If new to shooting or hunting, using a rifle scope may seem daunting at first. However, once you understand the basics, it can significantly improve your accuracy and precision. In this beginner’s guide, we’ll take you through everything you need to know about reading a rifle scope and how to use it effectively.
|Objective Lens||The lens at the front of the scope that gathers light and|

|Eyepiece Lens||The lens at the back of the scope that magnifies the image|

|Magnification||Refers to the number of times the scope magnifies an object|
|compared to the naked eye. For example, a 10x magnification|
|means the object appears 10 times closer than it actually is.|
|Reticle||The crosshairs or aiming point visible through the scope.|

Parts of a Rifle Scope
Before diving into the specifics of using a rifle scope, let’s familiarize ourselves with its essential parts:
The objective lens is the larger lens at the front of the scope. It gathers light and transmits it to the ocular lens, allowing you to see a clear and magnified image of your target.
The ocular lens, also known as the eyepiece, is located at the back of the scope. It helps focus the light and allows you to adjust the reticle for a sharp image.
Turrets are the knobs on the top and sides of the scope. They are used for making adjustments to windage (horizontal) and elevation (vertical) to align your shots accurately.
The reticle, commonly referred to as the crosshairs, is the aiming point you see through the scope. There are various reticle types available, such as duplex, mil-dot, and BDC, each with its unique advantages.
Choosing the Right Rifle Scope
Selecting the appropriate rifle scope is crucial for optimal performance. Consider the following factors when making your decision:
Consider the Purpose
Different shooting activities require different types of scopes. Whether it’s for hunting, target shooting, or tactical use, the purpose will dictate the ideal features.
The magnification power determines how much the scope can zoom in on the target. Higher magnification is useful for long-range shooting, while lower magnification allows for a wider field of view.
Objective Lens Size
A larger objective lens allows more light to enter the scope, improving visibility in low-light conditions. However, it may add weight to your rifle.
Choose a reticle type that suits your shooting needs. A simple duplex reticle is versatile, while a mil-dot reticle enables range estimation and bullet drop compensation.
Mounting the Rifle Scope
Properly mounting the scope on your rifle is essential for accurate shooting. Follow these steps to ensure a secure and aligned mount:
Preparing the Rifle
Before attaching the scope, make sure your rifle is unloaded and on a stable surface. Remove any existing scope or scope covers.
Properly Aligning the Scope
Place the scope on the mounting rails and align it with the rifle’s bore. Look through the bore and adjust the scope until the reticle centers perfectly.
Tightening the Mounting Rings
Once aligned, tighten the mounting rings evenly to prevent any movement during shooting. Use a torque wrench to ensure you don’t over-tighten and damage the scope.
Zeroing the Rifle Scope
Zeroing your rifle scope means aligning it with the point of impact of your shots. Follow these steps to achieve a proper zero:
Setting Up the Target
Set up a target at a known distance. Shoot a group of rounds and determine the center of the group.
Making Windage and Elevation Adjustments
Using the turrets, make adjustments to move the reticle’s point of aim to match the center of the shot group.
Fine-Tuning the Zero
Take additional shots and make slight adjustments until your shots consistently hit the target’s center.
Understanding MOA and MIL
Minute of Angle (MOA) and Milliradian (MIL) are angular measurements used for adjusting a scope’s reticle. Understanding them is essential for precision shooting:
Minute of Angle (MOA)
MOA is approximately 1 inch at 100 yards. Adjusting by 1 MOA will move your shot impact by 1 inch at that distance.
MIL is a metric unit of measurement, with 1 MIL being approximately 3.6 inches at 100 yards. MIL adjustments are common in military and tactical scopes.
Knowing how to convert MOA to MIL and vice versa can be valuable when using different types of scopes and accessories.
Shooting with a Rifle Scope
Now that your scope is mounted and zeroed, it’s time to start shooting with it. Follow these tips for a successful shooting experience:
Proper Eye Relief
Maintain the correct distance between your eye and the ocular lens for a full and clear sight picture. Avoid “scope bite” by maintaining a safe distance from the scope during recoil.
Breath Control and Trigger Squeeze
Practice steady breathing and a smooth trigger pull to avoid unnecessary movement when shooting.
Keep your eye on the target even after taking the shot. Follow-through helps maintain proper form and ensures you maintain sight on the target.
Maintaining Your Rifle Scope
Taking care of your rifle scope will extend its lifespan and keep it functioning optimally. Follow these maintenance tips:
Regular Cleaning and Inspection
Clean the lenses regularly using a lens brush or microfiber cloth. Inspect for any scratches or damage that may affect visibility.
Protecting from Moisture and Dust
Use scope covers or caps when not in use to prevent moisture and dust from entering the scope.
Scope Covers and Care Tips
Consider using flip-up covers for quick access during shooting. Avoid using harsh cleaning solutions that may damage lens coatings.
Common Mistakes to Avoid
As a beginner, it’s easy to make certain mistakes when using a rifle scope. Avoid these common errors:
Over-Adjusting the Scope
Making excessive adjustments can lead to a loss of zero. Make gradual adjustments and track them to maintain accuracy.
Parallax occurs when the reticle appears to move against the target. Adjust the parallax knob to ensure a clear view and accurate shots.
Using Poor-Quality Rings and Bases
Invest in high-quality scope rings and bases to ensure a secure and stable mount.
