The Allure of Red Dots on a Shotgun
Faster Target Acquisition
The world of firearms has seen a revolution in sighting systems, and the red dot sight stands at the forefront. These compact, battery-powered optics project a simple red dot onto the glass, allowing the shooter to focus solely on the target. No longer are you wrestling with aligning iron sights; simply place the dot on the intended impact point, and fire. The advantages are numerous, particularly when considering the Remington 870 platform.
Improved Accuracy
With both eyes open, the shooter can quickly acquire the dot and place it on the threat or the quarry. This is a dramatic improvement over traditional iron sights, which require the shooter to align three points: the front sight, the rear sight, and the target. In high-stress situations, or when seconds matter, this speed advantage can be crucial.
Reduced Eye Strain
Secondly, accuracy improves. The red dot sight eliminates the inherent parallax error present in iron sights, which can lead to shots hitting slightly off-target. The red dot allows for more precise shot placement, especially at closer ranges where shotguns are often deployed. This translates to better groupings and more effective results.
Versatility
Thirdly, the reduced eye strain contributes to all-around performance. Focusing on three points can be tiring. The red dot minimizes the visual effort, and the target is always clear, regardless of eye dominance or vision difficulties. This leads to improved accuracy over extended shooting sessions.

Navigating the Realm of Remington 870 Red Dot Mounts
Rail Mounts
The market is flush with options for mounting a red dot sight on your Remington 870. Each type offers different benefits, considerations, and installation methods. Understanding these variations is crucial for making the right choice. Rail mounts are perhaps the most common and versatile solution. They attach directly to the receiver or barrel of the shotgun, providing a stable platform for attaching a variety of accessories. The rail is generally Picatinny or Weaver compatible, meaning it can accommodate a wide range of red dot sights and other optics.
Top Rail Mounts
Top rail mounts sit on the top of the receiver. These are straightforward to install and provide a good sight picture. However, they might increase the overall height of the firearm. They are relatively inexpensive and easy to find.
Side Saddle with Rail
Side saddle with rail combinations offer a practical advantage. They provide an integrated shell carrier, holding spare ammunition close at hand. This can be a significant benefit for home defense or tactical applications. The addition of a rail on the top of the saddle allows you to mount your red dot sight.
Cantilever Mounts
Cantilever mounts are designed to extend the optic forward of the receiver, allowing for a longer sight radius and potentially better eye relief. They can be beneficial if you want to position your red dot further away from your eye for improved viewing comfort or if you’re using a longer sight with a longer eye relief requirement.
Receiver Mounts
Receiver mounts attach directly to the receiver of the shotgun. They offer a secure and stable mounting platform.
Drill and Tap Mounts
Drill and tap mounts require drilling and tapping the receiver to accept mounting screws. This is the most secure method, but it requires specialized tools and a level of expertise. Many gunsmiths can do this for you.
No-Drill Mounts
No-drill mounts, which often clamp onto the receiver, provide a simpler installation, as the name suggests. They often don’t require any alterations to your firearm. They are easier to install. However, their stability can vary, and they may not be suitable for the most demanding applications.
Matching the Pieces: Compatibility
Footprint Compatibility
When choosing a Remington 870 Red Dot Mount, keep in mind the interplay between your mount, the red dot sight, and your personal preferences. Different red dot sights have different footprints. The footprint refers to the pattern of screw holes on the bottom of the sight. Ensure that the mount you choose is compatible with the footprint of your chosen red dot. Popular brands like Aimpoint, Trijicon, and Holosun each have their own footprints. If you are unsure if they are compatible, confirm compatibility with your red dot sight prior to purchase.
Height Above Bore
The height above bore is another critical consideration. The distance between the center of the red dot and the bore of the barrel influences how much you need to adjust your point of aim to compensate for bullet drop at different distances. A mount with a comfortable cheek weld is often desired. Consider how the mount will affect the position of your head on the stock when aiming.
