Understanding the Ruger Mark IV 22/45 Bolt Assembly

The Ruger Mark IV 22/45 is a popular .22 caliber pistol known for its reliability and accuracy. A key component of its operation is the bolt assembly. Understanding the function and construction of the bolt is crucial before attempting any disassembly. The bolt cycles back and forth during firing, extracting spent cartridges, cocking the hammer, and chambering new rounds. Its proper function is vital for safe and reliable operation of the firearm. Failing to properly maintain the bolt can lead to malfunctions and reduced accuracy. Understanding its components and how they interact is the first step to successful disassembly and maintenance. Recent studies indicate that improper cleaning is a primary cause of malfunctions in rimfire pistols.

The bolt itself is more than just a simple piece of metal. It comprises several interconnected parts, each with a specific purpose. These include the firing pin, extractor, ejector, and various springs and pins that hold everything together. Knowing the names and functions of these parts is essential for understanding the disassembly and reassembly process. We will cover each component in detail later in this guide.

* Inspect the firing pin for any signs of damage or wear.

4. **Remove the Extractor Plunger and Spring:**
* Locate the extractor on the side of the bolt.
* Using a small punch or tool, carefully depress the extractor plunger.
* While depressing the plunger, use a small pick or screwdriver to remove the extractor from the bolt.
* Be careful, as the plunger and spring are under pressure and can easily fly out.
* Once the extractor is removed, carefully remove the extractor plunger and spring.

5. **Remove the Ejector (If Necessary):**
* The ejector is typically held in place by a pin.
* If you need to remove the ejector for cleaning or replacement, use a small punch and hammer to tap out the ejector pin.

* Carefully insert the firing pin into the rear of the bolt.
* Ensure the firing pin is properly aligned.

4. **Install the Firing Pin Retaining Pin:**
* Align the holes in the firing pin and bolt.
* Insert the firing pin retaining pin and tap it into place using a small hammer and punch.
* Ensure the pin is flush with the surface of the bolt.

5. **Test the Bolt Function:**
* After reassembly, manually cycle the bolt to ensure it functions smoothly.
* Check the extractor and ejector to ensure they are properly extracting and ejecting dummy rounds.
* Dry fire the firearm (with an empty chamber) to ensure the firing pin is striking correctly.

Troubleshooting Common Issues During Disassembly and Reassembly

* **Difficulty Removing Pins:** If you are having difficulty removing pins, try using a penetrating oil to loosen any corrosion. Ensure you are using the correct size punch.
* **Lost Parts:** Work in a well-lit area and use a work mat to prevent parts from rolling away. If you lose a part, contact Ruger or a gunsmith for a replacement.
