Quick Answer
For AR-15 rifles, the best zeroing techniques involve shooting at varying ranges, using a mil-dot reticle for precise adjustments, and employing the "Walk-Back" method for accurate zeroing in on a target.
Precision Shooting at Varying Ranges
To zero your AR-15, it’s essential to shoot at various ranges, ideally between 100 to 500 yards. This allows you to account for the rifle’s trajectory and make accurate adjustments. At each range, fire three shots and use the average point of impact to make adjustments.
Using a Mil-Dot Reticle
A mil-dot reticle is an excellent choice for zeroing an AR-15, as it allows for precise adjustments. To use a mil-dot reticle, identify the target’s size in mils and calculate the necessary adjustment. For example, if the target is 1 mil in size, adjust your scope by 1 MOA (minute of angle) at the desired range.
Walk-Back Method for Accurate Zeroing
The Walk-Back method involves shooting at a target, then walking back 10-20 yards while keeping the rifle on target. This allows you to make precise adjustments based on the point of impact. For example, if the point of impact is 1 inch high at 100 yards, walk back 10 yards and adjust your scope accordingly.
