The Structure of Rifle Scope

Don’t miss your target—because experts never! To get mastered with your rifle, you need to put a convey on the part that allows to magnify your target with great accuracy but also provides you safety—that is the scope. Studying the structure of rifle scope will help you get straight with your shooting much efficiently. Putting a cause to the study is that it will help you in the field and you don’t have to figure out tiny parts & their working especially when you will be needing it the most.

The different structural parts are discussed as;

Objective Lens

The objective lens is the front side of the rifle used to transmit light back near our eye because it is located at a larger distance from our generally, greater the magnifying power, the larger will be the objective lens and vice versa. A bigger lens provides you clear and bright picture of Target.

Objective Lens diameter

Mostly, the range of diameter of the objective lens for scope is between 32 mm to 44 mm. A larger diameter means a large and clearer picture for larger magnification and vice versa.

Weight of Objective Lens

We must use a standard weight lens not so much bulky and heavy. A larger lens means large weight. So, we must adjust according to the size requirements of the lens.

Glass Quality Used for Objective lens

Quality of glass is very much important, as we have heard about the larger objective lens means larger magnification but it also depends on the quality of the glass to get a clearer and brighter image.


It is very cheaper and efficient than other lenses—gives a clearer picture. Small objective lens cannot be used for larger range and having no recoil tendency. Medium objective lens provides sufficient range and lower weight. Larger objective lens is used for higher magnification and having efficient range and having clearer picture but having bulky size.

Ocular Lens

To magnify the light of the focal point i.e., the picture showing on the lens of objective lens, ocular lens is used. To clearly focus on the Target and to give vivid picture to the hunter ocular lens is used.

Reticle or Cross Hair

Reticles or Crosshair are used for measuring on the objective lens in origin they were made of hair, so they are also called Choice of a reticle is very crucial aiming at different positions.

Windage Turret

It is used for adjusting horizontal alignments of the reticle. Alignment is measured in MOA (minutes of angle) and MRAD (milliradian). We can adjust windage turret by hand or screwdriver.

Elevation Turret

Elevation turret allows the vertical adjustment of the reticle present on the top of the scope. Windage Turret and elevation turret work very much in the same way.

Parallax (term for distance)

The PARALLAX is inversely proportional to the distance of target. The more is the distance, less will be the movement or displacement of observer or hunter from the already position. Parallax is measured by one divided by parallax angle equals to distance of the start.

Power Ring of the Rifle Scope

To change the magnification of the riflescope power ring is used. Shorter and longer magnifications can be adjusted by using power ring of the rifle scope.

Exit Pupil of the Rifle Scope

It is placed on center of the scope. For larger and brighter picture, the objective lens of large diameter should be used. Exit pupil can be measured as: Diameter of the magnification power divided by the magnification power.

Eye-relief Point of Rifle Scope

Eye-relief is used to see clearly without any obstruction. It is measured in inches and millimeter. As the eye relief range of any rifle scope for coyote hunting or other causes would be different. To protect the shooter’s eye, it is made of extension device. Eye relief is adjustable with the movement of the rifle scope according to the position of the shooter.

How to Mount the Rifle Scope

The whole process of mounting the rifle scope can be explained as;

How to Work Best with the Rifle Scope

The choice of scope depends on the shooter’s choice of shooting. Good quality rifle scope should be valued than rifle because we can easily hit the target having low grade rifle. While using rifle scope following things should be taken under consideration

Choosing Comfortable Position

To aim at your target the hunter or shooter should have taken the comfortable position while shooting. The head and neck should be adjusted carefully while firing.

Mounting the Rifle Scope

Make sure that you are with all equipment needed. The important ones are scope screwdriver, wrench, and the unloaded rifle. Apply a thin layer of oil on your rifle scope and screwdriver before putting them on to work so that they become noiseless and smoother.

Types of Rifle Scopes

The different types of rifle scope depend on the type of magnification factor and the structure as well—the most renowned and basic sorts of rifle scope are given below;

Fixed Scope: As the name shows it is having fixed magnification not adjustable like other rifle scopes. They have generally low prices.

Variable Scope: You may have series of choices to adjust your magnification size of your choice depending on the position of the hunter. You can zoom in or zoom out to get clear picture of the target.
Night Version scope: If you are hunting in low or no light Night version scope is used to clearly see and hit the target due to build in illuminator in the scope that allows to see in full or no light.
Tactical Scope: Usually, they are used by military to hit the target at a shorter range having low magnification level.
Long Range Scope: This scope Is used to hit the target at long having higher magnification level and for efficient working.

Hunting Scope: They are made weather-resistant to get a clearer image of the target mostly used by hunters.
Competition Scope: They are made heavy, large, and of low quality used in competition shooting.
Sniper Scope: This can be adjusted easily used by rifle scope experts giving large information to the hunter.
Scout Scope: They have limited adjustability like tactical scopes used by military and hunters.
Red dot scope: A red dot is shown as a target having no magnification level not suitable for long ranges.


The structure of the rifle should be taken into consideration even after or before getting your hands on the relevant rifle scope for your weapon. Acknowledging the structure will help you identify the best of rifle scopes according to your taste as well as according to the point of measuring the quality. This guide holds the information about some of the crucial key factors that needed to be taken into the study. The parts that are keenly discussed are—objective lenses, ocular lenses, windage turret, elevation turret, and the working of the rifle scope. In the least, the discussion is closed on the types of rifle scopes that are many but each one has its own specific features thus clearing their importance. These sorts of riflescopes are used in different fields depending on their working and magnification level. Therefore, the quality and compatibility of the rifle scope should be up to the mark so that will get the shooter a clearer picture of the target.
