What to Look For in Your Shotgun Sights
Choosing the right sight for your shotgun is a different ball game compared to picking one for a rifle. The violent, shoving recoil of a 12-gauge is a brutal test for any piece of gear. You need something that can take a serious beating and keep on working. I’ve learned that the best shotgun sights are built like tanks and have features that complement the unique way we use shotguns, from home defense to turkey hunting.
The first thing I always consider is durability. Is this thing built to survive my shotgun? Look for sights made from aircraft-grade aluminum or similar robust materials. They should be fully waterproof, fog-proof, and shockproof. A warranty is a great sign of the manufacturer’s confidence. If a company offers a lifetime guarantee, they probably build their sights to last one.
Next up is the mounting system. This is critical. A loose sight is a useless sight. Most modern red dots use a Picatinny or Weaver rail interface. I make sure the mounting hardware is solid and that the sight locks down tightly. For shotguns with a receiver that’s drilled and tapped, you might need a separate mounting plate. The absolute best setup for a fighting shotgun, in my opinion, is a low-profile mount that co-witnesses with your iron sights, giving you a backup if the electronics fail.
Then there’s the reticle itself. For a red dot, the size of the dot is measured in MOA (Minutes of Angle). A larger dot, like a 6 or 8 MOA, is fantastic for fast, close-range shooting. It’s easy to pick up quickly when you’re bringing the gun up to your shoulder. A smaller dot, like 2 or 3 MOA, is better for precision work at longer ranges, like when you’re using a rifled slug barrel. Holographic sights often have a more complex reticle, like a circle-dot, which can be incredibly fast for target acquisition. Battery life is another huge factor. I always lean towards sights with long battery lives (tens of thousands of hours) and motion-activated shut-off to save power.
Finally, think about the window size. A larger window gives you a bigger field of view, which can help with tracking moving targets. However, a bigger window often means a bigger, heavier sight. It’s a trade-off. For a home defense shotgun that lives in a closet, a larger window might be worth the extra bulk. For a hunting shotgun you’re carrying for miles, a smaller, lighter micro red dot might be the perfect choice. By weighing these factors—durability, mounting, reticle, and size—you can find one of the best shotgun sights for your specific needs.
Frequently Asked Questions
What is better for a shotgun, a red dot or a holographic sight?
This is a classic debate. Both are excellent options, but they have different strengths. Red dots are generally more affordable, have incredibly long battery life, and are often more compact. Holographic sights, like those from EOTech, typically have a wider field of view and a reticle that doesn’t blur if you have an astigmatism. For most users, a quality red dot is a fantastic and cost-effective choice. If budget is less of a concern and you want the absolute fastest sight picture, a holographic sight is hard to beat.
Can a red dot sight handle the recoil of a 12-gauge shotgun?
Absolutely, but only if it’s built for it. You cannot just slap any pistol or rifle red dot on a shotgun. The recoil impulse is brutal. You must choose a sight that is specifically advertised as being shockproof and rated for shotgun use. The best shotgun sights are tested to withstand thousands of rounds of 12-gauge recoil. Always check the manufacturer’s specifications to ensure it’s rated for your firearm.
Do I need a special mount for my shotgun red dot?
In most cases, yes. Many modern shotguns come from the factory drilled and tapped for a rail, but you’ll usually need to purchase that rail separately. The most common type is a Picatinny rail. Once the rail is installed, the sight mounts directly to it. Some shotguns, like the Mossberg 500/590 series or Remington 870, have a huge variety of aftermarket mounting solutions available, including low-profile mounts that allow you to co-witness with your iron sights.
What MOA dot size is best for a shotgun?
For the typical uses of a shotgun—home defense, hunting within 100 yards—a larger dot is often better. I prefer a 3, 4, or 6 MOA dot. The larger dot is very easy to see and pick up quickly in a high-stress situation. It also covers a target appropriately at close ranges. A very small 2 MOA dot can be precise for slug shooting, but it might be harder to find quickly during a fast, close-range shot. When reviewing the 8 best shotgun sights, you’ll notice a trend towards these medium-sized dots for their versatility.
Should the dot be visible with both eyes open?
Yes, one hundred percent. This is a fundamental advantage of red dot and holographic sights. You should always shoot with both eyes open. This gives you full situational awareness, better depth perception, and allows for much faster target tracking. With practice, your brain will superimpose the dot onto the target, making the shooting process incredibly fast and fluid. It feels strange at first, but it quickly becomes natural.
How do I zero a red dot on my shotgun?
The process is straightforward but requires a stable rest and some patience. First, secure your shotgun firmly at a bench rest. Aim at a target at your desired zeroing distance (25 yards is a common starting point). Fire a single, careful shot. See where the slug or shot pattern hit in relation to your dot. Use the windage and elevation adjustments on your sight to move the dot to where the shot landed. Fire another shot to confirm. Repeat this process until your point of aim and point of impact are the same. Remember, shotgun slugs drop significantly, so your zero distance is very important.
