Why My Mossberg 590 Red Dot Mount Is Necessary
From my experience, adding a red dot mount to my Mossberg 590 has completely transformed how I use the shotgun. The primary reason I found it necessary is accuracy. With the red dot sight, I can acquire targets much faster and more precisely, especially in low-light or high-stress situations where traditional iron sights can slow me down. It gives me confidence that my shots will go exactly where I want.
Another key reason is versatility. The red dot mount allows me to customize my shotgun for different scenarios, whether it’s home defense, hunting, or tactical training. I no longer have to rely solely on bead sights, which can be limiting. Having that clear, illuminated aiming point makes transitions between targets smoother and more intuitive.
Finally, mounting a red dot on my Mossberg 590 improves overall handling. It reduces the need for perfect cheek welds or perfect eye alignment, making shooting more comfortable and natural. For me, this setup has made the shotgun feel like a more effective and user-friendly tool in any situation.
My Buying Guides on Mossberg 590 Red Dot Mount
When I decided to enhance my Mossberg 590 with a red dot sight, I quickly realized that choosing the right red dot mount is crucial. It’s not just about attaching the optic; it’s about ensuring durability, alignment, and ease of use. Here’s what I learned during my search that might help you pick the perfect Mossberg 590 red dot mount.
Compatibility with Mossberg 590
The first thing I checked was whether the mount was specifically designed for the Mossberg 590 or at least compatible with its receiver. The 590 has a unique profile compared to other shotguns, so generic mounts may not fit securely or could require modifications. I looked for mounts labeled explicitly for Mossberg 590 or 500 series to ensure a snug fit.
Mounting Style and Installation
I found that there are different mounting styles available:
- Picatinny Rails: Some mounts come with their own Picatinny rail attachment or clamp onto an existing rail. This is great if you want to use other accessories as well.
- Receiver-Mounted Bases: These attach directly to the receiver with screws, providing a solid and repeatable zero.
- Clamp-On Mounts: These clamp onto the barrel or magazine tube but can sometimes affect balance or point of impact.
I personally preferred a receiver-mounted base because it felt more stable and easier to install with basic tools.
Material and Durability
Since shotguns generate a lot of recoil, the mount must be made of strong materials like aircraft-grade aluminum or steel. I avoided plastic mounts, as I didn’t want to risk losing zero after a few shots. Checking user reviews helped me identify mounts that held up well after extended use.
Height and Eye Relief Considerations
The height of the mount affects how quickly you can acquire your sight picture. Some mounts place the red dot higher above the barrel, which can be good for clearance but might require you to adjust your cheek weld. I tested a couple of options and settled on a low-profile mount that allowed me to maintain a natural shooting position.
Compatibility with My Red Dot Sight
I had to make sure the mount was compatible with the red dot optic I intended to use. Different optics have different mounting footprints (like Aimpoint Micro, Trijicon RMR, or Holosun). Some mounts come pre-cut for certain footprints, while others offer adapter plates. I recommend confirming this beforehand to avoid surprises.
Ease of Removal and Re-zeroing
If you plan to switch optics or remove the sight for transport, look for mounts with quick-detach mechanisms. These let you remove and reattach the red dot without losing zero. I found that quick-detach mounts saved me a lot of time and hassle during shooting sessions.
Price vs. Quality
In my experience, spending a bit more on a quality mount pays off. Cheaper mounts often compromise on materials or precision machining, which can lead to loosening or misalignment. I balanced my budget with trusted brands that have positive feedback from other Mossberg 590 owners.
Final Thoughts
Choosing the right Mossberg 590 red dot mount made a huge difference in my shooting experience. I recommend taking your time to consider compatibility, durability, mounting style, and your specific optic before making a purchase. With the right mount, your red dot sight will stay secure and accurate, making your Mossberg 590 even more effective in the field or at the range.
