How to Zero a Scope with a Mirror?

Items Needed To Reset Your Scope:

  1. Your scope
  2. Screwdriver or Allen wrench depends on your scope

There are two methods to reset your scope to factory zero:

  1. The mirror method
  2. The counting method

Here’s How You Can Reset Your Scope?

Mirror Method

1. Put your scope flush with the mirror

A crosshair is an optical device used by marksmen to aim firearms. A crosshair is usually located near the center of the target. When the shooter aims at something, he or she looks into the eyepiece of the scope and sees the reticle. If the reticle is centered, the shooter knows that he or she is aiming directly at the target. If the reticle isn’t centered, the shooter must adjust the scope until the reticle is centered.

2. Line up the shadow of the reticle with the reticle itself

Resetting to factory zero means lining up the shadow of the crosshairs with the reticle itself, which is done by adjusting the elevation and windage turrets. There is no specific way to complete this step, but it is more trial-by-fire. Keep adjusting the turrets to get the shadow and reticle aligned.

Counting Method

Here’s a step-by-step guide on you you can zero your scope:

  1. You need to turn the top turret as far as it goes in one direction before you can adjust the elevation.
  2. On your elevation turret, rotate it up in a clockwise direction. After reaching its maximum rotation, stop when you feel resistance. Turret may also rotate counterclockwise. Follow the direction of the arrow above the turret.
  3. The number of clicks should be equal to the number of times the turret rotates in the opposite direction.
  4. Divide the number you counted in half and count the clicks again. Turn the turret to the divided amount. Divide your number by 2 and for example you get 12. Then turn the elevation knob up in a clockwise direction and count the clicks again until you get 12.
  5. Windage turrets should be turned clockwise or counter-clockwise until you feel resistance. Then count how many times you turn the turret before you stop. Divide that number by 2. That’s your new setting.

Things to Consider…

Resetting your scope to factory 0 is an important first step when using a new gun or a gun that you haven’t used for a while. You should always do this before shooting.

A scope has two main parts. First, there is the objective lens. This is what actually focuses light onto the reticle. Second, there is the eyepiece. This is what you look into to view the target. There are different types of scopes, such as reflex, tube, and riflescope.

Optic alignment takes about 5 seconds. Counting methods take longer, but less than 10 minutes.
