bolt. Ensure the extractor claw is facing the correct direction.
4. **Install the Extractor Pin:**
* Align the extractor pin hole in the bolt with the extractor, plunger, and spring. Gently tap the extractor pin into place using a small punch and hammer.
5. **Verify Proper Function:**
* After reassembly, manually cycle the bolt to ensure all parts are functioning correctly. Check that the firing pin moves freely and the extractor grips the rim of a cartridge casing (use an empty casing for testing).
## Troubleshooting Common Issues During Disassembly and Reassembly
Even with careful attention, you may encounter some common issues during disassembly and reassembly. Here are some troubleshooting tips:
* **Difficulty Removing the Extractor Pin:**
* Ensure you are using the correct size punch. Apply penetrating oil to the pin and let it sit for a few minutes before attempting to remove it. If the pin is still stuck, try tapping it from the opposite side.
* **Difficulty Removing the Firing Pin Retaining Pin:**
* Make sure the firing pin is fully forward. Applying slight pressure to the firing pin while tapping the pin can help. If the pin is still stuck, try using a smaller punch.
* **Difficulty Installing the Extractor Pin:**
* Ensure the extractor, plunger, and spring are properly aligned. Use a slave pin (a pin slightly smaller than the extractor pin) to hold the parts in place while you insert the extractor pin.
* **Firing Pin Not Moving Freely:**
* Check for obstructions in the firing pin channel. Clean the channel thoroughly with a brush and solvent. Ensure the firing pin spring is properly seated.
* **Extractor Not Gripping Cartridge Casings:**
* Inspect the extractor claw for damage. Replace the extractor if it is worn or broken. Ensure the extractor spring and plunger are functioning correctly.
## Safety Precautions and Best Practices
Always prioritize safety when working with firearms. Here are some essential safety precautions and best practices to follow:
* **Always Treat Every Firearm as if It Is Loaded:**
* Never assume a firearm is unloaded. Always double-check the chamber before handling it.
* **Keep the Muzzle Pointed in a Safe Direction:**
* Never point the muzzle at anything you are not willing to destroy.
* **Wear Safety Glasses:**
* Protect your eyes from flying debris or springs.
* **Work in a Well-Lit and Clean Area:**
* Ensure you have adequate lighting and a clean workspace to prevent accidents.
* **Use the Correct Tools:**
* Using the wrong tools can damage the firearm or cause injury.
