How to zero iron sights?

The first way is to use a tool such as a sight pusher, which will help you adjust the sights without damaging them. You can also use something like a pin or even the eraser end of a pencil to make the adjustments. Once you have determined which direction your sights need to be moved in to properly aligned, use your chosen tool to move them that way very slowly and carefully. Take care not to damage the sights by applying too much pressure. If everything is lined up correctly, you will see both the front and rear sights sitting parallel on top of each other when looking down the barrel of the gun.

To zero iron sights, line up the crosshairs on the target and adjust the elevation and windage screws until the bullet hits the desired point of impact.
Many guns have a “battle sight zero” that will hit a target at a certain distance (usually 50-100 yards), so it’s best to start there and then make finer adjustments as needed. Remember to always test your zeroed sights in different conditions, as your surroundings can affect how well your bullets hit their target.

The most common way is to use a target at a known distance and adjust the sights until the bullet hits the center of the target. You can then use this adjusted position to aim at targets at other distances.
Another way to zero your sights is by using a laser or boresight device. This involves sighting your weapon on a laser or boresight target and adjusting the sights until the beam hits the center of the target. Once you have done this, you can use this adjusted position to aim at targets at other distances.

One way is to use a weapon’s sighting mechanism, such as a scope or laser sight. Another way is to use what is called the “box method.” The box method entails drawing an imaginary square or rectangle in front of the target and adjusting the sights until the bullets land in the center of the square or rectangle. A third way, which is less accurate but simpler, is to adjust the sights so that they are level with the ground. Once they are adjusted, aim at a target and shoot. If the bullets hit high or low, they then adjusted sights accordingly.

One of the way is to use a target and adjust the sight until the bullet hits the bulls-eye.
Another way to zero iron sights is by using a laser pointer. First, align the laser pointer on the target and then adjust the sights so that the beam of light intersects with the laser pointer.
A third method is to use a measuring device such as a cartridge or ruler. Place the object at varying distances from the gun and measure how high or low the object the bullet impacts. Once you have determined this, adjust your sights accordingly.

You can to the elevation and windage knobs on the scope to center the crosshairs. First, adjust the elevation knob until the crosshairs are aligned with the target. Next, adjust the windage knob until the crosshairs are also aligned with the target. Finally, pull down on both knobs at once to lock them in place. Your iron sights should now be zeroed in and ready to use!
