Step-by-Step Disassembly of the Ruger Mark IV 22/45 Bolt

Follow these steps carefully to safely and effectively disassemble your Ruger Mark IV 22/45 bolt. Remember to work in a well-lit area and keep all parts organized.

Safety First

Before you begin any disassembly, ensure that the firearm is unloaded and safe. Remove the magazine and visually inspect the chamber to confirm that it is empty. Always handle firearms with respect and follow all safety guidelines.

Removing the Bolt from the Pistol

Disassembling the Bolt Components

Remove the Firing Pin Retaining Pin: Using a punch and hammer, gently drive out the firing pin retaining pin. Support the bolt on a solid surface while doing this.
Remove the Firing Pin: Once the retaining pin is removed, the firing pin can be easily pushed out from the rear of the bolt.
Remove the Extractor: The extractor is held in place by a pin and spring. Use a punch to carefully depress the extractor plunger and remove the extractor pin. The extractor and extractor spring can then be removed. Be careful as the spring is small and can easily be lost.
Remove the Ejector: The ejector is typically fixed in the bolt and does not require disassembly for routine cleaning. However, if necessary, it can be removed by driving out its retaining pin. This step is generally not recommended unless the ejector is damaged or requires replacement.

Cleaning the Bolt Components

After disassembling the Ruger Mark IV 22/45 bolt, thoroughly clean each component to remove any residue or grime. Use a cleaning solvent and appropriate brushes and patches to clean the bolt body, firing pin, extractor, and other parts. Pay close attention to areas where carbon buildup is common.

Bolt Body: Clean the interior and exterior surfaces of the bolt body. Use a brush to remove any stubborn residue.
Firing Pin: Clean the firing pin with a solvent and ensure that it moves freely within the bolt.
Extractor: Clean the extractor hook and ensure that it is free from any debris.

Inspecting the Bolt Components

While cleaning, carefully inspect each component for signs of wear, damage, or corrosion. Replace any parts that are worn or damaged to ensure the reliable operation of your Ruger Mark IV 22/45. Common areas to inspect include the firing pin tip, extractor hook, and bolt face.

Reassembling the Ruger Mark IV 22/45 Bolt

Reassembly is the reverse of the disassembly process. Follow these steps carefully to ensure that all components are properly installed.

Install the Ejector (if removed): Align the ejector with its slot in the bolt and drive in the retaining pin.
Install the Extractor: Insert the extractor spring and extractor into their respective slots. Depress the extractor plunger and insert the extractor pin to secure the extractor in place.
Install the Firing Pin: Insert the firing pin into the rear of the bolt.
Install the Firing Pin Retaining Pin: Align the firing pin retaining pin hole and drive in the retaining pin to secure the firing pin.

Lubricating the Bolt

After reassembling the Ruger Mark IV 22/45 bolt, apply a light coat of lubricant to the moving parts. This will ensure smooth operation and prevent wear. Focus on lubricating the firing pin, extractor, and bolt body. [See also: Best Lubricants for .22 Pistols]

Reinstalling the Bolt into the Pistol

Once you have confirmed that the Ruger Mark IV 22/45 bolt is properly reassembled and functioning correctly, you can reinstall it into the pistol. Align the bolt with the receiver and slide it in from the rear. Secure the bolt by closing the mainspring housing and ensuring that the takedown button is engaged.
