Buying Guide for Mossberg 590 Picatinny Rail

Understanding the Purpose of a Picatinny Rail

When I first looked into upgrading my Mossberg 590, I realized that a Picatinny rail is essential for mounting various accessories like optics, lights, or lasers. This rail system provides a standardized mounting platform, ensuring that attachments fit securely and align properly. Knowing this helped me focus on rails that offer durability and compatibility.

Compatibility with Mossberg 590

The Mossberg 590 has specific design features, so I made sure the Picatinny rail I considered was explicitly compatible with this model. Some rails are designed for the 590A1 or other Mossberg variants, so checking the fitment prevents installation issues. I always recommend verifying the rail’s mounting method and whether it requires any modifications to the shotgun.

Material and Build Quality

I paid close attention to the material of the rail because it affects durability and weight. Most quality Picatinny rails are made from aluminum or steel. Aluminum is lightweight and resistant to corrosion, which suits my needs for longer shooting sessions without adding excessive weight. Steel rails, while heavier, offer extra toughness. Considering how I planned to use my shotgun, I balanced these factors carefully.

Installation Process

Ease of installation was a big factor for me. Some Picatinny rails for the Mossberg 590 require professional gunsmithing, while others come with straightforward mounting kits. I looked for rails that matched my skill level in installation and whether I had the right tools. Reading user reviews about installation helped me avoid complicated setups.

Rail Length and Positioning

The length of the Picatinny rail determines how many accessories you can mount and where. I thought about whether I wanted a short rail just for a red dot sight or a longer rail that could accommodate multiple attachments. Positioning also matters since it affects comfort and accessibility. I chose a rail length that balanced functionality without interfering with the shotgun’s handling.

Weight Considerations

Adding a Picatinny rail changes the shotgun’s weight distribution. I noticed that heavier rails made the shotgun front-heavy, which affected my aiming speed and comfort. Therefore, I considered the rail’s weight along with the accessories I planned to mount to maintain good balance.

Durability and Finish

Since I use my Mossberg 590 in various environments, I looked for rails with durable finishes like anodizing or parkerizing. These finishes protect against rust, scratches, and general wear and tear. A high-quality finish extends the life of the rail and keeps my shotgun looking and performing well.

Price vs. Quality

My budget played a role, but I didn’t want to compromise on quality. I compared different price points and matched them with the features offered. Sometimes paying a bit more meant better materials and a longer-lasting product. I recommend balancing cost with reliability and intended use.

Additional Features

Some Picatinny rails come with extra features like integrated sling mounts or quick-detach capabilities. Depending on how I use my shotgun, these features can be very beneficial. I assessed whether these extras were necessary for my setup or just added weight and complexity.

Final Thoughts

Choosing the right Picatinny rail for my Mossberg 590 required evaluating compatibility, build quality, installation ease, and how the rail would affect the shotgun’s handling. Taking the time to research and consider these factors made my upgrade more satisfying and practical. I recommend anyone looking to buy a Picatinny rail for their Mossberg 590 to carefully weigh these aspects before making a decision.
