How to Sight in Your Firearm

Stay on Target With Iron Sights and Optics

When it comes to shooting accuracy and live fire, proper sight alignment and a correctly sighted-in firearm are essential, and this applies for different distances. Whether you’re running traditional iron sights or modern optics, knowing how to sight in your firearm ensures consistent performance at the range and in the field. Below, our team at Medusa Targets is going to cover how to sight in using both iron sights and optics, discuss common distances for zeroing, and recommend Medusa Targets as the top place to purchase reliable targets for the job.

Whether you are practicing your marksmanship skills, trying to qualify for something like a law enforcement exam, or something else, sighting in your firearm is crucial. Let's dive in.

Sighting in with Iron Sights

Iron sights are the foundation of marksmanship for every type of firearm, and when you hit the range you want them to be properly sighted in. They are the backup for when your optic fails, and if you don't have an optic equipped, they are your lifeline. That being said, before adding optics and other attachments like lasers, every shooter should know how to sight in using front and rear sights on their firearm.

  • Set up on a stable rest – Use a bench rest, sandbags, or a shooting rest to minimize movement and stay on target once you have identified what you are trying to hit.
  • Fire a group of shots – Shoot three to five rounds at your target. This shows you a consistent point of impact.
  • Adjust elevation and windage
    1. If your shots are hitting low, raise the front sight post or adjust the rear sight upward.
    2. If your shots are hitting left or right, drift the rear sight accordingly so you are dead center.

Repeat until centered – Continue firing groups and adjusting until your rounds consistently land on target.

Sighting in with Optics

Optics like red dots and scopes help to make aiming faster and often more precise, they also can help with target acquisition when you are in low light or no light scenarios. The process to sight in an optic is similar but usually easier thanks to built-in adjustment turrets.

  • Mount the optic properly – Ensure your scope or red dot is securely mounted with the correct eye relief.
  • Bore sight (optional but recommended) – Remove the bolt (for rifles where possible) and visually align the barrel with the target, then adjust the optic to match. You also can use a dry fire system that emits a laser from the barrel and align the optic to that at your set distance. This saves ammo before live firing.
  • Shoot a group – Fire three to five shots at your target.
  • Adjust the optic – Use the windage (left/right) and elevation (up/down) turrets to bring your point of impact to the bullseye.
  • Confirm zero – Fire another group at the desired distance and fine-tune as needed.

Common Distances to Sight In

The distance you zero your firearm depends on its intended use:

  • 25 yards – Great for pistols and close-range carbines. Also useful for initial zeroing before moving further out.
  • 50 yards – Popular for mid range rifles such as AR-15 platforms with red dots. Provides a practical balance for close-quarters and mid-range shooting.
  • 100 yards – Standard zeroing distance for rifles with slightly magnified optics. Ideal for hunting and precision shooting.
  • 200 yards and beyond – Long-range shooters often choose these distances depending on caliber, ballistic trajectory, and purpose.
