Whether you’re new to the world of Red Dots or looking to refine your skills, we’ve got you covered.

What is a Red Dot Sight?

Red Dot sights have earned their place as a game-changer in the world of firearms optics and pistol sights. These innovative devices are designed to simplify target acquisition and improve accuracy, making them a favorite among shooters and hunters. But what exactly is a Red Dot?

Definition of Red Dot Sight:

A Red Dot is a non-magnifying reflector sight that provides an illuminated aiming point in the form of a red dot or reticle. This dot is superimposed on the target and allows for quick and precise aiming. Unlike traditional pistol sights or magnified scopes, Red Dot sights offer several advantages that make them highly desirable for various shooting applications.

Advantages of Red Dot Sights:

Rapid Target Acquisition: Red Dot sights allow shooters to quickly acquire their targets, as there’s no need to align multiple sights or focus on a crosshair.

Both-Eyes-Open Shooting: With both eyes open, shooters maintain situational awareness, crucial for tactical and hunting scenarios.

Parallax-Free Aiming: Red Dot sights are designed to be parallax-free, meaning the point of impact remains consistent, even if your eye’s position shifts.

Versatility: Red Dot sights are versatile and can be used on a wide range of firearms, from handguns to rifles and shotguns.

Low-Light Performance: Many Red Dot sights offer adjustable brightness settings, making them effective in low-light conditions.

In a market flooded with options, Accufire stands out as a brand committed to delivering high-quality Red Dot sights. Our products are engineered for superior performance.

The Basics of Red Dot Sights

To effectively sight in a Red Dot, it’s essential to understand the basic components that make up these sights. Red Dot sights come in various designs, including tube-style and open-style models. Let’s take a closer look at these components and what sets them apart.

Components of a Red Dot Sight:

A typical Red Dot comprises several key components:

Objective Lens: This is the front lens of the sight that collects light and projects the reticle onto the lens.

Emission Source: Red Dot sights utilize either LED or holographic technology to generate the reticle. The emission source emits the red dot or reticle pattern.

Parallax-Free Lens: The lens housing the reticle is designed to be parallax-free, meaning the reticle remains on target, regardless of the shooter’s eye position.

Adjustment Turrets: These are used to fine-tune windage (horizontal) and elevation (vertical) settings, allowing precise alignment of the reticle with the point of impact.

Mounting System: Red Dot sights can be mounted on various firearms, and the mounting system secures the sight in place. The type of mount depends on your firearm and personal preference.

Why Zeroing (Sighting In) is Crucial

Before we dive into the process of zeroing in your Red Dot, it’s essential to understand why this step is so crucial. Zeroing, also known as “sighting in,” ensures that your point of aim matches the point of impact. Here’s why it matters:

Precision and Accuracy: When your Red Dot is properly zeroed, your shots will consistently hit where you aim. This is essential for target shooting, hunting, and self-defense situations where accuracy is paramount.

Consistency: Without proper zeroing, every shot you take could land in a slightly different place, making it challenging to predict where your bullets will go.

Optimal Performance: To make the most of your Red Dot sight’s capabilities, it’s essential to align it correctly with your firearm. Zeroing allows you to maximize your sight’s performance.

Accufire understands the significance of precise zeroing, and we’re here to guide you through the process to ensure that your Red Dot sight lives up to its potential.

How to Zero in a Red Dot Sight

Zeroing in your Red Dot sight is a step-by-step process that requires attention to detail. Accufire Red Dot sights are designed for ease of use and precision.

Mount the Red Dot Sight

Ensure your Red Dot is securely and correctly mounted on your firearm. Accufire provides various mounting options, so choose the one that suits your specific needs.


Boresighting is an initial alignment step to get you on target more quickly. You can use a boresighting tool or, in some cases, visually align your sight with the bore of your firearm.

Choose Your Distance

Decide on the distance at which you want to zero your Red Dot. This could be 25 yards to 50 yards for pistol sights, or another distance, depending on your shooting requirements.

Adjust Windage and Elevation

Utilize the adjustment turrets on your Red Dot to fine-tune windage (left-right adjustments) and elevation (up-down adjustments). Make small, deliberate adjustments and fire a series of shots to check your progress.

Continue this process until your shots consistently hit the bullseye at your chosen distance.

Confirm Your Zero

After making adjustments, take additional shots to confirm that your Red Dot is correctly zeroed. Consistency is the key to a successful zero.

By following these steps and taking your time with adjustments, you’ll achieve an accurate zero for your Red Dot sight. Accufire’s best pistol Red Dot sights are engineered to make this process straightforward and reliable.

Common Mistakes to Avoid

Zeroing a Red Dot sight can be straightforward when done correctly, but there are common mistakes to watch out for:

Rushing the Process: Take your time when making adjustments. Hasty corrections can lead to inaccurate zeroing.

Neglecting Your Mount: Ensure your Red Dot is securely mounted. Loose or improperly mounted sights can result in inconsistent shots.

Ignoring Environmental Factors: Wind, lighting conditions, and other environmental factors can affect your shot placement. Account for these variables when zeroing.

Neglecting Maintenance: Regularly check and maintain your Red Dot to keep it in optimal condition.

Accufire recommends paying close attention to these potential pitfalls to achieve the best results with your Red Dot.

Tips and Best Practices

Practice Makes Perfect: Regularly practice with your Red Dot sight to build muscle memory and improve your shooting skills.

Use the Right Ammunition: Different types of ammunition can affect your point of impact, so choose the one that works best for your needs.

Keep Your Lens Clean: Ensure your sight’s lens is free from debris and smudges for a clear view.

Adjust Brightness: Modify the sight’s brightness settings to match your environment for optimal visibility.

Keep Records: Maintain a log of your zeroing adjustments and shooting conditions for reference.
