* **Accuracy:** A clean bolt contributes to consistent firing and improved accuracy.
* **Longevity:** Proper lubrication protects internal components from wear and corrosion, extending the life of your pistol.
* **Inspection:** Disassembly allows you to inspect for wear, damage, or broken parts.
* **Safety:** A well-maintained firearm is a safer firearm.
## Essential Tools for Stripping a Ruger MK IV Bolt
Before you begin, gather the necessary tools:
* **Ruger MK IV Bolt Disassembly Tool:** While not strictly essential, a dedicated tool significantly simplifies the process, especially removing the extractor and firing pin. Several excellent options are available from reputable manufacturers like TANDEMKROSS and Majestic Arms.
* **Small Punch Set:** A set of small punches is crucial for drifting out pins without damaging them. A 1/16″ punch is particularly useful.
* **Small Hammer or Mallet:** A small hammer or mallet is needed to tap the punches.
* **Cleaning Supplies:** Gun solvent, brushes, patches, and a lint-free cloth are essential for cleaning the bolt components.
* **Lubricant:** A high-quality gun lubricant, such as CLP (Clean, Lubricate, Protect), is necessary for lubricating the bolt after cleaning.
* **Small Screwdriver Set:** Having a set of small screwdrivers will help with some of the smaller screws.
* **Safety Glasses:** Always wear safety glasses to protect your eyes from flying debris.
* **Work Mat:** A clean, well-lit workspace is essential. A gun cleaning mat will protect your work surface and prevent small parts from getting lost.
## Step-by-Step Guide to Stripping a Ruger MK IV Bolt
**Safety First:** Before proceeding, ensure your Ruger MK IV is unloaded and the magazine is removed. Verify the chamber is empty. Always handle firearms responsibly.
1. **Bolt Removal:** Remove the bolt from the pistol. Refer to your Ruger MK IV owner’s manual for instructions on field stripping the pistol.
2. **Firing Pin Removal (Using a Disassembly Tool):**
* If you have a dedicated bolt disassembly tool, follow the manufacturer’s instructions. Typically, this involves inserting the bolt into the tool and using leverage to compress the firing pin spring, allowing you to remove the firing pin retaining pin. The TANDEMKROSS tool is particularly effective for this.
* **Without a Disassembly Tool:** This method requires more care and precision. Place the bolt on a firm surface with the firing pin facing up. Use a small punch (1/16″) to gently depress the firing pin. While holding the firing pin depressed, use another punch to drift out the firing pin retaining pin. Be careful, as the firing pin and spring are under tension.
3. **Extractor Removal:**
* **Using a Disassembly Tool:** The disassembly tool often includes a feature for depressing the extractor plunger. Use the tool to compress the plunger and remove the extractor retaining pin.
* **Without a Disassembly Tool:** This is arguably the trickiest part of the process. Carefully position the bolt. Use a small punch to gently depress the extractor plunger. While holding the plunger depressed, use another punch to drift out the extractor retaining pin. The extractor and plunger are small and spring-loaded, so be prepared for them to potentially launch when the pin is removed. Work slowly and deliberately.
4. **Cleaning:** Once the bolt is completely disassembled, thoroughly clean all components with gun solvent and a brush. Pay particular attention to the firing pin channel and the extractor groove. Use patches to remove any residue. Inspect all parts for wear, damage, or cracks.
5. **Lubrication:** Lightly lubricate all moving parts with a high-quality gun lubricant. Focus on the firing pin, extractor, and their respective springs and channels. Avoid over-lubrication, as excess lubricant can attract dirt and grime.
6. **Reassembly:**
* **Extractor Reassembly:** Reinstall the extractor, plunger, and retaining pin. Use a punch to align the pin holes and gently tap the pin into place.
* **Firing Pin Reassembly:** Reinstall the firing pin, spring, and retaining pin. Again, a disassembly tool simplifies this process. If reassembling without a tool, carefully compress the firing pin spring and align the pin holes before tapping the pin into place.
7. **Bolt Reinstallation:** Reinstall the bolt into the pistol. Refer to your Ruger MK IV owner’s manual for instructions.
8. **Function Check:** After reassembly, perform a function check to ensure the pistol is operating correctly. Verify that the firing pin moves freely and that the extractor properly engages the cartridge rim.
## Common Pitfalls and Troubleshooting
* **Lost Parts:** The extractor, plunger, and retaining pins are very small and easily lost. Work in a well-lit area and be careful when disassembling the bolt.
* **Damaged Pins:** Using excessive force when drifting out pins can damage them. Use the correct size punch and tap gently.
* **Extractor Plunger Binding:** The extractor plunger can sometimes bind due to carbon buildup. Thoroughly clean the plunger and its channel.
* **Firing Pin Channel Obstruction:** A build-up of debris in the firing pin channel can cause light strikes. Use a pipe cleaner or small brush to clean the channel thoroughly.
* **Incorrect Reassembly:** Ensure all parts are reassembled correctly. Refer to the diagrams and instructions in this guide.
## Advanced Tips for Ruger MK IV Bolt Maintenance
* **Ultrasonic Cleaning:** For heavily soiled bolts, ultrasonic cleaning can be very effective. However, be sure to thoroughly lubricate the bolt after ultrasonic cleaning to prevent corrosion.
* **Polishing:** Polishing the firing pin and extractor can improve their smoothness and reliability. Use a fine polishing compound and a soft cloth.
* **Upgraded Parts:** Consider upgrading to aftermarket parts, such as a lighter firing pin spring or a more aggressive extractor, to improve performance.
* **Regular Inspection:** Inspect your Ruger MK IV bolt regularly for wear, damage, or cracks. Replace any worn or damaged parts immediately.
## Ruger MK IV Bolt Disassembly Tools: A Closer Look
While it’s possible to **strip a Ruger MK IV bolt** without specialized tools, a dedicated disassembly tool can significantly simplify the process and reduce the risk of damaging parts. Several excellent options are available, each with its own advantages:
* **TANDEMKROSS Bolt Keeper:** This tool is highly regarded for its ease of use and effectiveness. It provides a secure platform for disassembling and reassembling the bolt, making it easier to compress the firing pin spring and remove the extractor pin.
* **Majestic Arms Ruger MK IV Bolt Disassembly Tool:** Another popular option, the Majestic Arms tool is known for its robust construction and versatility. It can be used to disassemble and reassemble various Ruger MK series bolts.
* **DIY Solutions:** Some shooters have fabricated their own bolt disassembly tools using simple materials like wood or plastic. While this can be a cost-effective option, it requires some mechanical skill and ingenuity.
Choosing the right tool depends on your budget, skill level, and personal preferences. However, investing in a quality bolt disassembly tool can save you time, frustration, and potential damage to your Ruger MK IV.
## Cleaning Solvents and Lubricants: Choosing the Right Products
The choice of cleaning solvents and lubricants is crucial for maintaining your Ruger MK IV bolt. Different products offer varying levels of cleaning power, corrosion protection, and lubrication. Here are some popular options:
