Step 2: Disassembling the Shotgun
Removing the Barrel and Trigger Group
With your Mossberg 590 unloaded, it’s time to disassemble the shotgun for a thorough cleaning. Begin by moving the forearm to a middle position where the action is halfway open. Locate the takedown screw at the end of the magazine tube and unscrew it to release the barrel. Carefully pull the barrel forward to remove it from the gun.
Next, you’ll need to remove the trigger group. Use a non-marring tool to push the trigger group pin out of the gun from the right side. Once the pin is removed, pull down and aft on the rear of the trigger guard to remove the trigger group.
Removing Additional Components
In addition to the barrel and trigger group, there are a few more components that need to be removed for a thorough disassembly. Starting with the cartridge interceptor, locate it on the right sidewall of the gun and remove it. Similarly, locate the cartridge stop on the left sidewall and remove it as well.
To remove the bolt, align it with the relief cuts in the receiver and pull it out from the bottom. This will allow you to access and clean the bolt more effectively. Finally, remove the forearm by pulling it forward and the elevator by pinching the arms together. With these steps completed, your Mossberg 590 is now fully disassembled for cleaning and inspection.
| Components | Removal Method |
|---|---|
| Barrel | Unscrew takedown screw and pull forward |
| Trigger Group | Push trigger group pin out and pull down and aft on the rear of the trigger guard |
| Cartridge Interceptor | Remove from the right sidewall of the gun |
| Cartridge Stop | Remove from the left sidewall of the gun |
| Bolt | Align with relief cuts in the receiver and pull out from the bottom |
| Forearm | Pull forward |
| Elevator | Pinch arms together |
Step 3: Optional Steps for Further Disassembly
If you want to take your Mossberg 590 disassembly to the next level, there are a couple of optional steps you can undertake. These steps allow for a more thorough cleaning and maintenance of your shotgun, ensuring its optimal performance for years to come.
Removing the Ejector
To remove the ejector, simply unscrew the screw that holds it in place on the left sidewall of the gun. This allows you to access and clean the ejector, removing any dirt or debris that may have accumulated over time. Taking the time to clean the ejector can help prevent malfunctions and ensure reliable ejection of spent shells.
Disassembling the Magazine Tube
If you want to go even further, you can also disassemble the magazine tube of your Mossberg 590. This step requires caution and the use of a cleaning kit to properly clean the spring and follower inside the magazine tube. Unscrew the magazine tube from the receiver, being mindful of the slight spring pressure. Once disassembled, you can clean each component thoroughly to remove any buildup or residue.
By including these optional steps in your Mossberg 590 cleaning routine, you can ensure that every part of your shotgun is meticulously cleaned and maintained. This attention to detail will contribute to its overall reliability and performance, making it a trusted companion in the field or at the range.
| Optional Steps | Description |
|---|---|
| Removing the Ejector | Unscrew the ejector from the left sidewall to clean and maintain proper function. |
| Disassembling the Magazine Tube | Carefully unscrew the magazine tube to access the spring and follower for thorough cleaning. |
Step 4: Cleaning and Inspection
Now that you have disassembled your Mossberg 590, it’s time to move on to the crucial step of cleaning and inspection. By thoroughly cleaning and inspecting each component, you can ensure that your shotgun will continue to provide reliable service and perform optimally when needed.
Start by gathering the necessary cleaning solvents, lubricants, and tools. These may include bore brushes, cleaning patches, solvent sprays, a cleaning rod, and a soft cloth. Use these tools to remove any dirt, debris, or residue from the barrel, receiver, and other parts. Pay extra attention to areas that are prone to buildup, such as the action and trigger group.
During the cleaning process, it’s important to inspect each component for any signs of wear, damage, or corrosion. Check the barrel for any pitting or rust, ensuring that it is smooth and free from obstructions. Examine the receiver for any cracks or deformities, as well as the trigger group for any broken or worn parts. Inspecting your shotgun allows you to identify potential issues early on and address them before they develop into major problems.
Table: Mossberg 590 Cleaning Checklist
| Component | Cleaning Steps | Inspection Steps |
|---|---|---|
| Barrel | 1. Use a bore brush and solvent to remove fouling 2. Run cleaning patches through the bore until they come out clean | Check for signs of pitting, rust, or obstructions |
| Receiver | 1. Wipe down the receiver with a soft cloth 2. Apply lubricant to moving parts as needed | Inspect for cracks, deformities, or signs of excessive wear |
| Trigger Group | 1. Clean all accessible parts with a brush and solvent 2. Apply lubricant to moving parts as needed | Check for broken or worn components |
| Other Parts | 1. Clean and lubricate any additional components 2. Remove and clean the forearm and elevator if necessary | Inspect for any signs of wear, damage, or corrosion |
After cleaning and inspecting each component, ensure that all excess solvent and debris have been removed. Wipe down the shotgun with a soft cloth to give it a clean and polished finish. Once you are satisfied with the cleanliness and condition of your Mossberg 590, you can proceed to the next step of reassembling the shotgun.
Step 5: Reassembling the Shotgun
Now that we have thoroughly cleaned and inspected each component of the Mossberg 590, it’s time to put it all back together. Follow these steps to ensure a successful reassembly:
1. Begin by inserting the elevator back into its position. This small but important part helps feed the shotshells into the chamber smoothly.
2. Next, carefully slide the bolt back into the receiver. Make sure it aligns properly with the relief cuts in the receiver and smoothly glides into place.
3. Reattach the cartridge stop, followed by the cartridge interceptor. These parts play a crucial role in the feeding and extraction of shotshells, so ensure they are securely fastened.
4. Insert the trigger group back into the action, making sure it fits snugly. Secure it with the trigger group pin, ensuring it is properly aligned and correctly inserted.
5. Reattach the barrel by screwing the takedown screw onto the end of the magazine tube. Make sure it is tightened securely, but be cautious not to overtighten.
Remember, safety is paramount. Before storing or using the Mossberg 590, ensure that the firearm is unloaded and perform a functionality test. This step ensures that the shotgun is reassembled correctly and in proper working order.
By following these steps, you can confidently reassemble your Mossberg 590 shotgun and have it ready for your next shooting adventure.
