Buying Guide: How to Choose the Best Reflex Sight for Shotgun
Now that you’ve taken a look at our recommendations, you might be wondering what’s the best reflex sight for you.
We’ve listed factors you should consider before buying the best reflex sight for your shotgun.
Reticle size is measured in MOA, or minute of angle. What size you need will depend on your shooting intentions.
The MOA will tell how much distance you’re able to cover. It also refers to the size of the dot, where a higher number means a bigger dot.
For perspective, 1 MOA is equal to 1 inch at 100 yards. Similarly, 4 MOAs will translate to covering 4 minutes of the angle at 100 yards.
Lower MOAs are useful for providing pinpoint accuracy on your target at longer distances. This is useful in competitions that have a small target.
Larger MOAs are better for shooting faster at close ranges but have less precision. Since the dot is larger, it will cover a broader area of the target.
There are two housing configurations for reflex optics: open and tube.
For open types, the optical window, which is the only optical element, doesn’t require aluminum alloy housing. This allows you to see the reticle through an open window.
The result is a more compact design and a wider field of view. This allows you to view the target and its surroundings, providing a tactical advantage.
But because of their design, you cannot use any filters or accessories on this type of sight.
It also has an exposed light path due to its heads-up display (HUD). This may be a disadvantage in case something blocks the path.
Tube types look similar to telescopic red dot sights because it has a cylindrical tube surrounding the optics.
Tube types are compatible with various accessories, such as optical scopes, filters, and protective covers.
Because of their tube enclosing, the reticle and dot will appear brighter even in broad daylight. This will improve the user’s accuracy and precision.
Which one is better? Both have their pros and cons, so it will depend on what you need.
Size & Compatibility
When choosing the best reflex sight, it’s important to consider if it’s going to be compatible with your firearm, base, and purpose.
Some models are compatible with all types of firearms. But some may not have the ruggedness to last a few rounds. Some may not fit at all.
In terms of mounts, some models include a Picatinny or Weaver mount in your purchase. Keep in mind that if your gun fits on a Picatinny mount, it will not fit on a Weaver rail.
If your order doesn’t include a mount, check how much it will cost separately. If you’re tight on budget, purchasing extra equipment may end up being more expensive.
Consider the compatibility with other accessories as well. For example, you might need two optics or a magnifier. Not all reflex sights are compatible with magnifiers, so make sure to double-check this.
Last but not the least, consider the size of the product itself. This refers to the bulk and weight of the reflex sight, as this will play a big factor in your success.
The majority of reflex sights use AA, AAA, or CR batteries. The battery lifespan can range anything from 2,000 to 50,000 hours.
The best battery would be the CR2032 battery, which provides up to 50,000 operating hours. This eliminates the need to carry around a spare battery.
Along with this, consider the battery cover or aluminum alloy housing. Some products have reported issues of battery covers being difficult to re-install.
There are some models that use solar energy as a backup. Select Trijicon models and the Holosun Ring Open Reflex Sight are some examples.
It’s important to choose a high-quality model as it is directly related to durability.
A reflex sight may have fancy features, but those features will be nothing if the product won’t stand the test of time.
Check if the product is water-, fog-, and shock-proof.
You probably won’t be jumping into the water with your firearm. But the waterproof feature will help during rainy or snowy days.
A waterproof product doesn’t mean it will be fog-proof as well. On days with heavy fog and mist, it’s entirely possible for your optic to clog up and disrupt your vision.
Lastly, shockproof refers to how well an optic will handle the recoil. Some products don’t hold zero well, and some might even end up having loose screws after a few rounds.
To check this, it’s best to check customer reviews.
If you’ve been looking at product listings online, chances are you’ve seen a handful of customer reviews that complain about counterfeit products.
The sad reality is that there are a lot of vendors that sell fake products of well-known brands.
Some are very crafty to the point that it’s difficult to tell them apart by appearance only. And you end up telling them apart once you start using it and the quality falls short.
Counterfeit products are more common for high-end brands such as Leupold, Aimpoint, Vortex, etc.
So how can you tell if a product is a knock-off? Here are a few tips:
- Check the manufacturing or shipping location: Let’s say the brand says their products are made in the USA, but the product listing states a different location. Chances are, it’s fake.
- Cost: If it’s priced unusually low, then it’s better to be suspicious. An exception is if it’s a used product, of course.
- Customer Reviews: This is probably the most reliable information. Check what previous buyers have said about the product.
The best feature is the one you need the most. What does this mean?
A reflex sight may have all these fancy technology and features. But at the end of the day, if it’s not something you need, then it’s useless.
So when buying a reflex optic, ask yourself: What features do I need?
Below is a list of features to consider.
- Windage & Elevation Adjustments: Some models allow you to adjust by hand, whereas others require you to use a separate tool.
- Brightness: Check how many options you need in terms of illumination. Along with this, check if you need night vision or automatic adjustments.
- Field of View: The best kind of optic will offer unlimited eye relief. A large field of view will help you view the target and its surroundings.
- Controls: Check if the optic uses a manual or digital control. Since many products are compact, sometimes the button can be located near the lens. This makes it difficult for making adjustments, especially if you’re in the middle of shooting.
When purchasing any item, an expensive product can be a dealbreaker.
The good news is that reflex optics are available in various cost ranges.
An expensive product doesn’t always mean it has a better quality. Instead, consider the various kind of features and see what’s the best one for you.
Along with that, check the warranty and return policy. Some manufacturers don’t offer one at all.
The upside is that most manufacturers offer a warranty but always double-check the details.
Does the warranty apply to the entire set or certain parts only? How long is the warranty valid for?
These are some questions to keep in mind, even if a manufacturer offers a “lifetime” warranty.
FAQs About Reflex Sights
#1 Is a Red Dot Sight the Same as a Reflex Sight?
No, it’s not.
A red dot sight is an umbrella term for all sights that use a red dot.
This means a reflex sight is one of the many types of a red dot sight.
The distinct characteristic of a reflex sight is that it uses LED to project the red or green dot onto its lens. The projected dot hits the lens, reflecting it back to your eyes.
#2 What Are the Advantages of Using a Reflex Sight on a Shotgun?
Reflex sights provide accuracy and speed while remaining compact and lightweight.
They help provide better accuracy as many models are designed to work both day and night. Plus, they can also cover a wide range of distances.
Many good models have a large viewing window. This way, you can open both of your eyes the whole time. In the long run, this causes less strain on your eyes.
Pinpoint accuracy also helps in acquiring a moving or faraway target. The red dot will put your target within the field of view for a more accurate shot.
They are also more affordable and lighter than prism and holographic sights.
Last but not the least, it has a long lifespan. The lifespan depends on the quality of materials and battery.
For the battery, lithium batteries, such as CR2302, can last up to 50,000 hours. Some models use solar power, making it more energy-efficient.
In terms of the materials, most, if not all, reflex sights are made with durable materials such as aluminum. With proper care, these will last you for years.
#3 Are Reflex Optics Better Than Iron Sights?
Yes. Why? Reflex optics are more accurate and reliable.
Iron sights have been around forever. Because of this, the design can be a bit outdated unless you’re a skilled shooter.
With iron sights, one has to imagine the point of impact on a target.
Chances are, you’ll be using only one eye to shoot as this is how iron sights are typically used.
Lastly, the aim point is nowhere near as accurate or visible. Reflex optics use LED technology, which can perform well in both daylight and nighttime.
In comparison, an iron sight, even if has a tritium or fiber optic, won’t be as visible or bright. This will be a disadvantage, especially for long-range shooting.
#4 Is a Red Dot Better Than a Green Dot?
A red dot allows a faster acquisition speed because it catches the eye faster. It also has a lesser chance of “blending” into the background.
In cold or freezing temperatures, a red dot will have no operational problems. But depending on your product, a green dot may not work at all.
Green dots also have their advantages. It’s easier to see in low light settings, such as nighttime. It doesn’t require a high brightness setting, so this can conserve battery power.
Green dots also cause less eye strain, making it more beneficial for those with astigmatism.
#5 Are Reflex Sights Good for Short or Long Range Shooting?
They are suitable for both short and long-range shooting.
For short ranges, it’s advisable to choose a bigger dot size.
For longer ranges, a smaller dot would work better. To achieve better precision, you could also zoom in using a magnifier.
But there are other factors to consider, such as the firearm used, dot size and type, and the skill level of the person.
With that being said, reflex sights are much better suited for a close-range if you’re using it without a magnifier.
#6 What Dot Size Is the Best for a Shotgun?
It depends on the condition you’re in and what you need it for.
If your target is at a close distance and you need speed, a bigger dot will suit you better.
If you need precision, it’s better to get a smaller dot. This comes handy in situations such as target shooting or hunting.
Here’s a quick rundown of dot sizes for your information:
- 1 to 2: Provides a very precise aiming dot, suitable for longer ranges. But people with eye problems may struggle to locate the dot.
- 3 to 5: Provides a clear and accurate dot, suitable for close and mid-ranges. Suitable for target shooting and self-defense.
- 6 to 8: Provides speed, suitable for close ranges. Suitable for handguns and shotguns. The larger dot also helps people with astigmatism.
If you’re unsure, your local gunsmith shop will provide a wealth of information depending on your need.
#7 How Do You Mount a Reflex Sight on a Shotgun?
Mounting a reflex sight will require Allen wrenches and Hex keys. If your package doesn’t include a Picatinny rail or Weaver mount, you can get it from your local gunsmith.
The installation method is slightly different for long and short guns.
A rifle, shotgun, carbine, and machine gun are all examples of long guns.
For long guns, it’s best to mount the optic on top of the receiver end of the rail. This provides more stability and balance.
Installing a reflex sight on a long gun is pretty straightforward. Once you have a rail, all you have to do is tighten the bolts and screws in place.
For short guns, it’s trickier.
Besides the tools listed above, you’ll also need a mounting plate. This mounting plate will replace the rear iron sight.
Instead of relying on the screws, it’s a smart idea to use a blue Loctite for extra stability.
A blue Loctite will allow you to replace or remove when needed.
On the other hand, a red Loctite is a permanent attachment, which won’t allow any adjustments in the future.
Once the sight is mounted, it’s a good idea to do a few test rounds. This will tell whether the screws are tight enough.
#8 How Do You Zero a Reflex Sight?
Also known as sighting in, zeroing means aligning the red dot with your firearm so that you can accurately aim at your target.
If you have used a rifle scope before, zeroing a reflex sight is similar to this.
When zeroing for the first time, it’s best to turn the optic off or ignore it. If possible, flip it down once it’s zeroed.
For the next step, follow the manufacturer’s instructions. Since each model is different, the information provided will differ.
For best results, make all variables as consistent as possible. This includes your firing position, the ammunition used, trigger control, and so on.
Fire at least three test shots. Take note of all the information you got from these rounds.
From there, check what kind of adjustments need to be made.
Repeat the process until you zero in.
Our buying guide should give you an idea which reflex sight is the best for you.
But if you’d like our two cents, these are our recommendations:
This sight checks all the marks. For starters, it’s versatile. It fits all firearms and can be paired with another sight if needed.
