Zooming In: The Truth About Red Dot Sight Magnification

Are you curious about red dot sights and their magnification capabilities? Whether you’re an experienced shooter or a beginner, understanding how magnification works on red dot sights is crucial for improving your accuracy and target acquisition. In this article, we’ll explore the truth about red dot sight magnification.

What is a Red Dot Sight

Before diving into magnification, let’s first discuss what a red dot sight actually is. A red dot sight is a type of optic used on firearms for aiming at targets. It gets its name from the illuminated red dot that appears on the sight, which is used to help align the shooter’s eye with the target.

How does a Magnified Red Dot Sight Work

A magnified red dot sight is essentially a combination of a red dot sight and a magnifying scope. It has a red dot reticle, which is projected onto the target, but also includes a magnifying lens that allows the shooter to zoom in on the target. The level of magnification can vary, but is usually between 1-4x.

Types of Magnification

There are mainly two types of magnification offered by red dot sights: fixed and adjustable.

Fixed Magnification

Fixed magnification refers to when the red dot sight offers only one magnification option. This option can range from 2x to 10x. Fixed magnification is best for shooters who have a specific range of distance for their shooting and do not intend to shoot at multiple distances.

Adjustable Magnification

Adjustable magnification offers different degrees of magnification. Shooters can adjust the magnification according to their desired range of distance—usually by a dial or on/off switch—allowing flexibility in different shooting settings.

Pros and Cons of Red Dot Sight Magnification

Now that you know how magnification works on a red dot sight, let’s dive into the pros and cons of using magnification on a red dot sight.


  • Improved Accuracy at Longer Distances: One of the biggest advantages of using magnification on a red dot sight is that it can improve accuracy at longer distances. By allowing the shooter to zoom in on targets, they can make more precise shots.
  • Versatility: Because most red dot sights are not solely designed for magnification, adding a magnifier can give a shooter greater versatility in their shooting platform.
  • Easier to Use: Because red dot sights provide a parallax-free view, they’re often easier to use than traditional scopes at closer ranges when used with a magnifier.


  • Reduced Field of View: One of the biggest drawbacks of using a magnifier on a red dot sight is that it reduces the shooter’s field of view. This is because the magnifier narrows the shooter’s view to a smaller area, making it more difficult to track moving targets.
  • Additional Cost and Weight: Adding a magnifier to a red dot sight can add additional cost and weight to the shooter’s setup. Depending on the brand and quality of the magnifier, it can add anywhere from a few ounces to a few pounds to the shooter’s firearm.

Choosing the Right Magnification

Choosing the right magnification for your red dot sight can be a bit tricky. It largely comes down to personal preference and the specific shooting situation. If you’re shooting at targets beyond 100 yards, a magnified red dot sight with a magnification level of around 2-4x is recommended. However, if you’re shooting at closer targets, a non-magnified red dot sight may be more appropriate.

How to use a Magnified Red Dot Sight

Using a magnified red dot sight requires a slightly different technique than using a non-magnified one. To get the most benefit from the magnification, it’s important to maintain proper eye relief. This means keeping your eye at a consistent distance from the eyepiece to ensure a clear image. Additionally, it’s important to practice using the magnification in different lighting conditions to get a feel for how it affects your aim.

Best Practices for Using Red Dot Sight Magnification

If you’re considering adding a magnifier to your red dot sight, there are a few best practices to keep in mind.

  • Choose a High-Quality Magnifier: Investing in a high-quality magnifier can make all the difference when using magnification on a red dot sight. Look for magnifiers that use high-quality glass and are designed specifically for use with red dot sights.
  • Practice at Different Ranges: Practice using your red dot sight with a magnifier at different ranges to determine its effectiveness for your particular needs.
  • Be Mindful of Weight: Adding a magnifier to your red dot sight can add extra weight to your firearm, which can affect your shooting. Be mindful of your firearm’s balance and practice with the added weight to ensure you’re comfortable and accurate.


Magnified red dot sights offer a range of benefits for shooters looking to improve their accuracy at longer distances. However, they also come with some drawbacks, including greater weight and diminished situational awareness.

Choosing the right magnification level for your specific shooting situation is key to making the most of a magnified red dot sight. Remember to practice using the sight and maintaining proper eye relief to get the best results.
