Cleaning the Bolt Components

After disassembling the bolt, thoroughly clean each component to remove carbon buildup, fouling, and any other debris. Use a cleaning solvent and cleaning patches to wipe down each part. Pay particular attention to the firing pin channel and the extractor claw. A clean bolt is crucial for reliable operation. Make sure to allow the solvent to completely evaporate before reassembling. A clean Ruger MK IV bolt ensures smooth cycling and reliable firing.

Inspecting the Bolt Components

While cleaning, take the opportunity to inspect each component for wear and tear. Look for cracks, chips, or excessive wear on the firing pin, extractor, and ejector. Replace any parts that are damaged or worn. Replacing worn parts prevents misfires and extraction failures. Regular inspection while you strip a Ruger MK IV bolt can save you headaches later.

Reassembling the Ruger MK IV Bolt

Reassembly is essentially the reverse of disassembly. Follow these steps to reassemble your Ruger MK IV bolt:

Install the Ejector: Slide the ejector into its slot and insert the ejector pin.
Install the Extractor Plunger and Spring: Place the spring in the hole and then insert the plunger.
Install the Extractor: Depress the plunger and slide the extractor into place.
Install the Firing Pin: Slide the firing pin into the bolt body.
Install the Firing Pin Retaining Pin: Align the holes and insert the retaining pin. Gently tap it with the hammer until it is flush with the bolt body.

Ensure all parts move freely and function correctly. A properly reassembled bolt is essential for safe and reliable operation. After you strip a Ruger MK IV bolt and reassemble, function check is critical.

Lubricating the Bolt

After reassembling the bolt, lightly lubricate the moving parts with gun oil. Pay particular attention to the firing pin channel and the extractor. Lubrication helps to reduce friction and prevent wear. Do not over-lubricate, as this can attract dirt and debris. A little goes a long way. The right amount of lubrication after you strip a Ruger MK IV bolt ensures smooth cycling.

Function Check

Before re-installing the bolt in the pistol, perform a function check to ensure that everything is working correctly. Check that the firing pin moves freely and that the extractor and ejector are functioning properly. A function check is an important safety measure. This step verifies everything is working correctly after you strip a Ruger MK IV bolt and put it back together.

Reinstalling the Bolt

Follow the instructions in your Ruger MK IV owner’s manual for reinstalling the bolt into the pistol’s receiver. Ensure that the bolt is properly seated and that all components are correctly aligned. A properly installed bolt is essential for safe and reliable operation. Make sure it locks up correctly after you strip a Ruger MK IV bolt and reinstall it.

Safety Precautions

Always follow these safety precautions when working with firearms:

Always treat every firearm as if it is loaded.
Never point a firearm at anything you are not willing to destroy.
Keep your finger off the trigger until you are ready to fire.
Be sure of your target and what is beyond it.
