Important Facts About Reflex Sights
You should be able to guess the way a red dot reflex sight works based on the name.
The “reflex” part points out that the sight reticle is projected toward the objective lens and reflected into the shooter’s eyes.
To achieve that, the lens coating already receives specific tuning, so it only reflects the wavelength of light utilized by the sight illuminator.
Other wavelengths of light transmission would pass through without much difficulty.
As LEDs have a relatively narrow band output, they are excellent choices for an ordinary reflex sight illumination system.
Aside from that, certain reflex sights also utilize optical fibers, beta lamps, and other parts.
In most cases, a reflex sight could be classified into two types using the configuration criterion: head-up and tube.
The head-up type possesses one lens assembly. The reticle projection point is behind the lens (close to the shooter, far from the muzzle).
On the contrary, the tube type resembles rifle scopes due to its tubular body with a lens at each end.
Furthermore, the reticle projection point of a tube-type reflex sight is mounted off to the optic axis side.
Depending on weapon platforms and shooting habits, one of the sight configurations would prove superior to the other.
How to Zero Reflex Sights
Zeroing a reflex sight requires nearly the same techniques as with rifle scopes. You need to make windage and elevation adjustments.
All you have to do is set up a target at 25 meters or so, place your weapon on rest, and send rounds downrange.
After each shot, proceed to assess the point of impact, observe how far it is from your desired point of impact, and apply necessary adjustments.
Repeat the procedure until you are satisfied with the results.
In my experience, getting zeroed takes 3 or 4 tries of 2-3 rounds each. It’s a small price to pay for accuracy!
Besides shooting, you could zero the average reflex sight using a bore sight laser or even the gun’s original iron sights (if it’s appropriately zeroed).
Reasons to Get a Reflex Sight
Reflex sights are part of the electronic sight category, joining holographic and laser sights.
Sometimes, you can hear the red dot sight for the reflex sight in some experienced hunters.
It makes others think that reflex sight and red dot sight are twins!
A reflex sight is simply a dot through the reflecting glass, which shows an illuminated projection of the target in your view.
The red dot uses LED, which offers a bright aim picture.
The device can help you get quick target acquisition FASTER, and you can figure out your surroundings.
This is because you can use both eyes open. Most people often choose this regardless of this point when they have bad eyesight.
The available eye relief probably enhances your shooting accuracy aside from targeting abilities by many notches.
You can even aim your target in low light conditions and at night with a reflex sight.
It is outstandingly helpful in close-quarter sighting when the distance is minor than 100 yards.
However, they are still great at 300 yards, with lesser issues with their accuracy.
It’s important to note that reflex sights do not offer any magnification. You’re limited to how much you can naturally see through the sight.
Reflex sights are also more maneuverable and portable since they’re small and low-profile.
The construction is also rigid, which makes them ideal for tactical situations like CQB and home defense.
If reflex sights aren’t your style, you can check out my list of the best red dots under $100!
How to Choose the Best Reflex Sight for You
In that case, a reflex sight could become an excellent option if you want a huge amount of eye relief or want to take on multiple targets quickly.
Here are some of the ways I choose the best reflex sight for my needs:
#1 Rail Size
Rail size enables you to decide which sight is suitable for your gun. You can’t choose an extra-long scope if your rail sight is less than 6 inches.
Make sure to pick a sight that fits your rails.
Aperture will tell you which sights provide the best field of view.
These types of sights range anywhere from 30mm to 35mm. Spend time considering which one is the best red reflex under 100 for you.
Why does the weight of the sight impact the way you choose a reflex sight? It can determine how better or worse the sight matches your rifle and how you shoot.
You could get too tired to control your weapon when it’s too heavy, and your mind may stray from the main target.
There were times were I focused more on compensating for the weight of my scope than aiming at my target!
Instead, you should choose a product that has the proper weight for your hands. Do not just hear other users!
#4 Field of View
The field of view greatly supports your ability to observe and identify your prey quickly.
Your reflex sight should be able to adjust its reticle size to give you a wider, clearer field of view and sight picture.
Being waterproof is the first standard point to look for when checking the quality of a reflex sight.
In some current brands, the product also has other resistances such as shockproof, fog proof, weatherproof, etc.
#6 Battery Life
For each reflex sight, the battery is one of the MOST CRUCIAL criteria to consider!
You should know how much the battery can last with continuous use. Most flex sights use LED with minor energy consumption that can last more than 1000 hours.
You enable to bring a spare battery when using a new reflex sight.
Mostly, customers love getting a warranty when they purchase a product.
A guarantee is also a good symbol for the manufacturer to prove the quality of the product and a marketing method.
As a wise buyer, you should check the warranty policies.
Shooting with a Reflex Sight: Tips & Tricks for Beginners
1. Practice Makes Perfect
Generally speaking, a reflex sight substantially improves your shooting ability, but that doesn’t mean you could skip practice!
I’ve run through my fair share of sights, and I’m only as good as the last time I trained.
There is no substitute for firearms training, so if you are new to reflex sights, spend some time at the range.
The more time you shoot with your reflex sight, the more adept you get at using it, which is vital!
At all times, keep in mind that a reflex sight is simply an accessory. Their overall effectiveness is decided mainly by the ones that wield them.
So if you genuinely want to get the most out of your reflex sight, regular shooting practice is a MUST!
2. Keep Reticle Brightness Settings at an Appropriate Level
It goes without saying that if you don’t see the reticle, the reflex sight is not much of use.
Therefore, ensure that you keep an eye on the lighting condition in your vicinity and adjust the reticle brightness settings if needed.
Keep the illuminator intensity high in the sunlight and low in the dark to reach optimum performance with a reflex sight.
If you intend to pair your reflex sight with a night vision optic, it’s essential that the sight has suitable intensity settings.
Trust me; it gets difficult finding your reticle if all you can see is green through your NVGs.
Otherwise, consider putting a night vision monocular on your non-dominant eye and save the dominant eye for the reflex sight.
3. Take Things at Your Own Pace
The average shooter with a decent reflex sight should have little to no trouble landing shot after shot on targets.
Nonetheless, if you notice that your shot patterns resemble groups from a shotgun, there is a chance that you are throwing rounds way too fast.
Of course, it feels great to discharge as quickly as possible, but speed always reduces accuracy.
“Slow is smooth, and smooth is fast,” I’ve found.
As a result, if you don’t waste your ammo needlessly, slow down and ensure that each round hits where you want!
It’s not a contest here, so you have nothing to worry about. Take your time and fix your shooting tempo.
4. Pay Attention to the Sight
Most reflex sights on the market nowadays are rugged, especially those from reputable brands like Aimpoint and Trijicon.
Nonetheless, the sights remain delicate accessories, and mistreatment could cause unexpected failures in critical moments.
Whenever you bring your reflex sight to the field, don’t ever subject it to excessive vibrations and hard impacts.
Both the lens and the illuminator of reflex sights are prone to crack/malfunction, so don’t do anything extreme!
I’ve found that crashing into things really ruins your sights and your day.
Operation difficulties could be reduced somewhat if you manage to pick a reliable product, though.
5. Consider Mounting Backup Iron Sights
“My reflex sight performs admirably. Why bother setting up backup iron sights?” some might ask.
Well, it’s indeed true that as long as you don’t pull any stunts, your sight could remain in operation for quite some time.
However, it’s worth noting that you would be left without an effective aiming system around in case of failure.
In a hunting scenario, you’ll have to return to your camp and get a new sight.
You would feel much annoyed, but the situation is FIXABLE!
However, in a house invasion scenario, things would get dangerous facing armed robbers when you only have a sightless weapon.

Reflex Sights vs. Red Dot Sights
Novice shooters often ask themselves and their friends: “Reflex sight vs. red dot sight, which one is the better choice?”
To answer that question, you have to know that a red dot sight is not exactly a distinct type of sight.
It’s an umbrella term used to describe several optics types with a red dot as their aiming point.
In most cases, there are around three types of sight that belong to the red dot category: reflex sight, prism sight, and holographic sight.
To learn more, you can check out this comparison guide on red dots vs. scopes!
As mentioned above, the aiming reticle of a reflex sight is projected by an illuminator, which would then be reflected right back into the shooter’s eyes.
There are two types of reflex sights based on the configuration: head up (exposed) and tube.
Because a reflex sight has unlimited eye relief, you can position your head anywhere you like.
In addition, it’s possible to keep both of your eyes open while shooting with a reflex sight, which significantly improves situational awareness.
No matter what happens on the field, you would be able to reacquire the target in the blink of an eye!
Given that reflex sights are non-magnified optics, they work best in home invasion scenarios and tactical applications.
That being said, the versatility and flexibility of a reflex sight allow them to be used to good effect for various purposes.
I use them a lot in close-quarters shooting competitions.
Even if you are a shooter with average skill and less-than-perfect eyesight, reflex sights would never disappoint you!
Regarding the range, you could get magnifiers for your reflex sights to effectively engage targets at extended distances.
Certain reflex sights available on the market are battery-free, which means the battery life is no longer a concern.
Instead of using a series of lenses as with traditional scopes, prism sights rely on a prism to FOCUS on the target.
Because of that, prism sights are highly compact, but you need to deal with short eye relief and limited magnification.
Depending on the model, the reticle of prism sight could be either etched or illuminated.
The prism sight price tends to be higher in terms of cost than other types of red dot sight optics.
Nonetheless, the prism sight cost is also declining recently, so you could secure a quality example without burning a hole in your wallet.
Considering the characteristics of prism sights, they are reliable accessories for shooting at short to medium ranges.
Although the quick eye relief might give people trouble now and then, prism sights would still deliver EXCELLENT results.
Were you searching around for a tactical scope?
You should take a good look at what ordinary prim sights could offer. As virtually every prism sight possesses a built-in Picatinny mounting rail, installation is a breeze!
Finally, prism sights receive a lot of praise from shooters with astigmatism since these optics come equipped with diopter adjustment.
The majority of holographic sights you see nowadays come from EOTech and are well known for being extremely precise.
Essentially, the reticle of holographic sights is just a hologram sandwiched between the glass layers.
Once you turn on the sights, the integrated laser diode will illuminate the hologram through the collimating reflector and the holographic grating.
As their reticle size is tiny, holographic sights provide shooters with TOP-NOTCH accuracy all day long.
On the downside, holographic sights are more expensive than other types of red dot optics, so they are not in everyday use.
Generally speaking, if ACCURACY is your number one priority and you have money to spend, you should get holographic sights.
You could shoot with both eyes open like a reflex sight while using holographic sights, which permit you to monitor the vicinity with relative ease.
Military personnel and competitive shooters held holographic sights in high regard due to their precision. However, suppose you are shopping on a tight wallet.
In that case, there is no need to stretch your financial ability to the limit by buying holographic sights.
You could get up to 3 familiar reflex sights for the price of one holographic sight. I wouldn’t recommend it if you’re strapped for cash.
Frequently Asked Questions
Are Reflex Sights Good for Shooting at Close Ranges?
Due to the nature of reflex sights, people assume that such sights only do well at close range.
In reality, the accuracy issue is a little bit complex.
Overall, the precision of reflex sight should not deteriorate as the distance to the target increases.
Nonetheless, the sight effectiveness would decrease at a certain point due to the shooter’s eyesight or skill.
As a result, at long range, the accuracy of reflex sight in general inevitably suffers.
To preserve sight effectiveness while shooting at extended distances, it’s strongly recommended that you pair it with a high-quality magnifier.
Is It True That Reflex Sights Eliminate Parallax?
There is a common misbelief among novices that reflex sights are parallax-free, but the truth is far from that.
Sure, the reticle of most reflex sights is set to infinity, which limits parallax error.
Nonetheless, there is still some parallax presence around, mostly if you shoot at close range.
Therefore, it’s vital to put the parallax adjustment knob of the sight to use so you can overlay the reticle with the target.
Once that takes place, parallax error would likely have a negligible influence on your shooting accuracy.
Are There Any Brands That I Should Prioritize?
When you check a particular reflex sight and conclude that it suits your needs and requirements, you don’t have to care about its brand.
That being said, it’s a good idea to buy from well-known sight manufacturers on the market just to be on the safe side.
I recommend brands with excellent customer service and solid warranties.
The industry is highly competitive, and a brand would only be famous if it delivers quality products.
Although there is no guarantee that reflex sights from reputable names are free of defects, it’s much better than buying from lesser-known names.
Here are some names you should keep an eye out for Vortex Optics, Trijicon, Burris, Leupold, Ade Advanced Optics, and Aimpoint.
What Color Works Best for the Reticle of Reflex Sights?
Many reflex sights available for purchase nowadays offer red reticles, and the color red seems to be the standard choice for most shooters.
However, the color of the sight reticle is strictly a matter of preference.
If you don’t like red, you could go for green. The human eye is more sensitive to green than red, so you should spot green reticle patterns much easier in most cases.
On the other hand, a red reticle pattern often works great when shooting in a relatively greenish surrounding that contains trees, grasses, and foliage.
So to decide what color is suitable, take your situation into account.
My Reticle Washes Out. Do Brightness Settings Have Little Effect?
The majority of wash-out trouble could be dealt with by merely changing the reflex sight’s brightness settings.
If the reticle remains inadequate, consider installing a polarizing filter on your sight.
That should allow you to cut down the glare, and the reticle would present itself to you in no time.
There is also another way if you are in a hurry. That is to transform your reflex sight into a classic collimator sight temporarily.
Close the front lens cover and proceed to aim with both of your eyes open. As long as you have functional eyes, your brain blends the images. This is why I train to fire with both eyes open.
Now you could spot the aiming reticle under any lighting condition!
Purchasing the best reflex sight under 100 improves your hunting performance because your accuracy, shooting potential, and situational awareness could be greater.
You will get lost when you do not have a reliable review to understand a reflex sight, especially when the product has an affordable price.
Seeing as all of these products are on the affordable end of the scale, it’s easy to get caught up in how cheap they are and not look at their stand-out features.
Hopefully, my recommendations will help you select your suitable product!
