How To Sight In A Red Dot? 3 Steps For Beginner

We call sight in a red dot “Zero.”

The first thing a shooter ought to do after purchasing a new optic is correctly zero their red dot. When the trajectory of your round completely aligns with where you are shooting will depend on your zero.  Your POI stands for your Point of Impact. Your Point of AIM, often known as (POA), is your target. Your red dot is projected onto your target at this point. We’ll talk about the AR-15 family of weapons, which fire 55 gr of XM193 ammo at 3100 fps out of a 16-inch barrel.

How to sight in a red dot: 3 step

How to sight in a red dot, Zeroing should never be carried out carelessly. Whether the shots you fire land where you want them to depends on it. Everyone wants to achieve that, right?There are adjustment dials on your optic that are located at the 12 and 3 o’clock positions.Your elevation (up and down) is adjusted using the dial at the 12 o’clock position, and your windage (left and right) is adjusted using the dial at the 3 o’clock position. Normally, the length of your adjustment dial will be expressed in minutes of angle (MOA).At 100 yards, 1 MOA will equate to roughly 1 inch.

Step 1: Verify the adjusted value.

Red dots designed for rifles often have an adjustment value of 12 MOA; however, I advise you to read your owner’s handbook to make sure. This means that at 100 yards, your point of impact will change by 1/2 inch with each turn of the adjustment dial. Therefore, you will need to adjust to adjusting your point of impact to match your point of aim, for instance, if you are zeroing at 100 yards and your rounds are striking 3 inches above and 3 inches to the left of it.

Step 2: Shoot the target with 3-5 rounds.

You can get a matching Point of Aim and Point of Impact at that distance by adjusting your height down 6 clicks and your windage right 6 clicks. To maintain uniformity, I advise firing 3-5 groups while zeroing. Fire three rounds, watch, and make adjustments. Continue doing this until you consistently have 3-5 round groupings where you want them. As a result, we now discuss zeroing distance.

Step 3: Adjust windage and elevation

How to sight in a red dot, The relationship between the trajectory of your round, the deviation of your windage, and the elevation adjustment value at various distances is another crucial part of zeroing.

The 50/200 yard zero is the most typical and suggested zero you will find with red dot sights.You will need access to a 50-yard range in order to reach this zero. Your windage and elevation dial’s adjustment value will be halved because you are shooting at half the distance.

Zero at a 50-yard range

how to sight in a red dot, ow, each click will measure a quarter of an inch. In order to obtain a matched Point of Aim Point of Impact, you must now modify your elevation 12 clicks downward and your windage 12 clicks to the right. The main advantage of choosing this zero is that, out to 200 yards, your Point of Impact will remain within 2 inches of your Point of Aim.You will be able to engage targets farther away than 200 with the least amount of deviation from your point of aim if you have this zero. See the illustration below for a graphic representation of this.

However, this does not exclude the use of different zeroing distances. They undoubtedly can. Just be aware that between 0 and 250 yards, the difference between your Point of Aim and Point of Impact will be more pronounced.Using techniques like the 25 yard zero, up to 9 inches can be achieved. The 36/300-yard zero method might work better for you if you prefer to fire from a distance greater than 200 yards. The 25, 36, 50, and 100-yard zeros are the ones that red dots use the most frequently. A table of comparisons is provided below.

Three types of Boresighter tools:

1. Laser Boresighter

how to sight in a red dot, The first kind of boresight uses a laser diode to project a dot onto the target. This makes it simple for you to line up your target with the dot or crosshairs on your sight. It is the most common sort of boresighting tool and functions similarly to a laser pointer.

Because of their effectiveness and usability, boresighters are recommended by the majority of seasoned shooters.

The tool’s low parallax is crucial since it allows you to change your pistol without changing its alignment.

2. Optical Boresighter

Without the laser diode, the optical boresighter functions similarly to its laser cousin.

At the end of the rifle barrel, this device is fitted. The red dot is visible through the lens grid. Next, alter the crosshairs so that your target is in line with your sight.

The XAegis Boresighter has over 1700 reviews and a 4/5 rating if you’d want to give it a shot.

3. Visual Boresighting

How to sight in a red dot, When using an AR-style rifle, I prefer to remove the BCG, place a spacer between the upper and lower, and then sight the weapon through the barrel while it is resting.”Eyeballing” your sight is another name for visual boresighting. It entails lining up the bore axis of your gun with its sights using only your eyes.

The method for using this strategy depends on the weapon you are employing. For instance, removing the bolt carrier group and lowering the upper receiver on an AR allows for an unobstructed line of sight through the barrel.

With bolt action rifles, the procedure is the same, but the receiver cannot be taken out. However, by taking off the bolt, you can still see your target clearly through the barrel.
