## Step-by-Step Disassembly Guide
**Safety First:** Always ensure the firearm is unloaded before beginning any disassembly procedure. Double-check the chamber and magazine well. Wear safety glasses throughout the process.
1. **Remove the Magazine:** Press the magazine release button and remove the magazine.
2. **Ensure the Chamber is Empty:** Pull back the bolt and visually inspect the chamber to confirm it is empty. Release the bolt.
3. **Field Strip the Firearm:** Follow Ruger’s instructions for field stripping the Ruger Mark IV 22/45. This typically involves pushing a button at the rear of the receiver and separating the upper receiver from the lower receiver.
4. **Remove the Bolt Assembly:** With the upper receiver separated, the bolt assembly can be removed from the rear. Simply pull it out.
5. **Identify Bolt Components:** Familiarize yourself with the various components of the bolt, including the firing pin, extractor, ejector, and their respective retaining pins.
6. **Remove the Firing Pin Retaining Pin:** Using a small punch and hammer (if needed), gently push out the firing pin retaining pin. Support the bolt on a solid surface to prevent damage. Be careful, as the firing pin is under spring tension. Make sure that you are working in a safe area where the firing pin can not be lost.
7. **Remove the Firing Pin and Spring:** Once the retaining pin is removed, carefully remove the firing pin and its spring. Note the orientation of the spring for reassembly.
8. **Remove the Extractor Retaining Pin:** Locate the extractor retaining pin on the side of the bolt. Use a small punch to push it out. The extractor is also under spring tension, so be cautious.
9. **Remove the Extractor and Spring:** Once the retaining pin is removed, carefully remove the extractor and its spring. Note the orientation of the spring.
10. **Remove the Ejector (if applicable):** Some Ruger Mark IV 22/45 bolts have a separate ejector that can be removed. If present, it will typically be held in place by a small pin or friction. Carefully remove it.
## Cleaning the Bolt Components
After disassembling the bolt, thoroughly clean each component to remove carbon buildup and fouling. Use a quality cleaning solvent and appropriate brushes or patches.
* **Firing Pin:** Clean the firing pin with solvent and a small brush. Ensure the firing pin channel is free of debris.
* **Extractor:** Clean the extractor hook and surrounding area with solvent and a brush. Ensure the extractor spring is also clean.
* **Bolt Face:** Clean the bolt face with solvent and a patch. Remove any carbon buildup or residue.
* **Bolt Body:** Clean the exterior of the bolt body with solvent and a cloth. Remove any dirt or grime.
## Reassembling the Bolt
Reassembly is the reverse of the disassembly process. Pay close attention to the orientation of each component and ensure all retaining pins are properly seated.
1. **Install the Ejector (if applicable):** If your bolt has a separate ejector, install it first, ensuring it is properly seated.
2. **Install the Extractor and Spring:** Insert the extractor spring into its recess, followed by the extractor. Align the extractor and spring with the retaining pin hole and insert the retaining pin. Ensure the pin is fully seated.
3. **Install the Firing Pin and Spring:** Insert the firing pin spring into its recess, followed by the firing pin. Align the firing pin and spring with the retaining pin hole and insert the retaining pin. Ensure the pin is fully seated.
4. **Reinstall the Bolt Assembly:** Carefully slide the bolt assembly back into the upper receiver.
5. **Reassemble the Firearm:** Follow Ruger’s instructions for reassembling the Ruger Mark IV 22/45.
6. **Function Check:** Perform a function check to ensure the firearm is operating correctly. Cycle the bolt manually and dry-fire (in a safe direction) to ensure the firing pin is striking the chamber face.
## Common Mistakes and How to Avoid Them
* **Losing Small Parts:** The firing pin retaining pin and extractor retaining pin are small and easily lost. Work in a well-lit area and use a work mat to prevent loss.
* **Damaging Retaining Pins:** Use the correct size punch and apply gentle pressure to avoid bending or breaking the retaining pins.
* **Forgetting Spring Orientation:** Pay attention to the orientation of the extractor and firing pin springs during disassembly. Improper orientation can prevent proper function.
* **Over-Lubricating:** Use lubricant sparingly. Over-lubrication can attract dirt and grime, leading to malfunctions.
* **Skipping the Function Check:** Always perform a function check after reassembly to ensure the firearm is operating correctly.

* **Use a Dedicated Disassembly Tool:** A dedicated disassembly tool, like the Tandemkross tool, greatly simplifies the process of removing the bolt stop pin and makes subsequent disassembly easier. This tool helps prevent damage to the receiver and ensures consistent results.
* **Soak Heavily Fouled Parts:** If your bolt is heavily fouled, soak the components in cleaning solvent for several hours before cleaning. This will help loosen the carbon buildup and make cleaning easier.
* **Inspect for Wear and Damage:** During disassembly, carefully inspect all components for wear or damage. Replace any worn or damaged parts to ensure reliable performance.
* **Use Compressed Air:** After cleaning, use compressed air to blow out any remaining solvent or debris from the bolt components.
* **Apply a Thin Coat of Lubricant:** After cleaning and drying, apply a thin coat of gun oil or lubricant to all moving parts. This will help prevent corrosion and ensure smooth operation.
