Selecting the Right Scope
Choosing the appropriate scope for your firearm is essential for ensuring accurate and successful shooting. Here’s a comprehensive guide to selecting the right scope:
Magnification: The magnification power of a scope refers to its ability to enlarge the target, making it easier to see and aim at. For general-purpose use, a magnification range of 3-9x or 3-12x is suitable. For long-range shooting, higher magnification options such as 12-42x or 18-56x may be preferred.
Objective Lens Size: The objective lens, located at the front of the scope, determines the amount of light entering the system. Larger objective lenses (e.g., 40mm or 50mm) gather more light, resulting in brighter images and improved low-light performance. However, larger lenses also increase the overall size and weight of the scope.
Reticle: The reticle is the crosshair pattern displayed within the scope. There are various reticle designs available, each with its own advantages. Common types include the duplex reticle, BDC reticle, and Mil-Dot reticle. Consider the shooting discipline and personal preferences when selecting a reticle.
Other Considerations:
Adjustable Objective: Some scopes feature an adjustable objective (AO) lens that allows you to fine-tune the focus for parallax correction at different distances.
Turrets: The turrets on a scope allow you to adjust windage and elevation. Look for turrets with precise clicks and clear markings.
Durability: Ensure the scope is constructed with durable materials that can withstand recoil and harsh weather conditions.
Warranty: A reputable manufacturer will offer a warranty on their scopes, providing peace of mind in case of any issues.
Proper Eye Relief
Eye relief refers to the distance between the last lens of the scope and your eye when you have the rifle properly shouldered and your eye aligned with the reticle. Proper eye relief is critical for several reasons:
1. Safety
If your eye is too close to the scope when the rifle fires, the recoil can cause the scope to hit you in the eye, potentially causing serious injury.
2. Accuracy
Proper eye relief is essential for accurate shooting. If your eye is not positioned correctly behind the scope, you will not be able to see the reticle clearly, which will make it difficult to aim accurately. In addition, if your eye is too close to the scope, the recoil of the rifle can cause your head to move back, which can also throw off your aim.
3. Comfort
Proper eye relief is also important for comfort. If your eye is too close to the scope, you may experience eye strain or fatigue. In addition, if your eye is too far from the scope, you may have to crane your neck to see the reticle, which can also be uncomfortable.
The correct eye relief for a scope is typically measured in millimeters and is usually specified in the scope’s manual. To find the correct eye relief for your scope, follow these steps:
| Step | Description |
|---|---|
| 1 | Mount the scope on your rifle and shoulder the rifle as if you were preparing to shoot. |
| 2 | Close your non-shooting eye and look through the scope with your shooting eye. |
| 3 | Move your head back and forth until you find the position where the reticle is sharp and clear and there is no black ring around the edge of the scope’s field of view. |
| 4 | Once you have found the correct eye relief, tighten the scope’s mounting screws. |
It is important to note that the correct eye relief for a scope can vary depending on the individual shooter. Some shooters may prefer a slightly longer or shorter eye relief than the manufacturer’s recommended setting. It is important to experiment with different eye relief settings to find the one that is most comfortable and accurate for you.
Focusing the Reticle
Adjusting the focus of the reticle is crucial to ensure a clear and precise aiming experience. Here’s a step-by-step guide to help you achieve optimal reticle focus:
1. Determine the Direction of Blur
Look through the scope and identify whether the reticle is blurry in front of or behind the target. This will help you determine the direction of adjustment.
2. Locate the Focus Adjustment Ring
Find the focus adjustment ring located on the eyepiece of the scope. It typically has a ribbed surface or a knurled knob for easy manipulation.
3. Adjust the Focus
Turn the focus adjustment ring slowly while keeping your eye on the reticle. Rotate it in the direction opposite to the perceived blur. For example, if the reticle is blurry in front of the target, turn the ring clockwise to bring it closer.
4. Use a Fine-Focus Adjustment
Once you have achieved a general level of focus, some scopes offer a fine-focus adjustment ring. Use it to make precise adjustments and obtain the sharpest possible reticle.
5. Optimize Focus for Different Distances
The focus of the reticle may need to be adjusted for different target distances. Here’s how to achieve optimal focus for specific ranges:
| Target Distance | Focus Adjustment |
|---|---|
| Close Range (up to 50 yards) | Focus on the target itself |
| Mid-Range (50-200 yards) | Focus on a point halfway between the target and the scope |
| Long Range (over 200 yards) | Focus on infinity by turning the focus adjustment ring counterclockwise until the reticle appears sharp against a distant object |
Adjusting Parallax
Parallax is the apparent movement of an object when viewed from different angles. In optics, it refers to the slight shift in the apparent position of the reticle or target image when the observer’s eye moves behind the scope. Parallax can cause errors in aiming, especially at long distances.
To eliminate parallax, it’s crucial to ensure that the observer’s eye is centered behind the scope and that the reticle is adjusted so that it appears coincident with the target. Here’s a detailed guide on how to adjust parallax in a scope:
- Set the target: Place a target at a known distance, typically 100 yards.
- Center the reticle on the target: Use the windage and elevation knobs to align the reticle with the center of the target.
- Close one eye: Close one eye and focus on the reticle.
- Move your head slightly: Move your head slightly up and down and from side to side.
- Observe the reticle’s movement: Notice whether the reticle moves relative to the target. If it does, you need to adjust the parallax.
- Focus the objective lens: Adjust the objective lens by rotating the focusing ring until the reticle appears sharp and clearly defined. This will usually eliminate parallax.
Troubleshooting Parallax Errors:
If you encounter parallax errors, it could be due to one of the following factors:
| Factor | Cause | Remedy |
|---|---|---|
| Incorrect eye position | Not centered behind the scope | Reposition your eye in the center of the scope |
| Objective lens not focused | Reticle not sharp | Adjust the objective lens until the reticle is clear |
| Damaged scope | Internal optics misaligned | Contact the manufacturer for repair |
Maintaining a Stable Position
Achieving a stable position is crucial for effective scope sighting. Follow these tips:
1. Proper Stance
Stand with your feet shoulder-width apart and your weight evenly distributed. Avoid slouching or leaning forward.
2. Grip the Stock
Hold the stock firmly with your dominant hand, with your index finger resting comfortably on the trigger. Ensure the grip is not too tight or loose.
3. Support the Rifle
Rest the rifle on a solid surface like a bench or a stable shooting stick. This will provide support and reduce recoil.
4. Position the Elbow
Place the elbow of your dominant arm directly under the rifle to create a stable base. Keep your elbow slightly bent.
5. Rest Your Non-Dominant Hand
Support your non-dominant hand on your body or a shooting bag. This will provide additional stability.
6. Breathing Techniques
Control your breathing to minimize wobble. Inhale slowly and exhale just before taking the shot.
7. Relaxation and Focus
Relax your body and mind, focusing on the target. Avoid unnecessary movement or muscle tension. Remember, stability is key to accurate shooting.
| Tip | Description |
|---|---|
| Use a shooting bag | Provides a stable rest for your non-dominant hand. |
| Wear a shooting jacket | Provides support and reduces recoil. |
| Practice regularly | Improves stability and muscle memory. |
Troubleshooting Issues
Incorrect Eye Relief
Ensure the scope is positioned at the correct distance from your eye. The ideal eye relief varies with different scopes. Refer to the manufacturer’s instructions for specific recommendations.
Blurry Reticle
Adjust the focus knob on the scope’s eyepiece until the reticle becomes sharp and clear. Some scopes also have a diopter adjustment to fine-tune the focus for your specific eyesight.
Scope Drooping or Canting
Tighten the scope mounts or rings firmly to secure the scope in place. Verify that the mounts and rings are compatible with your rifle and scope. Consider using a level to ensure the scope is mounted straight.
Parallax Issues
Adjust the parallax setting on your scope to match the distance to your target. Parallax occurs when the target appears to shift relative to the reticle as you move your head. Correcting parallax ensures accurate aiming.
Double Images
If you see double images when looking through the scope, it could indicate a misalignment of the scope’s internal components. Contact the manufacturer or a qualified gunsmith for professional repair.
Scope Not Holding Zero

Fogging or Condensation
Purge the scope with nitrogen to prevent fogging or condensation in humid environments. Alternatively, wrap silica gel packets around the scope for moisture absorption.
Illuminated Reticle Malfunction
Replace the battery in the scope or check the electrical connections for loose wires or contacts. Ensure the illuminated reticle is enabled in the scope’s settings.
Damaged Reticle
If the reticle has been physically damaged, it may need to be replaced. Contact the manufacturer for repair or replacement options.
Scope Not Tracking Target
Verify that the scope’s internal mechanism is functioning correctly. Ensure the scope’s turrets are not loose or damaged. If tracking issues persist, consider having the scope professionally checked or repaired.
How to Sight in a Scope
Sighting in a scope is the process of aligning the reticle (the crosshairs or other aiming point) of the scope with the point of impact of the bullet fired from your rifle. This is a crucial step for ensuring accuracy when shooting, as even a slight misalignment can result in shots being off target.
There are a few different ways to sight in a scope, but the most common and effective method is known as the “boresighting and fine-tuning” method. This method involves using a boresighter to initially align the scope with the bore of the rifle, and then fine-tuning the alignment by shooting at a target.
To sight in a scope using the boresighting and fine-tuning method, you will need the following equipment:
- A boresighter
- A rifle and ammunition
- A target
- A wrench or other tool for tightening the scope’s mounting screws
Once you have gathered your equipment, you can begin the sighting-in process.
