The good news first. Both EOTech and Aimpoint are leading manufacturers of shooting optics. They have fantastic sights to offer.
The bad news? They are quite expensive, and if you own more than one AR or another rifle that you’d like a red dot sight on, it’s quickly getting prohibitively expensive to own multiple of these sights.
Other disadvantages are that any red dot sight is useless if you run out of battery. Optical scopes don’t need batteries and thus have a clear advantage when it comes to that.
These kinds of sights also typically don’t have any optical magnification. They come in standard 1x and therefore are harder to use on longer distances. They are best used by themselves for tactical situations including combat, survival, self-defense, etc.
EOTech vs Aimpoint Comparison
Both Aimpoint and EOTech provide high-end red dot sight solutions. They are ridiculously sturdy and often used by military and police because they are close to indestructible. Private persons deploy them for a variety of uses including survival planning, self-defense, shooting on the range as well as hunting.
EOTech is based in the United States while Aimpoint is a Swedish company.
Choosing a riflescope can take a lot of research, trial and error, and time. The biggest question many people have when deciding what type of scope to buy is: what kind of optics should I be looking for?
For many close-quarter shooters, the red dot holographic sight as designed and produced by EOTech is their go-to optic. These scopes often have no magnification but feature easy target acquisition and durability. Two leading manufacturers in this type of rifle scope are Aimpoint and EOTech.
Comparing EOTech and Aimpoint
EOTech is part of L3 Technologies which is active in the national security and aerospace areas amongst a variety of other industries. Aimpoint, on the other hand, was started in 1974 with the goal to increase shooting accuracy.
And boy, that they did. Aimpoint was the first company to have a functional red dot sight that was usable. These quickly became the Pro-forma standard for red dots in the military, law enforcement, and pretty much any other shooting applications around the globe.
EOTech today offers a variety of red dot scopes including magnifiers and accessories. Lately, they also have started to produce optical scopes including variable scopes for a diverse range of shooting and hunting uses. Their red dots are widely used in military and law enforcement today.
The first sights by EOTech were nothing short of revolutionary. Until then all sights were round. The design introduced was a square glass with a reticle that was unique. Today, there are quite a few EOTech clones you can find in case you want to get a sight that is more affordable. These usually have fewer capabilities than the original and in many cases are not holographic sights.
Over the years Aimpoint has introduced a range of red dot sights. The M4 is one that is widely used in military outfits. They have also started to offer lower-priced sights. These are by no means cheap but are somewhat more in reach for many shooters.
Aimpoint sights are often the preferred choice for law enforcement units worldwide. They are very durable and nearly indestructible. One of their main advantages is the ridiculously high battery life which often reaches over 50,000 hours before you are required to change the battery.
Similar to the EOTech sights, there are also quite some Aimtech clones available for purchase. They are cheaper and usually not as dependable, but they do the job for recreational uses.
EOTech 512 vs. Aimpoint Pro
The Aimpoint Pro and EOTech 512 are moderately priced holographic red dot sights. They are comparable in many ways, but there are a few features of each scope that may sway your opinion on which scope to buy.
At first glance, the stereotypical reasons for one or the other are the usual. The Aimpoint has an excellent battery life, is waterproof, and easy to use. The EOTech sight, on the other hand, is more affordable, has more reticle choices, has a smaller dot for long ranges, and has the more transparent glass. So, do we have a clear winner yet? Clearly not. Let’s dig a little deeper.
Both Aimpoint’s and EOTech’s weapon sights have advantages and disadvantages over the other. The most known fact about the Aimpoint is that they offer an immense battery life.
You can expect it to run around five years without having to change the battery. Besides that, the Aimpoint sights are pretty much indestructible which is excellent if you use it in rough environments.
The outstanding feature of the EOTech is the fast target acquisition and the tremendously helpful holographic 3D reticle. They offer a fantastic view of the target with no obstructions.
The EOTech uses a laser and projects a red dot onto a holographic lens. This produces a 3D view of the target giving the shooter unparalleled accuracy and visibility.
Aimpoint uses a LED to produce the red dot on the reticle. The dot might be slightly less sharp, but an LED requires a lot less battery juice compared to a laser. This is where the difference in battery life comes from between both of these sights.
Technical Specifications of the Aimpoint Pro vs EOTech 512
Those without a lot of time on your hands, here is a quick rundown of comparable features on both the Aimpoint Pro and the EOTech 512 model. Both the Aimpoint and EOTech sights have several differences in their specs as you can see below:

As you can see, there are clear differences between the EOTech vs Aimpoint sights. Let’s have a closer look at the features that the EOTech and the Aimpoint provide the shooter.
Display – EOTech vs Aimpoint
The displays on both the EOTech vs Aimpoint optics are generous with their eye relief and parallax settings.
The Aimpoint Pro features no parallax settings. The eye relief is unlimited. This sight is designed for use in rapid fire scenarios.
The display on the Aimpoint model is designed for shooting with both eyes open. This feature enables the operator to have greater situational awareness than with sights that require single eye operation. Both eyes open also allow for higher speed when acquiring the target and provides a natural field of view.
Using both eyes for aiming increases the field of view tremendously and provides increased performance regarding target acquisition. All Aimpoint sights, including the Aimpoint Micro are designed to be used with aiming with both eyes. Overall, many modern red dots provide this capability.
One of the best features of the display on the Aimpoint Pro sight is the ability for the sight to activate even with the lens caps on. The lens caps on the sight are clear enabling the rifleman to sight a target, in an emergency situation, without having to worry about the lens covers. The lenses on the sight are still protected, but your targeting isn’t compromised.
The EOTech’s display utilizes an accurate heads-up display (HUD) that allows the user greater situational awareness. The sight can be used on multiple weapons and is not limited to carbines. Many people opt to mount the EOTech on their crossbow, bolt guns, and small-caliber machine guns.
The HUD on the EOTech model uses a laser to illuminate the red dot pattern embedded on the sight. This allows you to sight your target accurately, no matter the positioning of your eye in relation to the display. If you need highly adaptive sighting, the EOTech gives just that when shooting.
Best Sight: The Aimpoint Pro has a superior performance with the display. The “lens cap on” functionality that protects the lens and shooter is a great feature. Also, with dual eye focus, the Aimpoint Pro sight performs better
Aim Dot – Red Dot Sights
The Aimpoint Pro sight features a 2 MOA dot. Some other models of the Aimpoint lineup have an adjustable 2-4 MOA dot. There is a 1 MOA dot on the EOTech optic. The MOA ring goes from 0 to 68 and offers plenty of correction for the operator.
The Aimpoint sight can be a little funky when interacting with various background colors. This may be a preference. There are adjustments for the brightness of the sight. Once you adjust for your preferred brightness on the red dot, you should find that it corrects the transparency issues.
The EOTech is much smoother when sighting because it doesn’t react the same way that the Aimpoint scope does to the background color. This may have something to do with the overall construction style of the EOTech vs Aimpoint scopes.
Best Scope: It’s a wash and depends on how you prefer your aim dot to look. Since they are the same magnification and size, it is about personal illumination preference.
Night Vision Compatibility
The Aimpoint Pro is night vision device compatible. The lenses are coated to ensure that the reticle stays visible in the darkness.
The EOTech512 is compatible with night vision. EOTech recommends that you switch the scope to night vision mode before you use the optic in such conditions. Doing so avoids image saturation when using the scope in tandem with an NVD.
Best Optic: When it comes to night vision both scopes perform well.
The overall sizes of the two scopes are the same. Their weights are almost identical. The housing for the display is where the two scopes differentiate.
The EOTech sight housing is a thin box that almost disappears when sighting your target. It is easy to ignore the little metal box when you are looking towards your target.
On the other hand, the display housing on the Aimpoint is a little bulky. If you like a slim profile for your sight, the Aimpoint pro may not have what you want.
Best Gunsight: User preference is going to play a big part in this. The slim profile of the EOTech 512’s display housing makes it better for overall function.
Environmental Settings – Survival Mode
The usability of the scopes in various environmental conditions is vastly different. The Aimpoint Pro optic makes sure that you know that this scope is going to function, no matter what you put it through. The EOTECH 512 Holographic Weapon Sight lags considerably behind the Aimpoint Pro when looking at the operating conditions.
|Operable before and after aftershock.|
Limits: X-axis: 500 g, 0.7 – 1.1 ms (3 shocks), Y-axis: 40g ±4g, 11 ±1ms (2 shocks in each direction, Z-axis: 40g ±4g, 11 ±1ms, two shocks in each direction. Functional during exposure (room temperature)

** EOTech reached a $40 million settlement (2007) on the 512. This was because of zero shift that occurs with the sight when zeroed at ambient temperatures (79* F) and then used in a colder or hotter environment. These numbers are only the operating temperature that the sight will function in, not the actual operating temperatures of a zeroed weapon. Some EOTech 512 optics that reached a zero shift could never operate with an accurate zero again.
The difference in the environmental specs when comparing EOTech vs Aimpoint shows what each one values with performance. The Aimpoint Pro is specifically designed to take a beating. They use the smaller 3v battery to withstand shocks and vibration and not allow the sight to be interrupted.
The waterproofing on the Aimpoint Pro means that you could practically scuba dive with the scope on and it would still be functional. The 150-ft. depth of the Aimpoint completely dwarfs the EOTech’s 10 ft. submersion depth. For any amphibious firing conditions, the Aimpoint Pro is a superior choice.
The basic clear covers on the Aimpoint Pro are designed not only to protect the glass but to assist the operator when firing in intense conditions. They protect from water, sand, and a vast majority of chemicals likely to be found in a combat zone (lubricating oil, diesel fuel, hydraulic oil). The EOTech 512 doesn’t have any chemical resistance listed on its user manual. Because of the housing of the display, it appears that chemical interactions would disrupt the HUD.
Finally, we come to the temperature operating parameters of the two scopes. It is important to note that the settlement against EOTech for faulty scope operation in harsh weather conditions was in 2007. There doesn’t seem to be a significant reporting of additional issues since then. Unfortunately, this doesn’t alleviate the functionality issues that come with the use of the AA batteries within the scope EOTech has chosen to put inside their 512. The battery choice for the two scopes is the main difference in their temperature functionality in real-world conditions.
AA alkaline batteries have a working temperature of -30° C to 55 C (slightly higher for lithium). The 3v batteries that are the power source for the Aimpoint Pro Scopes have an operating temperature of -40°C to 125°C. While it is never likely that you will be operating in conditions of 125* C (because you would be dead), your scope may experience temperatures much higher than the physical environment.
The barrel friction from rapid-fire heats your weapon, the heat transfers to the scope that is mounted on the gun. This means that the temperature of the scope can rapidly change if firing in a cold environment. Also, in a hot climate shooting scenario, the temperature of the scope will go much higher than the ambient temperature.
The temperature range for the battery in use doesn’t seem like it should be a huge deal until you break down the usage. In this case, the use of an AA battery instead of a 3v stunts the performance of the EOTech 512.
Best Weaponsight: Hands down the Aimpoint Pro.
Battery Life – EOTech compared to Aimpoint
In addition to the operating temperature issue with the two battery choices, there is the question of battery life. There are striking differences between the EOTech 512 and the Aimpoint Pro.
The EOTech 512’s AA batteries have a battery life of 1,000 hours. There is an automatic shut off on the EOTech of 8 hours. In real-world situations, the automatic shut off can create problems (imagine being in the middle of a combat situation and your sight powers down). Many people insist on having a good iron sight on their weapon, and with the EOTech 512, it is a must for a worst-case scenario.
What is the best affordable red dot sight for AR-15?
In contrast to the EOTech, the battery life of the Aimpoint Pro is 30,000 hours. That is 3.5 years of always-on activity for the scope. There is no auto shut off and many users of the scope remember to change the battery on their birthday every other year or so. If you turn the scope off, the battery life increases dramatically.
Longest Battery Life: Aimpoint Pro has a superior battery and lifespan of always-on usage. This makes it more reliable when planning for survival and self-defense uses.
If you go line-by-line on features and specs for these optics, the EOTech 512 is a great scope for those who are not necessarily faced with life and death situations. The Aimpoint Pro is a superior weapon sight when in a combat situation. Those who need a weapon optic that they can count on to save their friends will choose an Aimpoint Pro.
That being said, the EOTech 512 is a great gunsight. It is just designed to function differently than Aimpoint’s optic. Many people will never see a combat situation and will enjoy the freedom of the display on the EOTech 512 (similar when you compare it to the EOTech 518). The slimmer profile and smooth operation make the 512 from EOTech an excellent choice for many marksmen.
Both sights illuminate the target with a red dot but use different technology to do so. EOTech uses a laser to paint the dot while Aimpoint uses a LED. The laser in conjunction with the holographic reticle provides a sharper image. The LED red dot optic on the other hand is robust and has much longer battery life. No matter which one of the red dot sights you choose, you can and should aim with both eyes open. Both optics offer night vision compatibility so you can combine them with a night vision device.
