How Do Scopes Work

Before you learn how rifle Scopes work? Initially, you must acknowledge the basic components of a rifle scope. Because once you understand these critical elements of the riflescope. It will expand your overall understanding of how rifle scopes work and also help you grasp absolute clarity. So first thing first, there are some significant parts in any rifle scope. And I am going to define each in the most realistic manner possible and briefly.

Significant Components of Rifle Scopes

Importance of an Objective Lens 

You can’t understand a rifle scope unless you understand how an objective lens works. Why? Because an objective lens is undoubtedly the most critical factor influencing the overall performance of a rifle scope. 

Although there are many functions of lenses, however, experts suggest that there are three most critical parts of an objective lens. In the beginning, it helps enable light to enter into the riflescope. Once you have done it. Further, it generates an image that the other optical elements will magnify. And finally, when it is in control of resolving the scope issue. 

What Is an Erector System? 

The erector structure looks like a small plastic or metal tube containing three or four components or optics. Depending on whether the imaging viewfinder has a variable or fixed depth of field, it has three important parts. The objective image’s primary magnification helps coincide the reticle with the vertical system of the picture. Since it erects or spins the image right-side-up, as the title suggests.

Wintage & Elevation Explained

Because the erector tube is fixed at one end and free at the other, the windage and elevation bolts assist this end while supplying motion or adjustment to the reticle to adapt the aiming point to the real impact of the Reticle. Here is how? In a riflescope, a reticle is for the aiming purpose in your viewfinder. To use a rifle scope reticle suitably, you must first concentrate it on your eye. Besides, the reticle substitutes the standard iron sight system found on rifles.

Ocular Lens

This lens undertakes the image’s supplementary and ultimate optical zoom and is essential to determine eye relief length.

The Operation of Scope 

A rifle scope works as the light passes through and beyond the objective lens. These lenses make the images go inside the internal lenses. These very lenses are Erector lenses, sometimes referred to as internal lenses. The job of these lenses is to send the picture to the right-side-up position. Finally, the ocular lens magnifies that image before sending it to your eye.

An Expert Perspective 

When newbies ask experts about how do rifle scopes work, their immediate response is always lenses. Lenses are the essential optics that play an integral part in the overall operation of a complete rifle scope. If you knew how these lenses function or how these lenses are different from each other, you would know how rifle scopes work.  

Why Lens Are Important 

The lenses are the most crucial aspects of a rifle scope. The optical system is the larger of the two lenses. The objective lens is found at the back of the riflescope farthest away from the rifle’s stock. Its objective is to return brightness to the ocular lens, the nearest lens to your eye. The objective bell is the scope segment that contains the objective lens, whereas the eyepiece is the segment that includes the ocular lens. A large percentage of rifle scope lenses are both water-resistant and fog-proof.

Why You Must Pay Attention to the Focusing of Scope

Place the Scope and gun in a solid rest. Point the riflescope safely at a light-coloured background entity. The reticle must seem bright and crisp with the riflescope roughly three inches from your eye, and if it doesn’t, the focus must be adapted using the lens.

Mounting the Scope

Split the rings’ upper and bottom halves. Gather the bottom halves. Place the Scope in the folds formed by the underside ring halves point it toward the objective lens. While keeping the firearm steady at rest, gradually move the Scope closer to the eye until the entire field of view is visible.


In brief, a rifle scope is a combination of various components, such as the ones explained in the first half of this article. But, to remind you of the most critical features that you have to check rigorously: (The Lens, Focus Optic and Metal Quality, Magnification Diameters, Exit Pupil Diameter, Eye Relief, and Red Dot) respectively.

Since these features are decisive and play a pivotal role in making an excellent rifle scope for hunters hence, whatever type of gunman you are, the performance of the rifle scope you have will pretty much entirely guarantee the effectiveness of your shooting endeavour.
