Some facts about reflex sight

Operating Mechanisms Of Reflex Sights

You should be able to guess the way reflex sights work base on the name. The “reflex” part points out to the fact that the sight reticle is projected toward the objective lens and got reflected into the shooter eyes. In order 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 would pass through without much difficulty. As LEDs have a rather narrow band output, they are excellent choices for the illumination system of ordinary reflex sights. Aside from that, certain reflex sights also utilize optical fibers, beta lamps and so on.

The Configuration Of Reflex Sight

In most of the case, reflex sights could be classified into 2 types using the configuration criterion: head-up and tube. The head-up type possesses one lens assembly and 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 tube type reflex sights is mounted off to the side of the optic axis. Depending on weapon platforms as well as shooting habits, one of the sight configurations would prove superior to the other.

How To Zero Reflex Sights

Zeroing reflex sights require nearly the same techniques as with rifle scopes, you need to make changes to the windage along with the elevation setting. All you have to do is set up a target at 25 meters or so, place your weapon on a rest and send rounds down range. 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. Besides shooting, you could zero the averages reflex sight using bore sight laser or even the gun original iron sights (if it’s properly zeroed)

Reasons for purchasing a reflex sight

In fact, the reflex sights are the electronic sight category apart from 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 the target acquisition faster and you can figure out your surroundings. This is because you are able to use both eyes open. Most people often choose this regardless of this point (when they cannot own both good eyes).

The unrestricted eye relief probably enhances your shooting accuracy aside from targeting abilities by many notches. With a reflex sight, you can aim your target in the low light conditions and at night.

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 its accuracy.

One thing you should know about the reflex sight before buying is that it does not include any magnification power.

Reflex sights are even more endurable and movable than other scopes. They are simply portable in their shape and size. The construction is also tough that militaries can use in tactical situations.  

How to choose a reflex sight

If you need a tool which probably offers you with unlimited eye relief, then a reflex sight could become a great option for you. Basically, it is not difficult to pick the right one for your rifle

Rail size

Rail size enables to support you decide which sight is suitable for your gun. In the rail size, you will know the number of inches and dimensions smoothly.


Aperture might support you which sights will provide you the best field of view. It also ranges on these types of sights from anywhere from 30 to 35mm. Spend time to take into account which one is the best red reflex under 100 for you.


Why does the weight of the sight may impact on the way you choose a reflex sight? It can determine how better or worse the sight can match on your rifle and the way you shoot.

If it is so heavy, you are tired to control your weapon and your mind cannot stay focus on the main target. Instead, you should choose a product which has a true weight for your hands. Do not just hear other users!

Field of view

The field of view is a specification that you can see via the optic. This is a great point to support you observe the prey easily. Also, you enable to adjust the width of the reflex sight.


Waterproof is a first standard point to check the quality of a reflex sight. In some current brands, the product also has other resistances such as shockproof, fog proof, weatherproof, etc.

Battery life

For each reflex sight, the battery life is one of the most crucial criterions to consider. You should be aware of how much the battery can last with continuous use. Most flex sights use LED with minor energy consumption can last more than 1000 hours. You enable to bring a spare battery when using a new reflex sight.


Mostly, customers love warranty while looking for a product. A guaranty is also a good symbol for the manufacturer to prove the quality of product and a marketing method as well. As a wise buyer, you should check the warranty policies.

Shooting With A Reflex Sight: Tips And Tricks For Beginners

  • Remember That Practice Make Perfect

Generally speaking, reflex sights offer substantial improvements to your shooting ability but that doesn’t mean you could skip practice. There is no substitute for practice when it comes to firearms so if you are new to reflex sights, spends 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 reflex sights are simply accessories and their overall effectiveness is largely decided by the ones that wield them. So if you truly want to get the most out of your reflex sight, regular shooting practice is a must.

  • Keep The Reticle Brightness Appropriate

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 lighting condition in your vicinity and adjust the reticle brightness if needed. Keep the illuminator intensity high in the sunlight and low in the dark to reach optimum performance with reflex sights.

In the case you intend to pair your reflex sight with a night vision optic, it’s essential that the sight has suitable intensity settings. Otherwise, consider putting a night vision monocular on your non-dominant eye and save dominant eye for the reflex sight.  

  • Take Things At Your Pace

The average shooters 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 definitely feels great to discharge as fast as possible but speed always lead to reductions in accuracy. As a result, if you don’t waste your ammo needlessly, slow down and make sure that each of the rounds hit where you want. It’s not a contest here so you have nothing to worry, take your time and fix your shooting tempo.

  • Pay Attention To The Sight

Most reflex sights on the market nowadays are rugged, especially the ones that come from reputable brands like Aimpoint, 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. Operation difficulties could be reduced somewhat if you manage to pick a solid product though.

  • Consider Mounting Backup Iron Sights

“My reflex sight performs admirably, why bothers setting up back up sights?” some might say. 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 in case of failure, you would be left without an effective aiming system around. In a hunting scenario, it means that you have to get back to your camp and get a new sight. You would feel greatly annoyed but the situation is fixable. In a house invasion scenario, however, things would get dangerous facing armed robbers when you only have a sightless weapon.

Reflex Sight: Frequently Asked Question

  • Reflex sights are mostly good for shooting at close ranges?

Due to the nature of reflex sights, people tend to assume that such sights only do well at close range. In reality, the accuracy issue is a wee bit complex. Overall, the precision of reflex sight should not deteriorate as the distance to target increase. Nonetheless, at a certain point, the sigh effectiveness would decrease due to the eyesight or the skill of the shooter. As a result, at long range, the accuracy of reflex sight in general inevitably suffers. In order to preserve the 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 sight could completely 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, especially if you shoot at close range. Therefore, it’s very important to put the parallax adjustment knob of the sight to use so you could overlay the reticle with the target. Once that takes place, parallax error would likely have negligible influence on your shooting accuracy.   

  • Are there any brands on the market should I 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. The industry is highly competitive and a brand would only be able to become 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, Aimpoint,…

  • What color works best for the reticle of reflex sights?

A lot of reflex sights available for purchase nowadays offer red reticle and the color red seem 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 then you could go for green. The human eye is more sensitive to green compared to red so you should spot green reticle patterns much easier in most of the case. On the other hand, red reticle patterns often work great when it comes to shooting in a relatively greenish surrounding that contains trees, grasses, foliages,… So in order to decide what color is suitable, take your own situation into account.

  • My reticle washes out and brightness adjustments have little effect?

The majority of wash out trouble could be dealt with simply by changing the brightness setting of the reflex sight. In the case 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 and that is to temporarily transform your reflex sight into a classic collimator sight. Close the front lens cover and proceed to aim with both of your eyes open. As long as you have functional eyes, your brain would blend the images and now you could spot the aiming reticle under any lighting condition.    

Co-Witnessing: Definitions And Instructions

To keep it short, co-witnessing refer to the shooter ability to aim with either the optical sight or the iron sight at moment notice. The idea behind co-witnessing is straightforward: you would have a backup sighting system in case the primary one fails. People that mostly use reflex sight consider co-witnessing a vital issue as it permits them to go after their targets when sight failures occur. While shooting habits might cause changes in certain case, the principle of co-witnessing is more or less the same. Here is a quick guide on how to get standard reflex sights to co-witness.

  • Step 1: Secure Proper Iron Sights

Surprisingly, a large number of modern day commercial rifles come without their iron sights equipped. Therefore, it’s highly likely that one of the first tasks you must do to co-witness you reflex sight is to get iron sights. Pay attention to the height of the sight and the optic so you could co-witness them without much difficulty. In the case you are unable to find a good match, don’t worry because you could use riser/spacer to make up the differences. Keep experimenting until you feel that everything is up to your liking and then move on to the next step.

  • Step 2: Zero The Iron Sights  

After you get your hand on the iron sights, it’s time to zero them. In the case you already have a zeroed reflex sight in place, you could use it to assist with the zeroing of the iron sights. It worth noting even you manage to set up everything correctly, there is a chance that both of your sighting systems would not line up.  Such a situation is quite common when it comes to co-witnessing and you should not feel bothered by it. Once the iron sights are zeroed, you could start adjusting the reflex sight to make its aiming reticle fall in line with the iron sights.

  • Step 3: Move The Sights Around

For most of the time, you should keep the iron sight low so the reticle of the reflex sight is obstructed as little as possible. It’s generally unwise for you to place the reflex sight reticle right on the back of the front sight. In order to acquire targets, the aiming reticle needs to stay above the front sight. Additionally, the position of the reticle itself is of no consequence, the position of your eye is the decisive factor. That means once zeroed, the reticle of the sight could be at anywhere within the viewing area and it’s still your proper aiming point.

Reflex Sights Vs Red Dot Sight: What Are The Differences

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 red dot sight is not exactly a distinct type of sight. It’s an umbrella term that people use to describe up to several types of optic that have a red dot as their aiming point. In most of the case, there are around 3 types of sight that belong to the red dot category: reflex sights, prism sight and holographic sights

  • Reflex Sights

As mentioned above, the aiming reticle of reflex sights is projected by an illuminator which would then be reflected right back into the shooter eyes. There are 2 types of reflex sights base on the configuration: head up (exposed) and tube. Because reflex sights have unlimited eye relief, you could position your head anywhere you like. In addition to that, it’s possible to keep both of your eyes open while shooting with reflex sights too which significantly improve situational awareness. No matter what happens on the field, you would be able to reacquire target in a blink of an eye.

Given the fact 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 reflex sights allow them to be used to good effect in a variety of purposes as well. Even if you are a shooter with average skill and less than ideal eyesight, reflex sights would never disappoint you. Regarding the range, you could get magnifiers for your reflex sights in order to effectively engage targets at extended distances. Certain reflex sights available on the market are battery-free which mean the battery life is no longer a concern.

  • Prism Sights

Instead of using a series of lenses as with traditional scopes, prism sights rely on a prism in order to focus on to 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.

In term of cost, the price of prism sight tends to be higher than other types of red dot optic. Nonetheless, the prism sight cost is also on the decline recently so you could secure a quality example without burning a hole in your wallet.

Considering the characteristics of prism sights, they are solid accessories when it comes to shooting at short to medium range. Although the short eye relief might give people troubles every now and then, prism sights would still deliver excellent results. Searching around for a tactical scope? Then you should take a good look at what ordinary prim sights could offer. As virtually every prism sight possesses built-in Picatinny mounting rail, installation is a breeze. Finally, prism sights receive a lot of praises from shooters with astigmatism since these optics come equipped with diopter adjustment.

  • Holographic Sights

The majority of holographic sights you see nowadays come from EOTech and they are well known for being extremely precise. Essentially, the reticle of holographic sights is a just hologram sandwiched between the glass layers. Once you turn on the sights, the integrated laser diode would illuminate the hologram through the help of the collimating reflector and the holographic grating. As the size of their reticle is very small, holographic sights provide shooters with top notch accuracy all day long. On the downside, holographic sights are expensive compared to other types of red dot optics and that is why they are not in common use.

Generally speaking, if accuracy is your number one priority and you have money to spend, you should get holographic sights. Similar to reflex sight, you could shoot with both eyes open 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, if you are shopping on a tight wallet, there is no need to stretch your financial ability to the limit by buying holographic sights. You could get up to 3 common reflex sights for the price of one holographic sight.

Reflex Sights With Cracked Lens: What You Have To Do  

The lens of the averaged reflex sights needs to be curved and coated in order to properly reflect the reticle. Hence, once the lens of your sight is cracked, the only thing left to do is to get new sights.  Besides that, you could get in touch with the manufacturer and see if you are able to purchase lenses separately. If you are in luck, you should be able to get your sight back to work by getting new lenses. In the worst case scenarios, you just have to throw away your sight altogether even if other components still work. Nonetheless, if you are a pinch and have some Plexiglas sheets lying around, there is a method you could try.  

Important Note: Remember that the following guide should only be used if you need to your reflex sight back in action as soon as possible. If you have time to spare, it’s strongly recommended that you wait for new sights or replacemen tlens to arrive.

  • Step 1: Fabricate A New Lens

Use the sight cracked lens as template and proceed to cut out a piece of Plexiglas that has the exact shape or close to it. There is no need to rush the process, just take your time and trim the Plexiglas until the piece could fit snug into the frame.

  • Step 2: Glue The Plexiglas Piece

After you are satisfied with the Plexiglas, proceed to use hot glue to secure it. As it’s hard to adjust the lens later, make sure that you like the way the Plexiglas is orientated.

  • Step 3: Send Rounds Down Range  

It’s highly likely that the reticle would be much smaller compared to before but it’s kind of expected. The original lens of the reflex sight is concave to reflect a larger image of the aiming point to you. With a flat piece of Plexiglas, the reticle would be reflected exactly as it’s.  Head to the range and see if you could land some shot on targets with this improvised lens or not. It goes without saying that the Plexiglas lens itself is far from perfect but it would do in a pinch.

Final Words

Purchasing the best reflex sight under 100 is improving 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 get a solid understanding about a reflex sight; especially when the product has an affordable price. Hopefully, my above recommendations will help you select your suitable product.
