How A Rifle Scope Works

How A Rifle Scope Works

While it could look like it’s a breeze for seasoned users of a rifle scope to use one, it can be quite an intimidating task for someone who is not familiar with them. The one thing that makes the task of using one also a bit difficult for beginners is that these scopes come in different varieties.

The kind of scope you will need will depend a great deal on what you want to use it for. It is useful to learn how a rifle scope works.

What makes matters even more complicated is that no two rifle scopes are ever totally the same. This is the case even when we talk about rifle scopes manufactured by the same company.

What this means is that you will not be able to say that since you have already mounted a scope from the same company then you will be able to mount all the other scopes manufactured by this maker and get the same results.

The Parts Of A Rifle Scope

In order to understand how a rifle scope works, you need to start off by gaining a basic understanding of the parts that make this unit. The lenses are easily the most significant parts of your rifle scope. The bigger of the lens is known as the objective lens.

These are found on the end of your scope. They are the ones furthest from the stock of the rifle. Their function is to transfer light to the ocular lens.  The ocular lens is the lens that is closest to the eye.

There is a part of the scope where your objective lens is housed and it is called the objective bell. The section that houses your ocular lens is known as the eyepiece.

Scopes Work Like Telescopes

The Rifle scope functions much more like a telescope. There is light that passes via the objective lens and it focuses on a specific point inside the scope. This light is them magnified from the focal point by the ocular lens.

The image you see when looking through the scope is essentially that light. There is also a part in rifle scopes known as a reticle, you may sometimes hear others calling it the crosshair. The main job of this part is to tell you where exactly your shot will go after you have pulled the trigger.

Setting The Scopes

Different scopes come with a number of settings that can help you to view your target at varying magnifications. You may discover that one scope can allow you to see your targets between 3 times to 9 times more than your normal vision would usually do.

What this means in practical terms is that the objects you look at using this particular scope will look three times bigger than it would if looked at with your normal vision. Such scopes take advantage of a built in feature known as the power ring.

In order to change the magnification on the scope, you will have to just turn the power ring.

Most Scopes Are Set At 100 Yards

When you buy your brand new scope you will probably discover that it is set at 100 yards. In simple terms, this means that when your aim is an object 100 yards away, it should be clear. Rifle scope users need to be careful when they switch the settings on magnification.

This could introduce the challenge of parallax error. This is a situation where the changes in the aim of the scope happen when there are any changes in the position of the shooter’s eye.

This can happen even if the rifle remains perfectly at the same position. When your own position shifts, it will start looking like the aim is off target.

There are a few other controls you will find on your rifle scopes such as windage and elevation. The windage is responsible for tweaking settings on the horizontal part of the scope while the vertical settings are adjusted by the elevation adjustment.

The body of your scope is known as the tube. Tubes for rifle scopes come in two main diameters: 30 mm and 1-inch. The reason why you need to know this dimensions is so that you deploy the right mounting rings when you set the scope on your rifle.

In short, this is how your rifle scope works. Of course, it is not easy to learn everything in theory but it is important to know the parts of the scope and what they do. When you have one in your hands, the process of getting used to it will be easier.
