Who Needs to Sight in a Red Dot?

Red dot sights are commonly used by hunters, competitive shooters, and law enforcement officers.

However, they are also popular among recreational shooters and those who want to improve their shooting accuracy.

If you are someone who enjoys shooting and wants to improve your accuracy, then a red dot sight may be a great investment for you.

What is a Red Dot Sight and How Does it Work?

A red dot sight, also known as a reflex sight, is a type of optical device that allows you to aim accurately at your target. The sight projects a red dot onto a lens, which appears to be sitting on top of your firearm. When you align the red dot with your target, you can shoot with greater accuracy.

The red dot sight works by reflecting an LED light off of a curved or flat lens. This creates a reticle, or dot, that appears to float in midair. When you look through the sight, your eye focuses on the target, and the dot appears to sit on top of it.

Pros and Cons of Using a Red Dot Sight

Like any piece of equipment, red dot sights have their pros and cons. Here are some of the advantages and disadvantages of using a red dot sight:

What I Like
  • Provides quick targetacquisition: Red dot sights are designed to provide quick target acquisition, making them ideal for situations where you need to shoot quickly.
  • Works in low light conditions: Red dot sights work well in low light conditions and can help you shoot accurately even in dimly lit environments.
  • Improved accuracy: Red dot sights can improve your accuracy by providing a clear sight picture and allowing you to aim more precisely.
What Don't I Like
  • Limited range: Red dot sights have limited range compared to other types of sights. They are generally only effective at distances of 100 yards or less.
  • Battery life: Red dot sights require batteries to operate, and the battery life can vary depending on the model. If the battery dies, your sight will be useless until you replace it.
  • Parallax error: Some red dot sights can suffer from parallax error, which occurs when the reticle appears to move in relation to the target as you change your eye position. This can affect your accuracy if you are not aware of it.

When Should You Sight in Your Red Dot?

You should sight in your red dot whenever you purchase a new sight or make significant changes to your firearm. Changes to your firearm can include installing a new barrel, changing the ammunition you use, or even adjusting your grips. Any changes to your firearm can affect your accuracy, so it’s important to sight in your red dot after any modifications.

You should also sight in your red dot regularly to ensure that your accuracy remains consistent. If you haven’t used your firearm in a while, it’s a good idea to spend some time sighting in your red dot before heading out to the range.

Sighting in a red dot sight requires patience and practice. The process can take anywhere from 10 minutes to an hour, depending on your experience and skill level. Here’s a step-by-step guide to help you get started:

Step 1: Set Up Your Target and Firearm

The first step is to set up your target and firearm. Choose a safe and secure location to shoot, such as a shooting range. Place your target at a distance of 25 yards or as recommended by your sight manufacturer. Make sure your firearm is unloaded and securely mounted on a rest or sandbags.

Step 2: Adjust Your Red Dot Sight

Next, adjust your red dot sight until the dot aligns with your firearm’s bore. This is known as co-witnessing. Co-witnessing ensures that your point of aim and point of impact are the same. To co-witness, look through your iron sights and then adjust your red dot sight until the dot appears in the center of your iron sights.

Step 3: Aim and Shoot

Now that you have co-witnessed your red dot sight, it’s time to aim and shoot. Aim at the center of your target and fire a few rounds. It’s okay if you miss the first few shots; this is just to get a feel for your red dot sight.

Step 4: Adjust Your Point of Aim

After firing a few rounds, examine your target. If your shots are hitting above or below the center of the target, adjust your point of aim up or down accordingly. If your shots are hitting to the left or right of the center of the target, adjust your point of aim left or right.

Step 5: Fine-Tune Your Sights

Continue to fire a few more rounds and make small adjustments to your sights until your shots are hitting consistently in the center of the target. Be patient and take your time with this step; it can take some trial and error to get your sights dialed in.

Step 6: Confirm Zero

Once you have sighted in your red dot sight, it’s important to confirm that it is zeroed properly. This means firing a few rounds at a different target or distance to ensure that your point of aim and point of impact remain consistent.

Alternatives to Using a Red Dot Sight

If you’re not sold on using a red dot sight, there are several alternatives you can consider. Here are some of the most popular options:

  • Iron sights: Iron sights are a simple and reliable option for aiming your firearm. They don’t require batteries and can be used in a variety of lighting conditions.
  • Magnified optics: Magnified optics, such as scopes, offer increased range and precision compared to red dot sights. They are ideal for long-range shooting and hunting.
  • Holographic sights: Holographic sights are similar to red dot sights but use a different technology to create the reticle. They are generally more expensive than red dot sights but offer some advantages, such as unlimited eye relief.

Tips for Improving Accuracy with a Red Dot Sight

Sighting in your red dot sight is just the first step towards improving your accuracy. Here are some additional tips to help you get the most out of your red dot sight:

  • Practice regularly: The more you practice, the better you will become at using your red dot sight. Spend time at the range and practice shooting from different positions and distances.
  • Use proper form: Proper form is essential for accurate shooting. Make sure you have a stable shooting position and use the correct grip and stance.
  • Keep both eyes open: When using a red dot sight, it’s important to keep both eyes open. This helps you maintain situational awareness and can improve your accuracy.
  • Choose the right reticle: Red dot sights come with a variety of reticles, including dots, circles, and crosshairs. Experiment with different reticles to find the one that works best for you.
