Aimpoint red dot sights have a similar zeroing mechanism as conventional rifle scopes. The red dot has an elevation adjustment knob for vertical dot adjustment on the top and one for horizontal dot adjustment on the right side.
Each Aimpoint red dot has a different click value, which is also one of the downsides of Aimpoint sights. However, Aimpoint has solved this issue with individual targets for each model, which display click values in MOA/cm at 100 m, 50 m, and 25 m.
Aimpoint’s zeroing targets have grid lines, where, for example, a 6.5 mm square indicates that there are two clicks needed for adjustment in order to shoot a target at a 25 m distance. One click is needed for shooting a target at a 50 m distance, and two 6.5 mm squares per click when shooting at a 100 m distance.
With information printed on the Aimpoint zeroing target and by counting the number of squares between the actual hit point and the desired hit point on the target, we can quickly and accurately determine how many clicks are needed to move the red dot adjustment screws.
Zeoring the Aimpoint Red Dot:
As with any optics, for a successful zeroing of the Aimpoint red dot, an adequate amount of support is needed. This support is obtained with a shooting rest or a shooting bag. The target is set at a certain distance, for example, 25 m. Once the rifle is placed in the stand, the bullet can be fired at the target.
Check the hit and set the clicks vertically or horizontally according to the grid lines and the size of the square on the Aimpoint red dot, following the recommendations for shooting at a distance of 25 m. In this case, this means for one square of movement – it is necessary to make 2 clicks in the desired direction.
Then, fire 2-3 bullets again and check the target. If all hits are in the center of the target, this means that the Aimpoint red dot is zeroed. If not, keep on adjusting the dot until the hits are close together in the center of the target – that is how you know the Aimpoint red dot is zeroed.
