## Understanding Mossberg 590 Barrel Options and Compatibility
The Mossberg 590 is renowned for its modularity, making it a popular choice for home defense, hunting, and tactical applications. A key aspect of this modularity is the ability to swap barrels, allowing you to adapt the shotgun to different scenarios. However, not all barrels are created equal, and understanding compatibility is paramount.
### Barrel Length and Its Impact
Barrel length is a critical factor influencing the shotgun’s handling, maneuverability, and effective range. Shorter barrels (e.g., 18.5 inches) are ideal for close-quarters combat and home defense due to their compact size and quick handling. Longer barrels (e.g., 20 inches or more) offer improved accuracy and range, making them suitable for hunting and target shooting. When considering a *Mossberg 590 barrel swap*, carefully evaluate your intended use to determine the optimal barrel length.
### Choke Systems and Their Function
Chokes are constrictions at the muzzle of the barrel that control the spread of the shot pattern. Different chokes are designed for different types of ammunition and shooting scenarios. For example, a cylinder bore choke provides no constriction and is suitable for buckshot and slugs at close range. A full choke provides the tightest constriction and is ideal for waterfowl hunting at longer distances. Some *Mossberg 590 barrels* come with interchangeable choke tubes, allowing you to fine-tune the shot pattern to your specific needs. Understanding choke systems is essential for maximizing the effectiveness of your *Mossberg 590 barrel*. Many aftermarket barrels come with a variety of chokes, allowing for a greater degree of customization.
### Magazine Tube Compatibility: A Critical Consideration
One of the most critical aspects of a *Mossberg 590 barrel swap* is ensuring compatibility with your existing magazine tube. The barrel length must match the magazine tube capacity. For instance, an 18.5-inch barrel typically pairs with a 6-shot magazine tube, while a 20-inch barrel often corresponds to an 8-shot magazine tube. Using an incompatible barrel and magazine tube combination can lead to feeding issues and potentially damage your shotgun. Always verify compatibility before proceeding with the swap. In our experience, this is the most common mistake people make when performing a *Mossberg 590 barrel swap*.
### Ghost Ring Sights vs. Bead Sights
Another consideration when choosing a *Mossberg 590 barrel* is the type of sights. Some barrels come with traditional bead sights, while others feature ghost ring sights. Bead sights are simple and effective for quick target acquisition, while ghost ring sights offer improved accuracy and precision, especially at longer ranges. The choice depends on your personal preference and intended use. Many tactical shooters prefer ghost ring sights for their enhanced accuracy.
## Performing a Mossberg 590 Barrel Swap: A Step-by-Step Guide
Swapping the barrel on a Mossberg 590 is a relatively straightforward process, but it’s crucial to follow proper safety procedures and take your time to avoid damaging your shotgun. Here’s a detailed step-by-step guide:
### Step 1: Ensure the Firearm is Unloaded and Safe
This is the most important step. Always double-check that the shotgun is completely unloaded before proceeding. Remove the magazine tube cap and ensure there are no shells in the magazine tube or chamber. Visually inspect the chamber to confirm it’s empty. Treat every firearm as if it is loaded.
### Step 2: Remove the Magazine Tube Cap and Barrel
Unscrew the magazine tube cap at the end of the magazine tube. Be careful, as the spring inside is under tension. Once the cap is removed, carefully slide the barrel forward, away from the receiver. The barrel should come off easily. If it doesn’t, double-check that the magazine tube cap is completely removed and that there are no obstructions.
### Step 3: Install the New Barrel
Align the new barrel with the receiver and slide it into place. Ensure that the barrel is fully seated and that the magazine tube lug on the barrel aligns correctly with the magazine tube.
### Step 4: Reinstall the Magazine Tube Cap
Carefully compress the magazine tube spring and reinstall the magazine tube cap. Tighten the cap securely, but avoid over-tightening it, as this could damage the threads. A snug fit is sufficient.
### Step 5: Function Check
After installing the new barrel, perform a function check to ensure that the shotgun is operating correctly. Cycle the action to chamber a dummy round and verify that it feeds and ejects properly. Check the safety to ensure that it engages and disengages smoothly. If you encounter any issues, consult a qualified gunsmith.
### Safety Precautions: A Must-Read
* **Always wear eye protection** when performing any firearm maintenance or modification.
* **Work in a well-lit and uncluttered area** to avoid accidents.
* **If you are unsure about any step of the process**, consult a qualified gunsmith.
* **Never attempt to modify any firearm without proper knowledge and experience.**
## Choosing the Right Mossberg 590 Barrel: Factors to Consider
Selecting the right *Mossberg 590 barrel* for your needs requires careful consideration of several factors. Here’s a breakdown of the key aspects to keep in mind:
### Intended Use: Defining Your Needs
The primary factor in choosing a barrel is your intended use for the shotgun. If you plan to use it primarily for home defense, a shorter barrel (18.5 inches) is generally the best choice due to its maneuverability in tight spaces. For hunting or target shooting, a longer barrel (20 inches or more) may be more suitable for its improved accuracy and range. Consider what you’ll primarily use the shotgun for to make the best decision.
### Budget: Balancing Cost and Quality
*Mossberg 590 barrels* are available in a wide range of prices. Generally, higher-priced barrels are made from better materials and offer superior craftsmanship. However, you can still find excellent options within a reasonable budget. Set a budget before you start shopping and stick to it. Remember that a quality barrel is an investment in your safety and the performance of your shotgun.
### Material and Construction: Durability and Performance
The material and construction of the barrel significantly impact its durability and performance. Look for barrels made from high-quality steel, such as 4140 or 4150 chrome-moly steel. Chrome-lined barrels offer enhanced corrosion resistance and are easier to clean. The barrel should also be properly heat-treated to ensure its strength and longevity.
### Sights and Optics: Enhancing Accuracy
Consider the type of sights you prefer when choosing a *Mossberg 590 barrel*. As mentioned earlier, options include bead sights, ghost ring sights, and even barrels with Picatinny rails for mounting optics. If you plan to use a red dot sight or other optic, make sure the barrel is compatible.
### Aftermarket Options vs. Factory Barrels
Both aftermarket and factory *Mossberg 590 barrels* have their advantages. Factory barrels are typically more affordable and guaranteed to be compatible with your shotgun. Aftermarket barrels often offer more features and customization options, such as different choke systems, sights, and finishes. Research different brands and read reviews before making a decision.
