We’ll examine some of the latest products on the market and see how they stack up against one another. If you’re in the market for a new red dot sight for your firearm, you won’t want to miss this. So sit back, relax, and let’s get to the bottom of this parallax mystery.
Red dot sight basics
Red dot sights are a popular aiming device used by marksmen and firearm enthusiasts alike. They are characterized by their simplicity, consisting of only a single illuminated dot on the aiming plane. This dot is aimed by positioning it over the target, similar to iron sights. However, the use of a red dot sight offers several advantages over traditional sights, such as increased speed and accuracy.
- Minimal Parallax error: A parallax error occurs when the shooter’s eye is not aligned with the sight’s aiming axis, causing the target to appear to move with respect to the reticle as the shooter moves his or her head. In red dot sights,parallax error is minimal..
- Ease of use: Red dot sights can be used with both eyes open since they are usually mounted in such a way that the shooter’s eye can maintain a natural field of view. This greatly increases situational awareness and allows for rapid target acquisition.
- Unlimited eye relief: Unlike traditional scopes, red dot sights can be used with unlimited eye relief, meaning the shooter can maintain the same view of the target regardless of the distance between the gun and their eye. This makes them ideal for use in close-quarters combat and other fast-paced shooting scenarios.
Types of reticles
Red dot sights come in different reticle configurations, each designed for different types of shooting and environmental conditions. Here are a few of the most common:
- Standard dot reticle: The most common reticle, consisting of a single dot aimed at the target.
- Double-dot reticle: Similar to the standard dot, but with a second, smaller dot beneath the main reticle. This allows for easier sighting at longer ranges.
- Circle-dot reticle: Consisting of a circle with a dot in the center. This reticle is ideal for quick target acquisition in close-quarters scenarios but may obscure smaller targets at long range.
The importance of zeroing
One of the most crucial steps in using a red dot sight is zeroing it in. This involves adjusting the sight so that the reticle aligns with the point of impact on the target. This is typically done at a range of 25-50 yards, depending on the sight and the type of shooting being done. Zeroing should be done with the same ammunition, shooting position, and target distance that will be used in actual shooting scenarios to ensure maximum accuracy.
| Distance | Movement |
|---|---|
| 25 yards | 1 click = 1/4 inch |
| 50 yards | 1 click = 1/2 inch |
| 100 yards | 1 click = 1 inch |
Zeroing should be done in a controlled environment, such as a shooting range, to ensure maximum accuracy. Once the sight has been zeroed, it is important to periodically check the zero to ensure that it has not been altered due to shock, weather conditions, or other factors that can affect accuracy.
How red dot sights work
Red dot sights are popular sights among gun enthusiasts because of their fast target acquisition and accuracy. In general, a red dot sight is a type of optic that projects a reticle onto a lens, indicating the point of impact. But how do they work? There are two main types of red dot sights: holographic sights and reflex sights.
- Holographic sights use a laser diode to project a hologram onto a lens. When you look through the lens, the hologram appears to float in space, giving you a precise aiming point. Because the hologram is projected at a distance from the lens, there is no parallax error. This means that the reticle will stay on target no matter how you move your head. However, holographic sights tend to be larger, heavier, and more expensive than reflex sights.
- Reflex sights, on the other hand, use LED lights to project a reticle onto a lens. When you look through the lens, the reticle appears to be superimposed on the target. Because the reticle is projected onto the same plane as the target, there is some potential for parallax error. However, this can be minimized by keeping your head in the same position and using the sight at the correct distance from your eye. Reflex sights are generally smaller, lighter, and less expensive than holographic sights.
The importance of parallax-free design
Parallax error occurs when the reticle appears to move relative to the target when you move your head. This can be a problem with some red dot sights if they are not designed to be parallax-free. However, many modern red dot sights are designed with a parallax-free design, meaning that the reticle stays on target no matter how you move your head.
One way that red dot sights achieve a parallax-free design is by placing the LED or laser diode at the same optical axis as the lens. This means that when you look through the lens, you are looking at the same focal point as the reticle. Any movement of your head will not cause the reticle to shift relative to the target, resulting in more accurate shots.
Another way that red dot sights achieve a parallax-free design is by using an optical prism. A prism is a triangular piece of glass that can change the path of light. By placing a prism between the LED or laser and the lens, the light can be redirected to the same optical axis as the lens. This results in a reticle that appears to be on the same focal point as the target, even if you move your head.
| Pros of red dot sights | Cons of red dot sights |
|---|---|
| – Fast target acquisition | – Requires batteries |
| – Parallax-free design | – Can be expensive |
| – Greater accuracy | – Can be heavier and bulkier than iron sights |
| – Easy to use for beginners | – May not be as durable as iron sights |
Overall, red dot sights are an excellent option for many gun enthusiasts. With their fast target acquisition, greater accuracy, and ease of use, they are a popular choice for hunting, target shooting, and self-defense. When choosing a red dot sight, be sure to look for a parallax-free design and consider your individual needs and preferences.
Factors Affecting Red Dot Sight Accuracy

- Mounting location
Parallax Error
Parallax error occurs when the apparent position of the red dot changes as the shooter moves their eye behind the sight. This can cause the shooter to aim inaccurately, even if the red dot appears to be on target. The best way to eliminate parallax error is to use a red dot sight with a parallax-free design. Many modern red dot sights on the market are designed to be parallax free, but it is always a good idea to check the specifications before making a purchase.
Dot Size
The size of the red dot can also affect accuracy. A larger dot may be faster to acquire, but it can also obscure smaller targets. A smaller dot is better for precision shooting, but it may take longer for the shooter to acquire the target. Finding the right dot size for your needs is essential. Many red dot sights come with interchangeable dot sizes, allowing you to experiment and find the best option for your shooting style.
Mounting Location
Mounting location is another factor affecting red dot sight accuracy. The sight should be mounted as close to the bore axis as possible to minimize the distance between the barrel and the sight. This can help improve accuracy and reduce parallax error. Additionally, the mounting location should provide a comfortable position for the shooter’s eye to align with the sight. Experimenting with different mounting options can help find the ideal location for your red dot sight.
Conclusion

Understanding parallax error in red dot sights
Parallax error is a phenomenon that occurs when the shooter’s eye is not perfectly aligned with the red dot sight’s optical axis. This can cause the shooter to perceive the red dot as being off-center from the intended target. The greater the distance between the shooter’s eye and the optical axis, the greater the parallax error.
- Parallax-free red dot: A red dot sight that is parallax-free means that the point of aim and point of impact are always on the same plane, regardless of the shooter’s position behind the sight. This means that, regardless of the shooter’s eye position, the red dot remains perfectly aligned with the target. Parallax-free red dot sights are highly desired for their accuracy and ease of use, especially in competitive shooting scenarios.
- Parallax-corrected red dot: A red dot sight that is parallax-corrected means that the manufacturer has incorporated a mechanism to minimize the effects of parallax error. These red dot sights will often have an adjustable diopter or lenses that can be moved to correct for parallax error. While they are not completely parallax-free, they do reduce the effects of parallax error significantly.
- Impact of parallax error: Parallax error can have a significant effect on the shooter’s accuracy, especially at longer ranges. It can cause the shooter to aim incorrectly, leading to missed shots and poor scores. Parallax error can also make it harder to make consistent shots, as the shooter’s position behind the sight will vary each time.
Red dot sights that are designed to be parallax-free are often more expensive than those that are not. However, for shooters who demand high levels of accuracy and consistency, they are well worth the investment.
| Distance (yards) | Parallax error (inches) |
|---|---|
