EOTech Sights are some of the most DURABLE holographic sights that are even used by law enforcement and the military.
However, it would help if you knew how to zero EOTech sight to get the most out of their accurate sighting.
By zeroing, you make sure that the bullet HITS where you aim.
When I was a complete newbie, I thought I was just bad at shooting or my sight was just defective.
It turns out I just didn’t know how to zero my EOTech!
In this comprehensive guide, I’ll give you step-by-step instructions to zeroing in and answers to related questions.

Zero-in Your EOTech Holographic Sight
Here’s a quick step-by-step guide to zeroing in on your EOTech Holographic sight like a pro!
Things to Prepare
Here are a few things you need to have and prepare before you have your rifle scope zeroed.
- Your weapon (usually a rifle)
- The EOTech sight
- Three rounds or more of ammunition
- A clear range to shoot in
- A stable shooting platform
1. Gathering Materials and Setting Up
First, you need to set up your rifle, ammunition, EOTech sight, and other equipment in a safe and comfortable environment.
I begin by setting up my weapon on a stably supported shooting platform. Next, I place a paper target at a set distance of 25 yards from my weapon.
Doing so will give your EOTech an accurate aim point of up to 300 yards. Next, make sure your EOTech sight is set up properly.
Rotate both windage and elevation dials using the adjusting screw all the way to one direction.
Rotate them back to the other direction by exactly 80 clicks. Both dials have 160 clicks to them, so setting them up at 80 makes them both neutral/zero.
2. Look for the Average Strike Location
I usually load my weapon with three rounds and shoot at the center of the paper target that I previously set up.
I DON’T recommend adjusting your positioning between each shot, as it will affect the zeroing process.
I made this mistake, which resulted in my shots being all over the place.
For now, it doesn’t matter where the bullet hits; just place your reticle as close to the center as possible.
When you’re done, render the weapon safe and go to the target to check the AVERAGE strike location.
The average strike location is located in the middle of where the three rounds strike.
For example, if the three rounds form a triangle, then the average strike location would be the middle of the three points.
If the rounds are too far apart, repeat this process. Try to get the groupings within three inches of each other.
3. Measure the Average Strike Location
The next step starts by creating an imaginary center line on the target running both horizontally and vertically. This line will help determine how far off-center the bullets hit.
First, measure the average strike location left or right towards the imaginary line running from top to bottom.
Then, measure the location up or down towards the line running from left to right.
Record both measurements, and you’ll use this for the next step.
4. Convert Measurements to Needed Clicks
At 25 yards, each click on the screw will adjust the point of impact to 1/8 inch. To move the point of impact 1 inch, turn the screw eight clicks.
This objective is to move the point of impact CLOSER to the center, or where your initial point of aim was when shooting earlier.
5. Adjust Both Elevation and Windage
Now that you know the distance and number of clicks, you need to adjust the point of impact to match the point of aim; it’s time to turn the screw on each turret.
First, adjust the elevation by turning the relative screw clockwise to go down and counterclockwise to go up.
Do this to the converted clicks you recorded in the last step.
Next, turn the relative screw for the windage clockwise to go right and counterclockwise to go left.
6. Last Changes
The final step is to check if the adjustments you’ve made are from an accurate reading of the shots you took.
Fire an additional three rounds and recheck the target.
If the bullet’s point of impact is still off from the point of aim by a lot, go back to the measurements and turn each screw accordingly.
The point of impact should be around 1/2 inch below the point of aim at the center of the target.
In my experience, it was definitely a trial-and-error process, but you’ll eventually get the hang of it!
How Do Holographic Sights Work?
Holographic sights like the EOTech work differently than the typical reflex red dot sight.
Instead of a reflected reticle system, they record the reticle in a three-dimensional space.
It’s then projected onto a holographic film in the optical viewing window.
The reticle also uses collimated light to move it along with the eye position of the shooter.
A holographic sight has a few advantages over a reflex sight.
The optic’s semi-squared shape gives it a WIDER field of view and better peripheral vision.
The EOTech, in particular, also has a 68 MOA ring with a 1 MOA dot that is the finest available in any scope.
My speed and accuracy are great on holographic sights because of this!
Another benefit over red dot sights is that the aiming dot doesn’t expand when used with a magnifier, giving a shooter better precision over a long range.
How to Laser Bore Your EOTech
Bore sighting is just as important as keeping your red dot sights zeroed.
Sighting in a scope is important, especially on the EOTech, providing accurate sighting to 300 yards.
If keeping a sight zeroed means aligning the point of aim with the point of impact, then doing bore sighting aligns the firearm barrel and sight.
A laser bore sight helps make this procedure much fast
