What Is Parallax Error in a Rifle Scope and How to Adjust It?
What Is Parallax In A Rifle Scope?
When you’re shooting a rifle, you want to make sure that your bullet hits where you’re aiming. But if your scope is misaligned, your bullet will land in a different spot than you intended. One of the most common causes of scope misalignment is parallax error.
Parallax error occurs when the object you’re aiming at and the crosshairs in your scope are not in the same focal plane. This can happen if your head is not positioned correctly behind the scope, or if the scope is not properly mounted on your rifle.
In this article, we’ll explain what parallax is, how it can affect your shots, and how to correct parallax error. We’ll also provide some tips on how to choose a scope that is less prone to parallax error.
So if you’re ever wondering why your shots aren’t hitting where you’re aiming, parallax error may be the culprit. Read on to learn more about this common problem and how to fix it.

| Parallax | The difference in the apparent position of an object viewed along two different lines of sight, as seen from different positions. | When you look at a tree through a rifle scope, the top of the tree appears to be in a different position than the bottom of the tree. This is because your eye is not directly in line with the scope’s objective lens. |
| Causes | Parallax is caused by the difference in the distance between the object being viewed and the objective lens of the scope. | The closer the object is to the scope, the greater the parallax. |
| Effects | Parallax can cause the point of impact of the bullet to be different from the point of aim. | If you are not aware of parallax, you may miss your target when shooting. |
Parallax is a common problem that can affect the accuracy of a rifle scope. It occurs when the shooter’s eye is not aligned with the optical center of the scope. This can cause the point of impact of the bullet to be different from where the shooter is aiming.
In this article, we will discuss what parallax is, how it can affect the accuracy of a rifle scope, and how to correct it. We will also provide some tips for choosing a rifle scope that is less susceptible to parallax error.
What is parallax?
Parallax is the apparent displacement of an object caused by a change in the observer’s position. In a rifle scope, parallax is the difference in the point of impact of the bullet when the scope is aimed at a target at different distances.
This can be caused by a number of factors, including:
- The position of the shooter’s eye: If the shooter’s eye is not aligned with the optical center of the scope, the point of impact will be different.
- The position of the target: If the target is not located directly in front of the shooter, the point of impact will be different.
- The design of the rifle scope: Some rifle scopes are more susceptible to parallax error than others.
How to correct parallax in a rifle scope?
There are a number of ways to correct parallax in a rifle scope. The most common way is to use a parallax adjustment knob. This knob is located on the side of the scope and can be turned to adjust the point of impact for different distances.
Some rifle scopes have a built-in parallax correction system that automatically adjusts the point of impact for different distances. These scopes are often more expensive than scopes with a parallax adjustment knob, but they can be more convenient to use.
Other ways to correct parallax include using a range finder or by estimating the distance to the target.
Tips for choosing a rifle scope that is less susceptible to parallax error
When choosing a rifle scope, there are a few things you can look for to minimize parallax error. These include:
- A scope with a large objective lens: A larger objective lens will provide a wider field of view and make it easier to align the scope with the target.
- A scope with a long eye relief: A long eye relief will allow the shooter to move their eye back from the scope without losing focus.
- A scope with a built-in parallax correction system: A built-in parallax correction system will automatically adjust the point of impact for different distances.
By following these tips, you can choose a rifle scope that is less susceptible to parallax error and improve the accuracy of your shots.

2. What is parallax in a rifle scope?
Parallax is the apparent difference in the position of an object when viewed from two different positions. In a rifle scope, parallax is the difference in the point of impact of a bullet when the scope is aimed at a target at different distances.
Parallax error is caused by the fact that the objective lens of a rifle scope is not located at the same point as the eyepiece. This means that the image of the target seen through the scope is not in the same plane as the target itself. When the shooter’s head moves, the image of the target appears to move in relation to the crosshairs, causing the point of impact to shift.
The amount of parallax error depends on the distance between the objective lens and the eyepiece, the distance to the target, and the angle of the shooter’s head. The greater the distance between the objective lens and the eyepiece, the greater the parallax error. The greater the distance to the target, the greater the parallax error. And the greater the angle of the shooter’s head, the greater the parallax error.
3. The effects of parallax on accuracy
Parallax error can significantly affect the accuracy of a rifle shot. The greater the difference in the point of impact at different distances, the greater the parallax error. Parallax error can cause a bullet to miss the target by several inches or even feet.
For example, if a rifle scope has a parallax error of 1 inch at 100 yards, a bullet fired at a target 100 yards away will hit the target 1 inch below the point of aim. If the same rifle scope is used to shoot at a target 200 yards away, the bullet will hit the target 2 inches below the point of aim.
Parallax error can be a major problem for long-range shooting. However, it can be minimized by using a rifle scope with a built-in parallax correction system or by using a range finder to estimate the distance to the target.
4. Tips for avoiding parallax error
There are a few things that you can do to avoid parallax error when shooting a rifle.
- Make sure that your eye is properly positioned in the scope. The eyepiece of a rifle scope should be located at the same height as your eye. If your eye is too low or too high, you will experience parallax error.
- Keep the target and the rifle scope as steady as possible. The more movement there is in the rifle scope, the greater the parallax error.
- Use a rifle scope with a built-in parallax correction system. A parallax correction system allows you to adjust the scope so that the point of impact is the same at all distances.
- Use a range finder to estimate the distance to the target. Knowing the distance to the target will help you to correct for parallax error.
By following these tips, you can minimize the effects of parallax error and improve your accuracy when shooting a rifle.
Parallax is a common problem that can affect the accuracy of a rifle shot. However, it can be minimized by using a rifle scope with a built-in parallax correction system or by using a range finder to estimate the distance to the target. By following these tips, you can improve your accuracy and hit your target every time.
What is parallax in a rifle scope?
Parallax is the apparent displacement of an object when viewed from different positions. In a rifle scope, parallax error occurs when the reticle is not aligned with the center of the objective lens. This can cause the point of impact of the bullet to be different from the point of aim, which can lead to missed shots.
How does parallax error occur?
Parallax error occurs when the eye is not positioned directly behind the center of the objective lens. This can happen if the shooter’s head is not properly supported or if the scope is not mounted correctly. Parallax error can also be caused by the shooter’s body or clothing moving during the shot.
How can I reduce parallax error?
There are a few things you can do to reduce parallax error:
- Properly support your head. Make sure that your head is properly supported so that your eye is always positioned directly behind the center of the objective lens. You can do this by using a cheek rest or by resting your head on the stock of the rifle.
- Mount the scope correctly. The scope should be mounted so that the center of the objective lens is in line with the bore of the rifle. You can have a gunsmith do this for you, or you can do it yourself if you are comfortable with working on firearms.
- Avoid moving your body or clothing during the shot. Make sure that your body and clothing are still during the shot. This will help to ensure that the point of impact of the bullet is consistent with the point of aim.
What are the symptoms of parallax error?
The symptoms of parallax error include:
- Missed shots. If the point of impact of the bullet is different from the point of aim, you will likely miss your target.
- Inconsistent shot placement. Even if you are able to hit your target, the point of impact may vary from shot to shot. This can make it difficult to make accurate shots.
- Frustrating shooting experience. Parallax error can be frustrating because it can make it difficult to hit your target and improve your shooting skills.
How can I fix parallax error?
If you are experiencing parallax error, there are a few things you can do to fix it:
- Reposition your head. If your head is not properly supported, you may be experiencing parallax error. Try repositioning your head so that your eye is directly behind the center of the objective lens.
- Remount the scope. If the scope is not mounted correctly, it may be causing parallax error. Have a gunsmith or qualified individual remount the scope so that the center of the objective lens is in line with the bore of the rifle.
- Purchase a scope with a parallax adjustment. Some scopes have a parallax adjustment that allows you to compensate for parallax error. If you are unable to fix parallax error by repositioning your head or remounting the scope, you may want to consider purchasing a scope with a parallax adjustment.
What is the difference between parallax and focus?
Parallax and focus are two different concepts that are often confused. Parallax is the apparent displacement of an object when viewed from different positions, while focus is the sharpness of an image. In a rifle scope, parallax error can cause the point of impact of the bullet to be different from the point of aim, while focus error can cause the image of the target to be blurry or unclear.
How can I prevent parallax error and focus error?
To prevent parallax error and focus error, you should:
- Properly support your head.
- Mount the scope correctly.
- Use a scope with a parallax adjustment.
- Focus the scope on the target.
By following these tips, you can help to ensure that your rifle scope is properly aligned and that you are able to make accurate shots.
parallax is a common problem that can affect the accuracy of a rifle scope. It is caused by the difference in the point of aim between the objective lens and the eyepiece. This difference can be minimized by adjusting the scope’s parallax setting. However, it is important to note that parallax cannot be completely eliminated.
When choosing a rifle scope, it is important to consider the type of shooting you will be doing and the distance at which you will be shooting. If you will be shooting at targets that are close to you, you will need a scope with a low parallax setting. If you will be shooting at targets that are far away, you will need a scope with a high parallax setting.
Parallax is a complex topic, but it is important to understand how it can affect the accuracy of your rifle scope. By understanding parallax and how to adjust for it, you can improve your accuracy and make more confident shots.
