As a gun user, mainly rifles and pistols, you certainly understand the importance of adjusting the rear sight. It is no coincidence that this operation is mandatory, requiring the user to perform it often.

So, which way to move rear sight? What you need to care about is not simply the answer to the above question, but also a series of important information related.

The article below will provide you with a series of such information.

Which Way To Move Rear Sight?

To move the rear sight, you need to prepare some equipment such as a hammer, screwdriver, and other specialized tools suitable for your sight.

Before you start using the above tools, you need to check your weapons and choose one of the two most basic methods.

One of the most significant advantages of this method is that it allows you to change and set yourself up, even if you don’t have too much experience.

Although it only requires basic skills, the process can be pretty time-consuming, so you can complete all of the steps below.

  • First, use the rifle to test shoot at the center of the target. In this step, you note the need to clamp the gun to the lens.
  • Next, check the result of the last shot. If the shot is below the target, you will have to move the rear sight low. Conversely, move your rear sight up if the shot is above the target.
  • When adjusting, you both need to check the front sight, which is another important note that you can’t ignore: during and after the adjustment.

The reason is that the relationship between these two types of vision is quite extraordinary. If your shot is below the target, you adjust the rear sight to low, and the front sight will move in the opposite direction.

However, raising the front sight too high will not bring many advantages because the front view should provide the best accuracy and feeling of use.

Therefore, in changing at the rear, you need to consider possible problems with the front sight to avoid the worst outcome.

Horizontal Adjustment

Similar to vertical adjustment, horizontal adjustment is not too complicated. You need to follow the steps below to complete the job yourself without the help of a team of experts:

  • First, use a tool to help fix and align the rifle to the vise.
  • Then align the target center and shoot.
  • Finally, it’s time for you to test your shot. If the shot is to the left of the target, you will need to move the rear sight to the right. Meanwhile, move to the opposite side if the one is on the right.

It sounds complicated, but if you have enough patience and practice regularly, the above operations will not be complex. If you are a beginner, you need to determine that it will take a lot of time to ensure the accuracy of the rear sight.

Step By Step To Adjust

To adjust the view, you will need to clamp the gun to the scope, review the result of the shot and determine the method of adjusting the aiming points.

To give you a better idea of ​​the tuning method, here are some accompanying guides and examples:

First, you need to familiarize yourself with some notation:

  • D1 is the length from the point of aim to the end of the impact.
  • D2 is the length of the ideal line of view you need to change.
  • R1 ranges from front view to target, and R2 is the length from front view to rearview.

Now, you can apply the calculation formula: D1/R1 = D2/R2.

For example, a rifle length from the front view to the rearview (R2) is 26.25”. 

The firing range (R1) is 1,800”, and the distance from the point of view (D1) is 5,3′‘, while the front blade is 0.505”.

To vary the height of the blade, using the above formula, you can calculate D2 by multiplying R2 by the result of D1/R1.

So, the ideal line of sight that you need to change is 26.25.(5.3/1.800)=0.077″.

After determining the ideal length based on calculations, it is time for you to practice choosing the adjustment method.

The method of determination has been described in great detail above. In this section, you need to consider some important rules below.

  • First, don’t point your weapon at any target you don’t have permission to or don’t intend to shoot at. Instead, having a target ready, or better yet, a target with a target, will make the determination more accurate.
  • Next, always make sure that the position where you put the gun is not at risk of injury or danger. In particular, when making adjustments, you must not ignore safety principles.
  • More importantly, don’t forget to learn the attributes of your vision and constantly seek to adjust accordingly.

For example, each type of viewfinder has different adjustment capabilities.

Some devices even support the adjustment of 1/4 or 1/2 inch or more, creating a moment with just a few simple steps. Understanding your weapon will allow you to make adjustments and changes quickly.


Once you have a clear understanding of how to move the rearview, it’s time for you to refer to the following series of commonly used information for more general and in-depth knowledge of the matter:

1. Is where you should put the alignment of your sight?

The front view should be in the rear binocular with an aperture viewfinder.

Meanwhile, with an open vision, it is better to determine the target direction and some other related issues with the rear sight’s notch.

2. Can you fire a gun without pulling the trigger?

Although it does not happen often, the gun can still fire without pulling the trigger. That’s why it’s essential to understand discharge prevention measures and other gun safety measures.

3. How far apart should flip-up sights be?

The farther the vision, the greater the accuracy. However, that is not to say that the best concept for all marksmen is the same.

For example, some people will be satisfied with the distance of 14.5” because it suits the shooting style, while others will love the field of view up to 18”.

4. Will Bullets explode in a house fire?

The above assumption can ultimately come true. For example, when a bullet is placed in a wildfire, it will automatically explode, scattering small shrapnel in all directions and can cause serious injury to those around.

5. Can you zero a red dot without shooting?

The answer is yes.

However, to achieve the above effect, you will need to perform every operation precisely as directed, combined with patience and regular practice.


Which way to move rear sight? The steps are not too complicated. Yet, if you are a starter, you have to invest time and effort to get the precision.
