Whether you are using a shotgun in a tactical situation or even certain types of hunting scenarios such as turkey or using slugs to hunt deer, a reflex sight or red dot sight can really make a difference.

In this article, we are going to point out at what aspects make the best red dot as well as reflex sights for shotguns. We will then take a look at our four picks of the best red dot sights for shotguns that outperform all the other options on the market.

We hope that by the end of this article, you will have a better idea and appreciation for shotgun optics and how they can be used to your advantage in both tactical and hunting situations.

Shotgun Optics Buyers Guide

  • Durability: When you are planning on utilizing a reflex sight for shotguns or a red dot shotgun sight, chances are the application you have for your firearm requires pretty heavy loads that produce a good deal of recoil.
    A lot of these sights use electronics, and it is important that your sight is built to absorb this recoil without losing function or knocking off your zero setting, especially when using slugs or a choke producing a tight pattern. If you’re shooting loads with a wide spread pattern, holding zero is not much of an issue. All of the sights on our list are built to withstand punishing recoil load after load.
  • Lenses: One of the main purposes of these sights is not just to provide more accuracy but also to provide the ability to have a more clear picture in low light settings. You want lenses that have been treated to allow maximum light transmission and also be able to resist scratching and abrasion.
  • True 1X: For just about all shotgun purposes you are not taking shots at anything over 100 yards. If you are and are successful, please let us know what you are using. These sights are designed to give you more precise aiming and ability to shoot in various light conditions more accurately.
    They are also designed to allow you to shoot while keeping both eyes open, which is a common component of a true 1X sight. While not as important for hunting scenarios, this is a must for shotgun sights used on tactical rifles.
  • Red dot: Whether you are using a true red dot, reflex, or holographic sight it is important that the reticle is clear and crisp throughout the range of brightness settings. Having a blurry reticle detracts from the intended benefits of these shotgun sights. On top of this, you should be aware of the range of brightness settings that are available. Being able to fine tune the brightness settings quickly in the field can be very beneficial. You should also be aware of the battery life on these scopes and keep a rough estimate on how much life you have used. The best sights are going to have a battery life that lasts hundreds of hours, but it is also up to you to manage as well. Some scopes will have automatic shutdowns or other technology to help conserve battery life and can end up saving you quite a bit of money in the long run.

The 4 Best Shotgun Red Dot Sights

It’s easy to lose track with the countless of different options and products you can find online or in your local store. Manufacturer’s descriptions always sound promising and apparently every one of them offers the best sight on the market. To make your final decision easier we point out 5 great options down below and let you know what we like about them.

Bestsight 1x40mm Red Dot Scope

If you’re looking for a solid, dependable red dot for your shotgun without breaking the bank, you should check out this offering from Bestsight. 

Its no-nonsense sturdy build (anodized aluminum alloy) and lens quality stands up to its pricier competitors. The 40mm objective lens delivers excellent resolution and handles low light conditions well. 

You can select from 5 brightness levels and cycle between green and red reticles, which makes this scope a good choice for home defense and CQB. You may prefer the green reticle for day shooting too as it’s easier to see and therefore reduces stress on your eye.

It delivers true 1x magnification suitable for home defense, enabling a fast sight picture on up-close and fast-moving targets. Importantly, the rails (11 or 20mm weaver compatible) and lens casing are ‘anti-seismic’ which means the scope can withstand the shotgun’s recoil, is dust/waterproof, and maintains its zero. 

We were surprised the scope didn’t ship with its 3V CR2032 lithium battery but for this price, it wasn’t a big deal picking one up at a local Walmart for a couple of bucks.  

The Bestsight is rugged, dependable, and affordable. It ticks the boxes for a tactical shotgun scope. Its rheostat-controlled brightness and green dot also makes it a decent companion for turkey season. 

Pros
  • Affordable
  • Compact, strong optics
  • Green/red reticles
  • Fast target acquisition
Cons
  • Only 1x magnification
  • batteries not included
 

SIG Sauer Romeo 5

Sig Sauer Romeo 5 sideview

The SIG Sauer Romeo 5, and the Romeo series of red dot sights in general, provide you with some of the best value for any red dot sight on the market today. That’s because these sights are very inexpensive in comparison to other competing sights, and yet are highly durable, very bright, adjustable, and provide you with excellent value for the money.

This is a 2 MOA Red Dot. It’s designed to fit to any Picatinny rail system, and is very robustly built. It has a waterproof rating of IPX-7, which is higher than many competitors.

That all being said, this red dot is actually not built by SIG Sauer, but is built by Holosun (SIG Sauer contracts Holosun to build the sight for them).

One of the most notable aspects and feature about the SIG Sauer Romeo 5 is the fact that it comes with Motion Activated Illumination. So long as the sight is turned on, it will turn off on its own after a long period of stillness. However, when it senses motion (such as when you pick up the rifle with the sight attached), it will automatically reactivate.

This feature is very beneficial because it means you don’t have to worry about turning the sight on and off. Just keep the sight on, and the red dot sill shut off after a period of inactivity in order to conserve the battery life (which can last for more than 40,000 hours) for as long as possible.

Take note that the motion activated illumination system will not work when the sight is turned off, so you need to make sure that it’s always turned on for it do so.

This sight also ships with a Co-Witness Riser Mount, to help clear plenty of space so you can still view your open sights or flip up sights through the scope. In other words, you can keep the red dot turned off and still line up the rear sight of your rifle with the front sight through the sight picture.

If you are in need of a high quality, bright, adjustable, and durable red dot for your semi-automatic rifle, but without spending a fortune as you would with an EOTech, then the SIG Sauer Romeo 5 is one of the best options on the market today.

Pros
  • Multiple Brightness Settings

This scope is also extremely easy to install and can fit directly on any Picattiny and Weaver style rails.

We really like the windage and elevation adjustments that can be made if you know you are going to be taking shots at increased distances and they are both clearly labeled. While you have to have a coin or other tool to make the adjustments, they hold very well. This scope holds its zero as well as any other scope on our list and will not be knocked off during normal use of the scope/firearm.
The battery life on this shotgun optics is extremely long, and it features an auto- reticle shutdown that helps to conserve battery life.

Pros
  • Excellent reticle illumination
  • Extremely rugged and weather resistant
  • Fast target acquisition
  • Holds zero
Cons
  • Takes up a lot of rail space

This shotgun red dot sight is built to perform in any situation and you don’t have to worry about this scope holding up to bumps, scrapes, or recoil that a working shotgun and optics go through with its aluminum construction and hard anodized finish.

Conclusion

So, we now come to the point where we must choose our pick for the best shotgun red dot sight. While all of these sights are great options, we give the edge for the best red dot sight for shotguns to the Aimpoint Micro T-2 Sight. Whether you are using it for tactical or hunting purposes, the T-2 provides all the necessary aspects of a superior red dot shotgun sight. However, it does cost a pretty penny. If you want something that does the job for a fraction of the price we recommend the Bestsight 1x40mm Scope.

So, whatever application you have in in mind for your tactical or hunting shotgun, we hope that this article has shown the benefits of shotgun red dot sights and shotgun reflex sights.

While they are not perfect for all hunting applications, they can be the missing link to more successful turkey and deer hunts, and regarding tactical scenarios, it’s almost a crime not to have one of these sights mounted to your 12 gauge.

  1. FYI. The TRS-25 cant handle defensive 12 ga. loads. The front lens on mine popped out from recoil within 7 rounds of 2 3/4″ slug and 00. So much for the gasses inside the sight. Shoots birdshot fine. Predicting 3″ would flip it out in round 1 or 2. My experience. I contacted Bushnell…no response. Granted, it was by email only.
