Step-by-Step Guide to Stripping a Ruger MK IV Bolt

Follow these steps carefully to strip a Ruger MK IV bolt safely and effectively. Remember to always prioritize safety and consult your firearm’s manual if you have any doubts.

Step 1: Ensure the Firearm is Unloaded

This is the most critical step. Always double-check that the firearm is unloaded before beginning any disassembly. Remove the magazine and visually inspect the chamber to ensure it is empty.

Step 2: Remove the Bolt from the Pistol

Refer to your Ruger MK IV manual for instructions on how to remove the bolt from the pistol. This usually involves pressing a button or lever and sliding the bolt out of the receiver.

Step 3: Identify Bolt Components

Before disassembling the bolt, familiarize yourself with its components. These typically include the firing pin, firing pin spring, extractor, extractor spring, and various pins.

Step 4: Remove the Firing Pin Retaining Pin

Using a correctly sized punch and hammer, carefully drive out the firing pin retaining pin. Support the bolt on a firm surface to prevent damage. This pin usually runs perpendicular to the bolt’s length. Once the pin is removed, the firing pin and spring can be carefully extracted. Pay attention to the orientation of the firing pin for reassembly. If you are having trouble removing the pin, ensure you are using the correct size punch and applying gentle, consistent pressure.

Step 5: Remove the Extractor

The extractor is typically held in place by a pin and spring. Using a small punch, carefully depress the extractor plunger or spring and push out the extractor pin. Be cautious, as the spring is under tension and may launch the extractor and pin when released. Keep your fingers over the parts to prevent them from flying away. Note the orientation of the extractor for proper reassembly.

Step 6: Clean All Components

Once the bolt is completely disassembled, clean all components thoroughly with cleaning solvent and brushes. Pay particular attention to removing carbon buildup from the firing pin channel and extractor. Use a soft cloth or patch to wipe down each part. Ensure all solvent residue is removed before reassembling.

Reassembling the Ruger MK IV Bolt

Reassembly is essentially the reverse of disassembly. Follow these steps carefully to ensure proper function.

Step 1: Reinstall the Extractor

Place the extractor and its spring back into their respective positions. Depress the spring with a small punch and insert the extractor pin. Ensure the pin is fully seated and flush with the bolt surface. Test the extractor’s movement to ensure it functions smoothly.

Step 2: Reinstall the Firing Pin and Spring

Insert the firing pin and its spring into the firing pin channel. Ensure the firing pin is oriented correctly. Align the firing pin retaining pin hole and insert the retaining pin using a punch and hammer. Ensure the pin is fully seated and flush with the bolt surface. Test the firing pin’s movement to ensure it functions smoothly.

Step 3: Lubricate the Bolt

Apply a light coat of gun oil to all moving parts of the bolt, including the firing pin, extractor, and their respective springs. This will ensure smooth operation and prevent corrosion.

Step 4: Reinstall the Bolt into the Pistol

Refer to your Ruger MK IV manual for instructions on how to reinstall the bolt into the pistol. Ensure the bolt is properly seated and functions correctly.

Step 5: Perform a Function Check

After reassembling the bolt and reinstalling it into the pistol, perform a function check to ensure everything is working correctly. Cycle the action and dry-fire the pistol (in a safe direction) to ensure the firing pin is striking correctly and the extractor is functioning properly.

Tips for Stripping a Ruger MK IV Bolt

Work in a Well-Lit Area: Good lighting is essential for seeing small parts and avoiding mistakes.
Use a Parts Tray: A parts tray will help keep small components organized and prevent them from getting lost.
Take Pictures: Taking pictures of the bolt at each stage of disassembly can be helpful for reassembly.
Don’t Force Anything: If you encounter resistance, double-check that you are using the correct tools and following the correct procedure. Forcing parts can damage them.
Consult Your Manual: Your Ruger MK IV manual is a valuable resource for detailed instructions and diagrams.

Common Mistakes to Avoid

Losing Small Parts: Be careful not to lose small parts, such as springs and pins. Work in a clean and organized area.
Damaging Pins: Use the correct size punch and apply gentle, consistent pressure to avoid damaging pins.
Over-Lubricating: Applying too much oil can attract dirt and debris. Use a light coat of oil on moving parts.
Forgetting the Order of Parts: Pay attention to the order in which parts are disassembled and reassembled. Taking pictures can be helpful.

Troubleshooting

If you encounter problems during disassembly or reassembly, consult your Ruger MK IV manual or seek assistance from a qualified gunsmith. Common issues include:

Difficulty Removing Pins: Ensure you are using the correct size punch and applying gentle, consistent pressure.
Extractor Not Functioning Properly: Check the extractor spring and ensure the extractor is properly seated.
Firing Pin Not Striking Correctly: Check the firing pin spring and ensure the firing pin is properly seated.
