Where do you find this crucial tool? The good news is that parts diagrams are readily available. Here are the most common sources:
- Manufacturer Websites: Mossberg (and many other firearm manufacturers) often provide detailed parts diagrams on their official websites. This is usually the most reliable and accurate source.
- Gun Part Retailers: Online retailers specializing in gun parts typically host parts diagrams to aid customers in identifying and ordering replacement components.
- Online Forums and Communities: Enthusiasts often share diagrams and related information in online forums dedicated to firearms.
- Owner’s Manual: If you are lucky enough to have the original owner’s manual that accompanied your Mossberg 500, it may contain a parts diagram.

Reading the Diagram
Once you have located a Mossberg 500 Parts Diagram, the real work begins. The diagram usually utilizes a numbering system to identify each part. Each numbered component corresponds to a specific name or description in an accompanying parts list. Arrows and lines indicate how the pieces fit together. Take your time to study the diagram. The more familiar you become with it, the easier it will be to identify parts, troubleshoot issues, and perform maintenance.
It is also critical to ensure you have the correct diagram for your specific Mossberg 500 model. Different gauges (such as twelve gauge and twenty gauge) and variations (e.g., the Persuader, Cruiser, or Field models) will have slight differences in their components. Always double-check the diagram’s compatibility with your particular shotgun model.
Breaking Down the Core Components
Now, let’s dive into the key components of the Mossberg 500 and how they interact. Understanding these elements will significantly enhance your ability to use the Mossberg 500 Parts Diagram effectively.
The Receiver and Barrel Assembly
The heart of the shotgun is the receiver. This is the primary housing unit that holds all the internal action mechanisms and the barrel. The receiver is typically made of steel or an alloy and is designed to withstand the pressures generated when firing. The barrel is attached to the receiver and channels the projectiles. The forend or slide is a sliding handguard that is moved back and forth to cycle the action. The Magazine tube and end cap: The magazine tube is the tube that holds the shells, and is attached to the receiver. The end cap keeps the shells from falling out and closes the end of the tube.
The Bolt and Firing System
The bolt is the core component responsible for locking the cartridge in the chamber and firing the shotgun. It contains a series of parts critical for the firearm’s operation. The Bolt assembly includes the bolt itself, plus parts such as the ejector and extractor.
The bolt locks into the barrel extension to prevent the breech from opening during the firing of a shell. The firing pin is the needle-like component that strikes the primer of the shotgun shell to ignite the powder. The firing pin spring provides the necessary force to propel the firing pin forward. The extractor is a small hook-like component that grabs the rim of the spent shell casing and pulls it from the chamber. The ejector then throws the expended shell out of the gun.
Trigger Group and Safety
The trigger group is the collection of parts that, when actuated, initiate the firing sequence. The trigger is the part you pull to fire the shotgun. The trigger group contains the trigger itself, along with the sear (which holds the firing pin in place), the disconnector (which ensures the trigger must be reset before it can fire again), and the trigger spring, and a number of pins and housings.
The safety switch is a crucial safety feature. It prevents the shotgun from firing accidentally. The safety mechanism consists of the safety button (typically located at the top of the receiver) and internal components that block the trigger or firing pin.
Stock and Furniture
The stock is the part of the shotgun that rests against your shoulder, providing support and aiding in aim. It helps absorb the recoil of firing the weapon. The forend, also known as the slide, is the pump-action handguard you grip to cycle shells and chamber a new round. You will likely find a pistol grip or a tactical pistol grip if the Mossberg has been modified. Finally, the shotgun could have accessories such as sling swivels, which are small connectors that allow you to attach a carrying strap.
Maintenance and Troubleshooting with the Mossberg 500 Parts Diagram
The Mossberg 500 Parts Diagram isn’t just for identification; it’s a powerful tool for maintenance and troubleshooting.
Regular cleaning and lubrication are essential for maintaining the reliability and performance of your shotgun. The parts diagram allows you to safely disassemble your Mossberg 500 for cleaning. Following the diagram, you can remove parts, clean them, and reassemble them correctly.
When your shotgun malfunctions, the parts diagram is invaluable. For instance, if the shotgun fails to feed, study the diagram to examine the magazine tube, the shell lifter, and the bolt assembly. A failure to extract could point to a damaged extractor or a dirty chamber. By consulting the diagram, you can isolate the problem and identify the specific components that need attention.
Important: Safety first! Always unload the shotgun and ensure it’s clear before any disassembly or maintenance work. Review the parts diagram to understand the proper order of disassembly. This is especially important when working with any component in the trigger group or around the firing pin.
To perform these tasks, you’ll need some basic tools, such as:
- A gun cleaning kit (brushes, solvents, and lubricants)
- Screwdrivers (for removing screws)
- A punch set (to remove pins)
- A cleaning rod (for the barrel)
