How to Zero a Red Dot (Easy Beginners Guide)


Red dots are becoming increasingly popular among gun enthusiasts due to their unparalleled ease of use and pinpoint accuracy. They provide an excellent short to medium-range shooting experience, particularly for those just starting with shooting guns. However, even the best red dot can be inadequate if not zeroed correctly. In this article, we’ll guide you on how to zero a red dot and ensure you hit your targets.

Understanding MOA (minute of angle)

Minute of angle (MOA) refers to the measurement of shooting accuracy, particularly when using a red dot on a rifle. One MOA equals 1 inch at 100 yards. Knowing how to use MOA to adjust the red dot is critical when zeroing in.

Making Red Dot Adjustments

Red dot adjustment knobs for windage and elevation settings on most red dot sights. Adjustments typically 1 MOA per click. So, six clicks equal one inch adjustment at 100 yards.

To adjust the red dot upwards, rotate the up arrow on the red dot. Every six clicks will make the red dot move up by one inch at 100 yards. Use a pen or screwdriver to make your adjustments.

Rear of Cartridge Used for Adjustment in the Field

Sometimes in the field, you may not have the necessary tools to adjust your red dot. Don’t worry; the rear of a cartridge can be used for making adjustments when in the field. You can use the rim of the cartridge, slide it under the knob to raise it and press on the knob to lower it.

Consistency with MOA

MOA stays consistent across different distances, which makes it easy to adjust your red dot sight accurately, regardless of where you are shooting. For example, if you’re point of aim is off by one MOA, then adjust the red dot appropriately.

1 MOA at 50 yards equals 1/2 inch adjustment, while 1 MOA at 25 yards equals 1/4 inch adjustment. It’s essential to understand how to adjust your scope and optic, ensuring you hit your target.
