Zeroing a red dot scope is the process of aligning the aiming point of the scope with the point of impact of the bullet. This is important for ensuring that the scope is accurate and that the shooter can hit their target. While red dot scopes are generally very easy to use, it is important to zero your scope correctly before using it in a live fire situation.
There are a few different ways to zero a red dot scope, but the most common method is to use a boresighter. A boresighter is a laser device that is inserted into the barrel of the gun and projects a laser beam down the bore. The laser beam can then be used to align the red dot on the scope with the point of impact of the bullet.
