How to Adjust a Vortex Scope

Vortex scopes are known for their durability, precision, and clarity, unmatched by most other brands. However, even the most high-quality rifle scope needs occasional adjustments to ensure accuracy. This article will provide a comprehensive guide to adjusting your Vortex rifle scope.

Understanding your Vortex Scope

To get started, you need to understand the basic components of your Vortex scope. The scope consists of two main parts: the objective lens and the ocular lens. The objective lens is the larger lens located at the front of the scope, and it gathers light from the environment to create a clear image. The ocular lens is the smaller lens located at the rear of the scope, and it magnifies this image for your eye. Additionally, your Vortex scope should come with other features such as a reticle, turrets, and parallax adjustments.

Why Adjust a Vortex Scope

Even the most accurate rifle scope can lose its calibration over time. Environmental factors like temperature, humidity, and elevation, as well as bumps or drops, can all cause a riflescope to lose its zero. Inconsistencies in accuracy can be frustrating and potentially dangerous. A riflescope that is out of calibration can lead to missed shots, improper rifle modifications, or even injury.

Zeroing your Vortex Scope

The next step is to zero your Vortex scope. Zeroing your scope involves aligning the reticle with your point of impact (POI) at a specific distance. You should do this at the distance you will be shooting most frequently. To zero your scope, follow these steps:

  • Set up a target at the desired distance.
  • Fire a test shot.
  • Adjust the turrets to move the reticle so that it lines up with the bullet hole on the target.
  • Fire another test shot, and repeat this process until the reticle lines up with the bullet hole.
  • Verify that the reticle remains aligned with the bullet hole when making further adjustments.

Preparing to Adjust your Vortex Scope

Before beginning your adjustments, make sure to follow these steps:

Safety first

Always make sure your rifle is unloaded before adjusting your riflescope.

Mount your scope

Mount your Vortex scope onto your rifle using rings that are of the correct size. Make sure the screws are tightened appropriately, but not over-tightened.

Set your eye relief

Adjust your eye relief until you see a full image of your target when you bring the rifle to your shoulder. Adjust the scope position if needed for a comfortable and clear view.

Gather your tools

Use the Vortex-provided torx wrench to adjust your scope. This specialized tool is designed for precision adjustment.

Set up your workspace

Find a stable surface to place your rifle while making adjustments. It is best to adjust your riflescope at a shooting range or outdoors—any location with plenty of space and safety features.

Step-by-Step Guide to Adjusting a Vortex Scope

Adjust the Windage

The windage is the horizontal adjustment on your riflescope. Use the torx wrench to loosen the windage screw. Then, adjust the scope right or left until it is hitting the target where it should.

Adjust the Elevation

The elevation is the vertical adjustment on your riflescope. Use the torx wrench to loosen the elevation screw. Then, adjust the scope up or down until it is hitting the target where it should.

Adjust for Parallax

Parallax occurs when the scope’s reticle and target are not aligned properly, causing the shooter to perceive their aim to be slightly off. Dial in the parallax by adjusting the parallax knob until the reticle, and the target appears as though it is on the same focal plane.

Lock it Down

After making all these adjustments, lock down the adjustment screws using the torx wrench to ensure that the adjustments are safe and secure.

Common Mistakes to Avoid

As you adjust your Vortex scope, there are several common mistakes you should avoid. One of the most common mistakes is overcompensating for elevation or windage. Remember to make small adjustments and to test your scope frequently as you make changes. Additionally, make sure to check that your scope is level and that your mounting rings are secure.

Tips and tricks for adjusting a Vortex scope

Use a properly sized wrench

Using the correct sized torx wrench can make adjusting your riflescope easier and less likely to cause damage to your riflescope.

Adjust in small increments

Make small adjustments at a time while testing your aim in between. This will prevent over-adjustment and help you achieve more accurate results.

Take your time

It can be tempting to rush the adjustment process. However, taking the time to properly adjust your riflescope, step-by-step, will ensure the most accurate results possible.


Maintaining your Vortex scope is essential to ensure optimum performance and longevity. Here are a few maintenance tips:

  • Keep your scope clean by wiping it with a microfiber cloth.
  • Store your scope in a dry, cool place, preferably in a case.
  • Avoid dropping your scope or exposing it to extreme temperatures.
  • After every use, check for any loose screws or damaged components.


In conclusion, adjusting your Vortex scope can seem daunting at first, but it is a simple process when broken down into simple steps. Always remember to follow safety precautions, choose the right tools for the job, and go slowly to achieve the most accurate results.
