The Mossberg 500 is a legendary pump-action shotgun, renowned for its reliability, affordability, and versatility. At the core of this firearm's functionality lies its action tube – a seemingly simple component that plays a crucial role in the gun's operation and overall performance. This article delves deep into the Mossberg 500 action tube, exploring its function, common issues, and potential upgrades.
Understanding the Mossberg 500 Action Tube's Function
The action tube, located beneath the barrel, is the heart of the Mossberg 500's pump-action mechanism. It's a hollow tube that houses the shotgun's shells, acting as a crucial conduit for feeding ammunition into the chamber. Its function is multifaceted:
- Shell Storage: The primary function is to hold the shells, typically holding up to six rounds depending on the model and configuration.
- Shell Feeding: As the pump action is cycled, the action tube pushes shells forward, feeding them into the chamber for firing. This process is smooth and reliable, contributing to the 500's legendary dependability.
- Mechanical Linkage: The action tube is intricately linked to the pump mechanism, ensuring precise and consistent operation. Any issues with the tube can directly affect the entire firearm's functionality.
Common Problems with Mossberg 500 Action Tubes
While robust, Mossberg 500 action tubes can sometimes experience issues, often stemming from heavy use or improper maintenance:
- Tube Jams: This is a common problem, often caused by dirt, debris, or deformed shells obstructing the smooth movement of shells within the tube. Regular cleaning is vital to prevent jams.
- Rust and Corrosion: Exposure to moisture can lead to rust, potentially causing the tube to seize or malfunction. Proper storage and regular lubrication are crucial for preventing corrosion.
- Damage from Overuse: Intensive use can cause wear and tear, possibly leading to dents, scratches, or even cracks in the action tube. Regular inspection can help catch potential problems early.
Upgrading Your Mossberg 500 Action Tube
For enthusiasts seeking enhanced performance or specific features, aftermarket upgrades are available:
- Extended Tubes: These tubes increase the shell capacity, offering a tactical advantage in certain situations. However, remember to check local laws and regulations regarding magazine capacity.
- Different Finishes: Some aftermarket tubes offer different finishes, such as Cerakote, providing added protection against corrosion and wear.
- Custom Engraved Tubes: For those seeking a personalized touch, custom-engraved action tubes are available, adding a unique aesthetic to their firearm.
Important Note: Before attempting any modifications or repairs to your Mossberg 500 action tube, it's crucial to consult a qualified gunsmith. Improper modification can damage the firearm and compromise its safety.
